Fish Finder
This is a dual frequency fishfinder that operates at 50 and 200 kHz. Cone angle coverage is 35° and 12° respectively. Maximum depth of 1500 feet or 457 m is achieved at the low frequency 50 kHz and 35° cone angle. This requires power output of 4000 W peak-to-peak or 500 W RMS. Of course, maximum depth is a function of water conditions, sonar installation, and sonar settings.
Fish Finder Features
Sonar readings continuously display fish activity and bottom contours and can be set for automatic ranging to simplify navigational chores. The unit constantly tracks bottom or sections of the water column manually. A zoomed sonar view or GPS maps can be observed using split screen mode. A surface water temperature sensor is built into the transducer so that temperature readings can be displayed.
GPS Receiver
The external antenna EGC – 12w and receiver use 12 parallel channels to track orbiting GPS satellites and with inbuilt WAAS capability to further enhance coordinate accuracy.
Memory
Up to 1 GB of mapping memory is available to upload maps or store information. Maps can be imported through an MMC card or SD card. Sonar records and sonar settings can be stored in built-in memory for later access.
