Keterangan :

GPS FISHFINDER 178C adalah gps yang terintegrasi dengan sonar. Disamping kita mendapatkan data posisi, kita bisa juga bisa mengetahui keadaan dibawah laut. Dilengkapi dua mode tranducer single dan dual frekuensi.
GPSMAP 178C Sounder features

* 320 x 320-pixel, 256-color CSTN screen with adjustable CCFL backlight
* 3.2" H x 3.2" W (4.5" diagonal) viewing area
* 4.9�H x 6.3�W x 2.8�D unit dimensions
* State-of-the-art 200 MHz processor makes data acquisition, panning, and zooming virtually instantaneous
* Choose either a dual-frequency 50/200 kHz transducer for offshore boating or a single-frequency 200 kHz transducer for inland lakes and bays
* See-Thru® technology (which separates fish from thermoclines and structure) and Depth Control Gain (DCG®) for detailed images of structure and bottom densities
* New digital display technology offers an easy-to-read, semi-transparent digital readout that allows users to see sonar images "behind" the data
* User waypoints are automatically tagged with the date and time of creation, as well as water temperature and depth—vital information for serious anglers
* 10,000 active track points and 700 saved track points; database information can be stored on removable data cards and transferred to a PC or another unit
* Sends, receives, and displays positioning data with DSC equipped VHF radios
* TracBackâ„¢ mode helps guide you back to points along a route
* Tracklines can be color-coded for trolling or cruising applications
* 500-watt (RMS) 4000-watt (PTP) output with dual-frequency transducer
* 400-watt (RMS) 3200-watt (PTP) output with single-frequency transducer
* Adjustable range, gain, zoom, and bottom lock
* Temperature log maintains a graphical record of temperature data
* Shallow-water, deep-water, fish-by-size, timer, low-battery-voltage, anchor-drag, arrival, off-course, proximity-waypoint, and clock alarms
* Water temperature and fish ID with depth alarms
