Highway/City Mode

Setting your detector to City mode delays all X band audio alerts until the signal strength reaches Level 3. (A single beep will sound when the signal is first detected.) This will reduce false alerts while you are driving in, or near, urban areas where there are many sources for conflicting X band signals such as microwave towers and automatic door openers. To change settings, follow the procedure listed below, which indicates what you will see and hear (either in Voice Alert or Tone Alert mode) as you complete each step. The factory setting is Highway mode.
UltraBright Data Display Brightness
You can choose from three (3) settings for Brightness of the display. You can cycle through the settings by repeatedly pushing the Dim button. The factory setting is Bright.

The tables on the following pages show you the types of Signals your detector will detect, as well as the voice and visual alerts it provides for each of them.

Audio Alerts

In Voice Alert mode you will first hear several tones, then a voice message announcing the type of signal detected, followed by more tones. In Tone Alert mode, you will hear the tones only. In both Voice Alert and Tone Alert modes, a distinctly different alert tone is used for each type of signal detected (including separate tones for each laser signal). For X, K and Ka band radar signals, the tones will repeat faster as you approach the signal source. The repeat rate of the tones gives you useful information about the signal detected.

Strobe Alert

Special strobes mounted on the light bars of authorized emergency vehicles (fire trucks, police cars, ambulances) automatically change traffic signals as the vehicle approaches an intersection. These strobes and the special strobe detectors located on the traffic signals, introduced fairly recently by 3M and Tomar, are already in use in more than 1000 cities nationwide. Cobras exclusive Strobe Alert detector will detect these special strobes and give an emergency vehicle alert. When you receive such an alert, please watch for an approaching emergency vehicle and pull over to allow it to pass. To inquire about coverage in your area, contact your local fire and police departments.
Three (3) band frequencies have been approved by the Federal Communications Commission (FCC) for use by speed monitoring radar equipment: X band K band Ka band 10.525 GHz 24.150 GHz 33.400 36.00 GHz
Your detector detects signals in all three (3) radar bands.

VG-2 And Spectre 1

VG-2 and Spectre 1 are detector detectors that work by detecting low-level signals emitted by most radar detectors. Your detector does not emit signals that can be detected by VG-2 or Spectre 1, but does detect VG-2 and Spectre 1 signals and will alert you when a device is in use near your vehicle, if you so choose.

LIDAR (Laser)

The correct name for the technology that most people refer to as laser is actually LIDAR, which stands for Light Detection and Ranging. LIDAR operates much like radar. Its signal spreads out like a radar signal, though not as widely. Unlike radar, LIDAR must have a clear line of sight to its target vehicle throughout the entire measurement interval. Obstructions such as sign posts, utility poles, tree branches, etc., will prevent valid speed measurement. Some common questions about LIDAR include: s Does weather have any affect on LIDAR? Yes. Rain, snow, smoke, fog, or airborne dust particles will reduce the effective range of LIDAR and can, if dense enough, prevent its operation.
Safety Alert Traffic Warning System
FCC-approved Safety Alert transmitters emit microwave radar signals that indicate the presence of a safety-related concern. Depending on the frequency of the signal emitted, it can indicate a speeding emergency vehicle or train, or a stationary road hazard. Because these microwave signals are within the K band frequency, most conventional radar detectors will detect Safety Alert signals as standard K band radar. Your detector, however, is designed to differentiate between standard K band and Safety Alert signals, and give separate alerts for each. Safety Alert technology is relatively new. Safety Alert transmitters can be found in limited numbers in all 50 states, but the number is growing. Depending on your location, you may not receive these alerts regularly and may often encounter emergency vehicles, trains and road hazards without being alerted. As the number of transmitters increases, these alerts will become more common. When you receive such an alert, please watch for emergency vehicles ahead of you, on cross streets and behind you. If you see an emergency vehicle approaching, please pull over to the right side of the road and allow it to pass.

18 English

Can LIDAR operate through glass? Yes. Newer LIDAR guns can obtain readings through most types of glass. However, the laser pulse also can be received through glass to trigger an alarm by your detector. Can LIDAR operate while in motion? No. Because LIDAR operates by line of sight, the person using it cannot drive the vehicle, aim and operate the gun all at the same time. Is LIDAR legal to use? Yes. It is legal in all 50 states.

