Garmin
Fishfinder 320C

Features include:

• Five-inch (diagonal), 16-color TFT display that's viewable in direct sunlight
• User-selectable settings for overcast, sunny, and nighttime viewing
• Simple sonar interface, with vital information on depth, zoom, range, frequency, and gain one touch away
• Depth Control Gain (DCG®) automatically adjusts sonar sensitivity by depth and delivers a highly detailed image of bottom structure
• See-Thru® technology separates fish returns from thermoclines and underwater structure to remove the guesswork in interpreting fish arches
• Bottom lock gives anglers a constant view of the bottom within a user-configured depth parameter (e.g., viewing all activity from 40 feet down to the bottom)
• Temperature log graphically records temperature data
• GPS repeater allows communication with a Garmin GPS, so anglers can use the remote waypoint-marking feature to send a specific location
• Unit can be ordered with a single-frequency (200 kHz) transducer, dual-fequency (200/50 kHz) transducer, or display only (if you have a Garmin transducer already installed). Please see your local dealer for the version that's right for you.
