GPSMAP 235 Sounder

gpsmap_235_sounder.jpg (12643 octets)The GPSMAP 235 Sounder offers the advantage of an innovative depth sounder and the proven performance of GARMIN GPS chartplotting in a single, easy-to-use package.

GARMIN's 235 depth sounder is packed with a combination of features you won't find any other sounder. Dual frequency operation gives you the clearest possible image in both deep and shallow water.

Powerful noise rejection effectively removes the most stubborn cross talk and interference. Over 25 square inches of active viewing area gives you sizeable detail coverage. A variable zoom window allows you to view increased detail at the touch of a button. You can even mark underwater waypoints to capture the position and depth of objects like reefs, dropoffs or hazards, to permanently store them for future use. Combine these innovations with a wide range of additional advanced features, and it's easy to see that the GPSMAP 235 Sounder is designed to give you all the information you need.

If having the best depth sounder on the market isn't enough, add navigational guidance that is second to none.

The GPSMAP 235 Sounder features GARMIN's high performance 12 parallel channel GPS receiver for unmatched accuracy and G-chart™ digital cartography for chartplotting on inland or offshore waters.

  • Crisp, 4-level grayscale display and GARMIN's exclusive See-Thru™ technology separates black fish returns from the light gray returns of thermoclines and structure.
  • One-touch instant zoom rescales entire screen, while 2X and 4X oversampling provides greater detail of the bottom.
  • Innovative split screen display GPS cartography and sounder data simultaneously.
  • Graphic whiteline display with Depth Controlled Gain (DGG™) feature always presents a clear image of bottom hardness, structure, and thermoclines not found in other fishfinders.
  • Excellent sounder dynamic range for viewing weak signals in the presence of strong signals.