BELTRONICS Express 925 Subjective Evaluation
I. Physical and Operational Characteristics The BEL Express 925 has an all-black case and its operations are controlled by a row of four top-mounted buttons. (The 935 model shares its case and is identical save for a text display and additional features.) The display has red alpha-numeric characters for operating mode and signal strength as well as laser identification. Secondary icons depict radar band
identification. Display brightness can be adjusted in three steps. In full-dark mode a dim, horizontal red segment stays lit to verify power-on. Alerts are audible-only in this mode. Four user-selectable options are available: SWS on/off, VG-2 Guard on/off, SWS voice alerts on/off and radar/laser voice alerts on/off. Finding programming mode isnt an intuitive process and new owners will need to keep the owner manual handy. However, three of the four options are little-used while the fourth, voice alerts, will generally remain unaltered once the owner makes a choice. There are three operating modes: City, City All and Highway. An audio confirmation accompanies each change: one beep for City and City All, two beeps for Highway. City mode raises the threshold at which audible X-band alerts are issued while City All extends that strategy to all three radar bands. The two BEL models were the only units to offer this feature and we found it contributed to a significant reduction in urban false alarms. Highway mode acts in the conventional manner, delivering maximum sensitivity for open-road conditions. II. Alert Systems Radar band identification icons are yellow (X band) and red for K and Ka band. Their generous size, intensity and color greatly assist in visual identification, easing the operator's task. The yellow X-band icon is generally unreadable in direct sunlight. Fortunately, since police worldwide almost universally stopped using Xband radar over a decade ago (only three U.S. state highway patrols continue to use it in any number), this icons color is of commensurately little consequence. Detection of VG-2 radar detector detectors is accompanied by a special audible alert and a flashing H or A in the display. The BEL isnt immune to the early model VG-2, which detected it at 2,396 feet, well beyond the range at which the 925 was able to detect the RDD. It proved much more difficult to detect by our late model VG-2, by far the more commonly used of the two. But since some of the old VG2s are still around, driving with the BEL 925 could be risky for truckers and for those who

officer is responding to something like a Code 78 callofficer needs assistancehell be running every bit this fast.) Assuming that the civilian is driving at 70 mph, a 4556 mph speed differential would translate to advance warning for the BELequipped driver of 47 to 58 seconds. To a Cobraequipped driver: 1.0 to 1.25 seconds. VII. Laser Sensitivity The BEL 925 ranked equal with all but the Whistlers, which led the group. VIII. Overall Evaluation The BEL Express 925 and 935 are well constructed, sophisticated detectors with outstanding performance. Based on past tests we find that they can compete with units priced up to $399, including many in the BEL model lineup. Each has a comprehensive feature set, excellent audio and visual alert systems, effective, high quality mounting hardware and comes with a complete set of accessories. The operator manual is well written and informative. These units stand out for their superior detection range and a price/performance ratio that is best-in-class by a significant margin.
high speed. The average driver doesnt check his mirrors from one month to the next and sirens at that speed are so useless that no state patrol trooper that weve met in the past 25 years even bothers to switch it on. At 115 mph, a speed routinely attained by a trooper trying to catch up to a speeder, the patrol car is moving along at 169 feet per second. (The last Ford Crown Victoria police car we tested, even burdened with a drag-inducing light bar, hit a radar-verified 126 mph, a velocity equal to 182 feet per second. If the

