- 320 x 320-pixel, 256-color CSTN screen with adjustable CCFL backlight
- 3.2" W x 3.2" H (4.5" diagonal) viewing area
- 6.3" x 4.9" x 3.7" (W x H x 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
- TracBack™ 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
