Introduction to Navigation
Use the Matrix Fishing System to establish waypoints at areas of interest and to navigate to those waypoints via a saveable route (representing the shortest intended distance between waypoints). You can also view and save tracks, which represent the actual path of the boat.
Waypoints, Routes and Tracks
Waypoints are stored positions that allow you to mark areas of interest or navigation points. Your Matrix Fishing System can store up to 750 waypoints.
Waypoint XTE: Cross Track Error. Distance of Boat from Route DTG: Distance to Go to Waypoint Water Surface Temperature Speed of Boat
Route Track BRG: Bearing to Waypoint Bearing of Boat with Respect to True North
Routes link two or more waypoints together to create a path for navigation, and are used in trip planning. You can link individual waypoints together by using the GOTO key. A route represents your intended navigation and shows the shortest path from each waypoint to the next. As you travel a route, staying on the route line is the most efficient way to get to your destination, although you should always look out for obstacles not shown on the chart. Your Matrix Fishing System can store up to 10 routes that can each contain up to 20 waypoints. Tracks consist of detailed position history, and are displayed as a breadcrumb trail of trackpoints. The Current Track shows the position history since the unit was powered up (maximum of 2000 trackpoints displayed). You can clear the Current Track or save it at any time. Your Matrix Fishing System can store up to 10 saved tracks, each containing 2000 trackpoints. The current track represents your actual path so far.
Save, Edit, or Delete a Waypoint
Save your current position as a waypoint: On any view, press the MARK key to save the current position of the boat as a waypoint. Save the cursor position as a waypoint: On the Chart or Combo view, use the Cursor key to designate the position you want to save as a waypoint. Then press the MARK key to save the marked position as a waypoint. Save a position from the sonar history: On the Sonar view, use the Cursor key to point to a feature in the sonar history (also called the Sonar Saver feature). Press the MARK key to create a waypoint at the location where that sonar reading was taken. The new waypoint will also record the depth at that location.

NOTE: When you save a waypoint by any of these methods, a numerical waypoint name is automatically assigned. You can edit the waypoint information later to give it a different name and select an icon to represent it (see Waypoint submenu on the Navigation Main Menu Tab).
Display the Waypoints Submenu: From any view, press the MENU key twice to display the Main Menu System, then use the RIGHT Cursor key to select the Navigation tab. Select Waypoints and press the RIGHT Cursor key to display the Waypoints submenu. Program a specific position as a waypoint: To create a waypoint that is NOT your current position, from the Waypoints submenu, select the Create option and press the RIGHT Cursor key. Use the Cursor keys to program a waypoint name, latitude, longitude, and icon before selecting Save. Edit a waypoint: From the Waypoints submenu, select Edit and press the RIGHT Cursor key to display a list of saved waypoints. Select the waypoint you want to edit and press the RIGHT Cursor key. Use the 4-WAY Cursor Control key to move from field to field, and the UP and DOWN Cursor keys to changes values once you are in a field. In the Waypoint Name, Latitude and Longitude fields, use the UP and DOWN Cursor keys to change the letter or number. All upper and lower case letters are available, as well as digits 0-9 and some punctuation characters. In the Waypoint Icon field, use the UP and DOWN Cursor keys to change the icon used to represent the waypoint on the Combo and Chart Views. You can exit these fields with the LEFT and RIGHT Cursor keys or by pressing the EXIT key. Select Save and press the RIGHT Cursor key to save your changes. To make it easier to select a waypoint, select Sort By and press the RIGHT or LEFT Cursor keys to select a sort order: Name shows the waypoints alphabetically Time shows the most recently-created waypoint first Distance shows the closest waypoint first.
Delete a waypoint: From the Waypoints submenu, select Delete and press the RIGHT Cursor key to display a list of waypoints. Select the waypoint you want to delete, then press the RIGHT Cursor key. You will be asked to confirm deletion before the waypoint is actually deleted.
Navigate to a Waypoint or Position
Navigate to the cursor position: From the Chart or Combo view, use the Cursor key to select a position or waypoint to which you want to navigate. Press the GOTO key. Navigation will begin immediately. Navigate to a specified waypoint: Press the GOTO key, then choose the waypoint to which you would like to navigate from the waypoint list and press the RIGHT Cursor key to select it.

NOTE: By repeating the previous instructions, you can add more waypoints to create a longer multisegment route.
Skipping a waypoint: From the Navigation X-PressTM menu, select Skip Next Waypoint and press the RIGHT Cursor key. If there is not another waypoint to skip to, navigation will be cancelled. Cancel navigation: From the Navigation X-PressTM menu, select Cancel Navigation and press the RIGHT Cursor key. Canceling navigation removes the route and any waypoints created using the GOTO key, but does not remove any saved routes from memory. You will be prompted to save the current route when you cancel navigation.

The control head loses power at high speeds.

Possible Cause

If the power output of your boats engine is unregulated, the control head may be protecting itself using its over-voltage protection feature. Make sure the input voltage does not exceed 20 Volts. The transducer position may need to be adjusted. A mix of air and water flowing around the transducer (cavitation) may be interfering with the inter-pretation of sonar data. See your Installation Guide for suggestions on adjusting the transducer position. Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.
When the boat moves at higher speeds, the bottom disappears or suddenly weakens, or the display contains gaps.
There are no fish detected, even when you know they are in the water under the boat, or sonar readings seem weak or faulty.
Sonar readings may be affected if the transducer is not positioned correctly (i.e. mounted at an angle, not straight down), or there is some kind of mechanical interference, either because it is mounted inside a hull that is too thick for proper sonar transmission, the bond between the transducer and the hull is not airtight, or because the transducer is dirty. Check with your Installation Guide for guidance on re-positioning the transducer, and make sure the transducer is clean. Low battery voltage may be affecting the power of signal transmission. Electrical noise from the boats engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.
Finding the Cause of Noise
Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity readings. One or more of the following sources can cause noise or interference: Possible Source of Noise Isolation
Other electronic devices Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time to see if the noise re-appears. To determine whether the boats engine is the source of the noise, increase the RPMs while the boat is in neutral and stationary to see if the noise increases proportionately; if noise appears when you rev the engine, the problem could be the spark plugs, alternator, or tachometer wiring. Replace the spark plugs with resistor plugs, install an alternator filter, or route the control head power and transducer cables away from the engine wiring. Turbulence created by the propeller can cause noise; make sure the transducer is mounted at least 15 (38 cm) from the propeller, and that the water flows smoothly over the face of the transducer at all times.