Highway. Switching between the two requires 1.15 seconds. II. Alert Systems Radar band identification icons are yellow (X), pale green (K and Ka) and red (laser). A yellow V indicates VG-2 and Spectre Mk I detection and a red S denotes Strobe Alert. This function is intended to alert the driver to a nearby emergency vehicle equipped with an Opticom or Tomar traffic-signal-changing strobe light transmitter. And there are four different visual alerts for various brands of lasers. Radar signal strength is shown via red digits, 1 through 5, and by beep frequency. There are 9 audible alerts: one each for the three radar bands plus laser, Strobe Alert and VG-2/Spectre alert. There are also three audio tones for Safety Alert signals (the competitor to the Safety Warning System or SWS), one each for Emergency Vehicle, Road Hazards and Trains. Maximum audio volume was 96 dB, best of the group. III. Features Cobra offers a fairly competitive array of options in the XRS 9300 including auto mute, manual mute and preferred settings memory. The radar detector detector-detection feature proved useless. The XRS 9300 detected a late model VG-2 at only 79 feet and failed entirely to detect an earlier VG-2. And while it can detect the Spectre Mk I, none of these is being used in U.S., all having been replaced by Mk II versions that are both undetectable by the Cobra and which can spot this detector from 1,359 feet away. The Cobra is, however, undetectable by the VG-2. The IntelliMute feature is intended to automatically mute all radar alerts when the cars engine speed is running at low RPM. The theory is that if the driver is slogging through rush hour traffic, radar alerts are of little consequence. We tested the feature and found it effective in limiting urban false alarms. Engaging the feature required 45 seconds on the first attempt and an average of 24 seconds on subsequent attempts. If the unit is moved to a

visual alerts would take forever and prove irritating in the extreme. And since an abbreviated self-test option is not offered, the driver would be subjected to this audible assault every time the car is started. We found another downside to this medley of tones: the radar and laser audible alerts are readily identifiable but the rest are almost incomprehensible. And four different laser visual alerts serve no purpose; lasers all transmit on the same frequency and to the average driver, knowing hed just been clocked by a Kustom Signals ProLaser III instead of a Laser Technology Ultralyte LR is meaningless. And the Cobra frequently gets it wrong. During testing it frequently warned variously of attacks by a ProLaser III or LTI 20-20. We were using a Laser Atlanta Speed Laser. IV. Ergonomics The Cobras four control buttons protrude far enough from the case to be easily seen. But since theyre long and slender, measuring 30mm by 6mm, and positioned in pairs at an angle, we not infrequently hit the Dim button when the adjacent City button was targeted. The IntelliMute button often was pressed instead of the Mute button for the same reason. The XRS 9300s power/volume thumbwheel switch is an elegant method of operation and the use of both reference numbers and a volume pictogram is the most effective and intuitive approach weve seen.
Cobra XRS 9300 display uses icons of different colors for band identification and a red alpha-numeric display on the far right for laser ID and numeric signal strength. The red remains visible but the pale yellow and green icons used to identify all other threats are highly susceptible to being washed-out in bright sunlight.
on each band. VII. Laser Sensitivity Laser field of view was competitive with the other units. VIII. Overall Evaluation The XRS 9300 is arguably one of the bestlooking detectors on the market. Its not, however, a particularly well designed product. Far too many audible alerts, poorly chosen visual band ID colors, industry-worst rear radar detection range, uneven radar performance and other drawbacks lead us to conclude that its one model that performs far better on the sales charts than on the road.
A bright red alphanumeric mode/signal strength display is readily visible even under difficult lighting conditions. But the yellow and pale green band ID icons are difficult or impossible to read in sunlight. Wed have to conclude that either the designers eyes interpret colors differently than ours do or they seldom drive on sunny days. This units bright chrome buttons and mesh speaker grille, coupled with its titanium-colored upper case, produced an intensely annoying reflection in the windshield directly in the drivers line of sight. This is the last detector in the world wed want to use on a long trip. V. Mounts and Hardware Unlike the other units tested which have coiled power cords, the Cobra is shipped with only a six-foot-long straight cord. The windshield mount is of good quality and keeps the unit anchored securely. VI. Radar Sensitivity At the Straightaway test site it showed excellent X-band range, ranked mid-pack on Ka band and dead last on K band, with less than half the range of the leading BEL 925. It also trailed the field on rearward Ka-band detection range, 335 feet, where it joined the Radio Shack 22-1697, at 343 feet. Curiously, at the far more difficult Curve test site the XRS 9300 fared much better, where it ranked about mid-pack

