WideSide Sonar
(with Optional-Purchase WideSide Transducer)
Your Matrix 97 Fishing System also supports WideSide sonar with the purchase of an additional
WideSide transducer. The WideSide transducer is a specialized "side-looking" transducer that is
extremely useful for bank fishing or looking for bait fish in open water. The WideSide transducer uses
three different sonar elements that transmit signals to the left, right and straight down from your boat.
The downward beam is 200 kHz with a 24° area of coverage. This beam maintains a continuous digital
depth readout from the bottom directly beneath your boat. The side beams are 455 kHz with a 16° area
of coverage. The side-looking elements can be used independently, or together to locate targets near
the surface of the water on either side of your boat.
How GPS and Cartography Work
Your Matrix Fishing System uses GPS and sonar to determine your position, display it on a grid, and
provide detailed underwater information. The Global Positioning System (GPS) is a satellite navigation
system designed and maintained by the U.S. Department of Defense. GPS was originally intended for
military use; however, civilians may also take advantage of its highly accurate position capabilities,
typically within +/- 10 meters, depending on conditions. This means that 95% of the time, the GPS
receiver will read a location within 10 meters of your actual position. Your GPS Receiver also uses
information from WAAS (the Wide Area Augmentation System), EGNOS (the European Geostationary
Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are
available in your area.
GPS uses a constellation of satellites that continually send radio signals to the earth. Your present
position is determined by receiving signals from up to 12 satellites and measuring the distance
from the satellites.
The GPS Receiver included with your Matrix Fishing System allows you to combine easy-to-use
FishingGPS™ chartplotter and navigation capabilities with advanced fishfinding. The following
GPS functionality is currently supported by the Matrix Fishing System when it is connected to the
included GPS receiver:
• View current position
• View current track (breadcrumb trail)
• View precision speed and heading from your GPS receiver
• Save tracks, waypoints and routes
• Travel a route and navigate from one waypoint to the next.
