Suitable for both freshwater and saltwater, the Fishfinder 250c is available with either a dual-frequency 50/200 kHz transducer for deep-water applications, or a single-frequency 200 kHz transducer for shallow inland lakes and bays.

All configurations feature Garmin's patented See-Thru technology which separates fish from thermoclines and structure and Depth Control Gain (DCG), for detailed images of structure and bottom densities. Additionally, anglers can connect a Garmin GPS receiver (sold separately) to the unit to mark underwater waypoints directly from the Fishfinder's keypad.

The Fishfinder 250c's slim profile also makes it ideal for mounting in-dash or on the bow. Its quick-release, one-knob tilt swivel mount allows for easy viewing of its 4.5-inch, 320 x 320 pixel, 16-color display at any angle.