Cobra XRS 9600/9700 Subjective Evaluation
I. Physical and Operational Characteristics The Cobra XRS 9600 (and the 9700 pictured above) are built on the BG Tech large-antenna
platform. The two are identical except that the latter has voice alerts and a slight difference in the design and color of its upper case. Its text display has characters for operating mode, signal strength, laser identification and radar band identification. There are two default settings for display brightness: full bright and dim. Full-dark mode is a menu option but its unavailable in conjunction with dim and must be programmed by the user. Were puzzled that Cobra chose this complicated method rather than having a three-step display brightness control instead. Six user-selectable options are available. These include VG-2 Detect mode, Spectre I Detect mode and IntelliMute. Audio confirmation for option selections is provided. There are four operating modes: City, City X Beep Off, City X+K and Highway. City raises the threshold at which audible alerts are given. City X+K raises the threshold on K band as well. City Beep Off kills the audio entirely for X-band alerts. Highway mode acts conventionally and IntelliMute functions as it does in the XRS 9300. Programming the 9700 takes awhile. Selecting City X, for example, requires 17 seconds, including a few seconds required by the unit to store the setting and return to normal operation. This should have been grouped with City/Highway and controlled by simply pressing a button. Diverting ones attention for 17 seconds over a basic function is taking way too long. Wed surmise that whoever designed this detector is unfamiliar with the term TenTenths. (Okay, well relent. Racers use tenths to indicate how close they and the car are to the absolute edge of control. Ten-tenths is 100 percent. Someone driving at six-tenths or above on public roads is not going to have 17 seconds to tinker with a radar detector, at least not if he expects to remain crash-free.) II. Alert Systems Radar band identification is spelled out by an X, K or Ka in the text display. Signal strength is depicted by a 5-segment bar graph, by beep frequency and numerically, 1-5. There are 9 audible alerts: one each for the
three radar bands plus laser, Strobe Alert and VG-2/Spectre alert. There are also three audio tones for Safety Alert signals, one each for Emergency Vehicle, Road Hazards and Trains. Maximum audio volume averaged 76dB, second-lowest of the group. III. Features The XRS 9600 and XRS 9700 both offer a long list of features. A compass with 8 cardinal points is standard, for example, and we found it to be very accurate. Smart Power automatically shuts off the unit after a period of inactivity to prevent battery drain. Notable by its absence is tutorial mode, a feature as impractical for these models as it is for other Cobra detectors, due to their 9 audible alerts and 11 visuals. Some of the other features are of dubious value as well. Safety Alert is one. Youre more likely to get hit by lightning than to encounter a SA transmitter on the road. Worse, when we had a SA-equipped emergency vehicle come screaming up from behind, the XRS 9600 didnt spot it until the patrol vehicle was 51 feet away, making the feature useless. Strobe Alert potentially has more value but the transmitters that trigger it are used only in the city, where many drivers either dial back the audio or dont use the detector at all. The ability to spot VG-2 and Spectre RDDs is a potential winner but the XRS 9600 couldnt detect the Spectre Mk II or late model VG-2s at all. The Spectre, however, spotted the Cobra at 1,866 feet. We also noted that the XRS 9600 is susceptible to detecting other radar detectors. For example, it issued a Ka-band alert to the Whistler 1763 at 343 feet, a considerable distance. IV. Ergonomics The Cobras three top-mounted control buttons are simple to locate and easily reached. Its power/volume thumbwheel switch is an elegant method of operation and the use of both reference numbers and a volume pictogram is the most effective and intuitive approach weve seen. Yellow is a poor choice for a text display

and the XRS 9600s is no exception. In low light its fine. In direct sunlight it can be impossible to read. Equally unfortunate, the XRS 9600s bright upper housing trim and large chromed buttons generate significant windshield glare, enough that we doubt that many will mount it anywhere near their line of sight. V. Mounts and Hardware The Cobra XRS 9600 windshield mount is of good quality and locks into place for positive retention. Once in place, it keeps the unit anchored securely with minimal vibration. VI. Radar Sensitivity At the Curve test site, radar detection range was below average on X band, mid-pack on K and second from the bottom on Ka. It fared better at the Straightaway site, again trailing all but the PNI RX7500 on X band but it showed stellar K- and Ka-band range.
POP-mode performance, the overabundance of audio/visual alerts and too much windshield glare. Like the XRS 9300, its a knockout on the display shelf. On the road, its somewhat less impressive.

Cobra XRS 9600

PNI Sensoro RX7500
Cobra claims the XRS 9600 and XRS 9700 detect POP mode, the lightning-quick burst of radar generated by the MPH BEE III and a few of their hand-held guns. But the Cobra was unenthusiastic about spotting the BEE III. At point-blank 1,000-foot range it alerted only 20 percent of the time. Inexplicably, at 4,500 feet it improved slightly to 30 percent. But the dismal 25 percent average makes this unit a poor choice as a defense against POP-mode radar. VII. Laser Sensitivity Laser field of view was competitive with the other units. VIII. Overall Evaluation The XRS 9600 is one of the most stylish detectors on the market. It has a reasonable level of standard features and its Ka-band sensitivity is far better than nearly all previous Cobras, a significant achievement. In the debit column are the user-unfriendly programming method, weak text display, poor

Subjective Evaluation

I. Physical and Operational Characteristics The PNI Sensoro RX7500 can function as a cordless detector when mated to its external battery pack/windshield mount or, with power cord attached, as a corded model. (The RX7600 is identical except it has a compass.) Its LCD text display has a green backlight that operates briefly when mode is changed and during alerts. When operated in cordless mode, at night the display remains dark. There is no power-on indicator. With the unit blacked-out, theres no way to know if its working. Driving after dark with the Sensoro RX7500/7600 models could lead to unpleasant encounters. Four switches atop the case control all operations except audio volume, which is handled by a convenient slide switch on the left

cordless detectors. A tutorial mode is also standard, as is memory retention of preferred settings. IV. Ergonomics The RX7500 is a simple unit to operate but some functions operate with glacial speed. Cycling through the three filter settings requires 20.5 seconds, for instance, about 19 seconds more than wed prefer. (The BEL and Cobra required just over one second each.) Sitting at a stoplight its a non-issue. At speed, on a winding mountain road at midnight it could become a safety hazard. The primary control buttons are recessed, making them invisible when viewing the unit head-on. At night their tiny depressions must be located by touch, not particularly difficult as there are only three, but unnecessarily time consuming. Clearly this was a design decision made by a stylist, not a driver, possibly the same person who felt 74 dB of audio volume was adequate. (The typical passenger car at 70 mph has about 73 dB of ambient cockpit noise.) The units tiny dimensionssmallest cordless model on the marketare appealing until the battery box/windshield mount is added. So equipped, length nearly doubles from 3.825 in. to 7.25 in. Of more importance is the units shiny aluminum finish which generates a substantial reflection in the windshield. Since youll be depending heavily on the LCD for critical information, the intrusive glare will always be exactly in your field of view. V. Mounts and Hardware Brackets for visor and windshield (two of the latter, for use either with or without battery box) are provided. Composed of two parallel metal strips, each clips to the bottom of the case with a spring-loaded catch to secure it. There are problems with this design. Once affixed to its mount, the detector is positioned at the end of an arm thats longer than the unit itself. Even at moderate speeds it vibrates noticeably. As the speed rises, so does the amplitude until, at 70 mph on typical roads, it bounces around uncontrollably, creating a major visual distraction.
The mount employs three flimsy suction cups, one or more of which generally declines to remain stuck to the windshield on hot days, allowing the unit to suddenly flop down and dangle from the glass. On those occasions when all three work properly, an attempt to remove the assembly from the windshield often results in the battery box cover falling off and the detector separating from the mount, leaving the driver holding a handful of parts. The suction cups easily slip free of the battery box, usually leaving at least one stuck to the windshield in the bargain. A redesign might be in order here.
VI. Radar Sensitivity This model proved to be a marginal performer. At the Straightaway test site it ranked dead last on X band, with less than half the range of the leading BEL 925. It spotted the K-band radar from 14,374 feet versus 28,196 feet for the BEL 925 and 28,012 feet for the Cobra XRS 9600. It did manage to edge out the Cobra XRS 9300 (12,970 feet). On Ka band it ranked second from last at 14,115 feet, some 150 less the XRS 9300 although over 13,000 feet more than the last-place Radio Shack 22-1699s 1,047 feet. More telling was its performance at the Curve test site. Our minimum detection range at this ambush site is 1,500 feet. The PNI RX7500 delivered 932 feet on X band and 782 feet on K band (the radar had begun reading the target vehicles speed when the detector alerted). Strangely, the PNI gave 1,765 feet of warning on Ka band here, comparable to the Cobras and Whistlers. Best range: BEL 925 at 2,025 feet; worst range: Radio Shack 22-1699 at 604 feet.

VII. Laser Sensitivity The RX7500 had a 14-inch field of view, the lowest of all the units by a small margin. VIII. Overall Evaluation The RX7500 and RX7600 are basic designs, fairly easy to operate and offer the convenience of cordless operation. But they suffer from shortcomings like the absence of so basic a feature as a power-on indicator. The poorly engineered mounting system, industry-worst auto mute, faulty city mode strategy and large gaps in its performance envelope conspire to relegate it to the status of a curiosity piece. As a ticket prevention device wed suggest looking elsewhere.

on their small-antenna platform shared with the 22-1699, identical save for a slightly different case to house a compass. Three top-mounted switches control all functions save for power/volume, which is handled by a convenient, quickly adjustable thumbwheel switch on the left side. Its alphanumeric text display has yellow characters 5mm tall for operating mode, band ID and signal strength. A two-step display brightness adjustment can be made. Display Dim reduces illumination by 50 percent. Display Dark mode reduces it further 10 percent but it cannot be darkened. City/Highway, display dimming and VG-2 mode changes receive voice confirmations. Mute-function changes are marked by onebeep/two-beep tones for On and Off, respectively. Switching between City and Highway requires 2.67 seconds, including voice confirmations. One user-selectable option is available: VG2 detection on/off. A tutorial mode is offered as well. The Radio Shack 22-1697 and 22-1699 shared a trait with their BG Tech relative, the Cobra XRS 9300. All were prone to detecting the local oscillators of older BG Tech (11.812.2 GHz) models. The 22-1697 alerted to a Uniden LRD 9900SW at 104 feet, a substantial distance and almost certain to generate a false alarm on most roadways. The 22-1699 alerted at 107 feet. II. Alert Systems Radar band ID is denoted by the letters X, K or Ka and by voice alerts. Signal strength is visually depicted by one to five icons that illuminate progressively, left to right, and numerically, 1 through 9. Audible beep frequency also is used. Audible band ID is provided by tones and voice alerts. There are 11 voice messages including five for SWS: Rock Slide Ahead, School Zone Ahead, Road Narrow Ahead, Sharp Curve Ahead and Pedestrian Crossing Ahead. Of the five, only two are likely to be of much use: Sharp Curve and Road Narrow. There are two reasons for this: 1) many drivers dont use their detectors in town and wont be listening and 2)

VI. Radar Sensitivity At the Straightaway test site the Radio Shack 22-1697 showed excellent X- and K-band detection range, on par with the Whistlers, better than the Cobra and about 10 percent behind the leading BEL. However, in City mode it detected the radar from only 1,519 away, about 2,000 feet after the radar had already locked-in a speed. In comparison, the others detected it from 8,790 feet (Whistler 1734), 10,270 (BEL) and 12,831 (Cobra). The PNI did not detect X band in City mode. To be fair, City-mode X-band detection range isnt that critical a factor for U.S. drivers due to the scarcity of X-band radar. But for those who drive in states where this band continues to be used, a City mode detection scheme that so radically dials back sensitivity renders the device almost useless. True, the user should only be using City mode in urban areas, where typical radar encounters are short-range affairs, generally under 700 feet. In this circumstance the abbreviated range wont be as critical an issue, although a mile or more of warning range would give an inattentive or distracted driver more time to react. Once out on the interstate, if the driver neglects to switch to Highway mode, the unit provides too little radar range on X-band to qualify as an effective detection device. A better strategy would be to raise X-band City mode sensitivity with a consequent rise in the threshold at which audible alarms are provided. An initial audible/visual alert, followed by muted audio and a continual visual alert, would be more forgiving of operator error and provide a more useful alternative.
At the Curve test site the Radio Shack unit met our 1,500-foot minimum range on X band (1,726 feet) but failed on K band (654 feet) and Ka band (778 feet). Its rearward Ka-band range was 343 feet, some 8 feet ahead of the lastplace Cobra XRS 9300. The owner manual text of the 22-1699 model, asserting that it can detect Ka POP mode radar. Examining its package at the Radio Shack store, there was no mention of Ka POP. But we spotted it on the owner manual and purchased a unit. So we powered-up an MPH BEE III Ka-band radar to verify the POP-mode claim. What we found is that the 22-1699 cannot detect Ka POP and experiences great difficulty in detecting Kaband radar at all. It spotted the same Decatur Genesis II Select Ka-band radar as used to test the other units from only 970 feet, some 2,400 feet after the radar had locked-in a speed. VII. Laser Sensitivity At an average of 17 inches, the Radio Shacks laser performance was slightly below average. VIII. Overall Evaluation The 22-1697 and 22-1699 are representative of dozens of other BG Tech models weve sampled over the years. Large performance gaps and other anomalies account for a mediocre overall showing. And in a head-to-head comparison, their shortcomings become more evident.

signal strength. Secondary icons 2mm tall are provided for laser alerts and VG-2 detection alerts. II. Alert Systems Radar band ID icons are yellow (X), red (K) and pale green (Ka). Radar signal strength is shown numerically, 1 through 9, and by beep frequency. A yellow V indicates that a VG-2 has been detected. The latter is more cosmetic than functional as the early model VG-2 spotted the 1734 from 2,526 feet while the Whistler couldnt detect it even at point-blank range. For this reason we wouldnt recommend the Whistlers for use in areas where detector use is banned. Display brightness can be adjusted in two steps from full bright to all dark. In the latter mode only the mode icon remains lit. Alerts are audible only. Two user-selectable options are provided: VG-2 detection on/off and Battery Saverauto shutoffon/off. There are four operating modes: Highway, City, City 1 and City 2. Highway acts conventionally, City raises the threshold at which an audible alert sounds while City 1 reduces X-band sensitivity and City 2 shuts it off entirely. We found City 1 and City 2 very effective in limiting urban false alarms. Audible band ID quality is excellent with each band easy to identify. Maximum volume averaged 89 dB, lowest of the group other than the PNI 7500 but only 3 dB below the 92 dB average of the other units. The top-mounted speaker allows freedom in choosing a mounting location without compromising audio performance. III. Features


Whistler 1734
I. Physical and Operational Characteristics This platform also is used for the 1730, 1733, 1743 and 1753 Whistler models that differ only in features. The 1734 has a stylish black housing with the upper case a titanium color. Its display features 5mm-tall icons for operating mode, band ID and
Standard features include auto mute, manual mute, settings memory, SWS reception and two alternate City modes. Battery Saver mode shuts off the unit automatically after a period of inactivity to prevent battery drain. While most imported vehicles dont provide power to the cigarette lighter or auxiliary power outlets with the engine off, some American vehicles supply full-time power to both. Battery Saver will prevent a detector from draining the
battery if left on for an extended period, like sitting in an airport parking lot during a long trip. Any weary traveler whos returned late at night only to be greeted by a dead battery will appreciate this feature. IV. Ergonomics Five top-mounted buttons control the unit. Theyre wobbly to the touch and feel cheap. The slender power button doubles as the display dimming control. Its relatively easy to locate but the slim City and Quiet buttons are closely spaced and take some deliberation to find. Audio is adjusted by two more small switches, one to raise the volume, the other to lower it. This speeds up the process over the single-button BEL but its still slower than a thumbwheel switch. Cycling through all four operating modes takes 5.5 seconds, slow because the system requires a deliberate pause after each press of the button. An abbreviated self-test feature is unavailable, which means the unit runs through its full array of audio/visual alerts on each power-up, an annoying 11-second process. (Pressing the Quiet button on higher-end models kills the audio during power-up.) The Whistlers icons for City mode and Xband are yellow; those for Highway mode and Ka band are pale green. All tend to disappear in direct sunlight. K band and the numeric signal strength are red, helping them to remain visible in harsh lighting conditions. We also tested a 1773same platform, different featureswith a text display and found

Styling can have a price. Chrome on the top of a detector forms a mirror image on the glass. Before buying, ask yourself if youd like to stare at this during an all-day drive.
The metallic upper case and shiny chrome buttons of the 1743 and 1763 generated substantial windshield glare. The Cobra XRS 9300 was the only model that proved more vexing. V. Mounts and Hardware The Whistlers windshield mount is reasonably sturdy and clicks into place with a satisfying click. A side-mounted release button frees it. Like all but the BEL, it must be bent to adjust for windshield rake. However, we did find that upon removal, one of the small, lowrent suction cups inevitably slipped out of its retaining slot and remained affixed to the windshield. They also fared badly in extreme heat or cold. The two-foot-long coiled power cord is of good quality, however, and can be stretched to six feet without becoming a straight cord thereafter. VI. Radar Sensitivity The Whistlers radar scores at the Straightaway test site were very competitive. On X band it was in a virtual tie with the BELs, Cobras and Radio Shack 22-1697, all clustered at the 28,000-foot mark. On K band it tied the
that it washed out completely in direct sunlight.
This 1773s text display disappears in direct sunlight. Viewed from six inches away, this K-band alert is impossible to interpret. We finally resorted to removing the detector from the dash and holding it at eye level in an attempt to read the display.
Radio Shack at 26,659 feet, both of them following the BEL 925s 28,196 feet. Its Ka-band detection range was also excellent. VII. Laser Sensitivity Whistlers traditionally have scored well in laser tests and this one was no exception. The 1734 had the best field of view in its price range, an average of 31 inches. Strangely, it performed better than some of the pricier Whistlers by a small margin. VIII. Overall Evaluation The Whistler 1734 is one of the betterrounded imports with a comprehensive feature set, good audio and excellent laser sensitivity. Its radar sensitivity is also well-balanced, if not class-leading. It does suffer from some shortcomings in the user-friendliness category. The cheap switchgear, unpleasant windshield glare, leisurely mode changes and marginal display readability all hamper an otherwise creditable design.

VII. Laser Sensitivity The 1763s 39-inch laser field of view was substantially above average for its price class. Weve observed the same superior performance from the other models using this platform, including the 1773 and 1783. VIII. Overall Evaluation The 1763 is a reasonably well designed, competent radar detector. It has excellent audio, generally very good radar and laser sensitivitymarred by some inexplicable performance hiccupsand has an extensive portfolio of features. We find it to be aboveaverage by most key criteria and blessed with some compelling virtues. When Whistler resolves the display visibility issue and irons out a few production QC matters, it can only enhance this detectors utility and userfriendliness.

Detecting radar in flat country isnt rocket science. The microwave beam bounces off every hard surface in its path and extends in a cone that can be a mile wide at 5-plus miles of range. The test site is a two-lane county road whose roughly 3-mile-long straight sections are linked by sharp, plunging S-curves where the road crosses the same dry river bed in three locations. The straight sections arent aligned and by 20,000 feet, the detectors are pointing at about a 30-degree angle away from the radar guns. Elevation drops 300 feet over the course, further hampering sensitivity. Detectors of comparable sensitivity tend to be grouped together at the points where tiny elevation changes bring them more into line with the distant radar. At the 28,200-foot mark the road dives down yet another S-curve and takes off at a sharp tangent. No detector in our tests has ever spotted any type of radar from beyond this point.

Dark blue police Expedition lies in wait in mid-curve. By the time drivers spot the radar trap its already too late. Many detectors that delivered over five miles of Ka-band range at the Straightaway test site failed miserably here, not alerting until a target speed was already locked-in. Our minimum detection range for all three frequencies: 1,500 feet.
