Garmin Fishfinder 320C with Dual Frequency Transducer DISCONTINUED

The color display on the Fishfinder 320C helps make this sounder a more powerful tool. In this screen, we can see a very distinct creek channel displayed at the bottom of a reservoir. The outline of a brush pile - about eight feet off the bottom - is shown in red. The returns around the brush pile are schools of shad and game fish. The fish returns that have red or green in them mean the fish were large enough to provide a solid return.

The Fishfinder 320C's zoom feature increases the detail of what's below. This screen shows the unit zoomed by 2x, which allows us to see the detail around a stump. The red areas indicate the best sonar returns. The stump shows up in red, and there appear to be several fish holding close to it. Lighter-blue returns indicate weaker signals (most likely schools of shad). The Fishfinder 320C allows you to zoom in 2x or 4x on either a split or full screen for amazing detail and definition at any depth.

On this screen, we can see schools of bass or crappie in and around the stumps of a reservoir. Color fishfinders like the Fishfinder 320C give you the ability to see the intensity of returns. The hard bottom is red, as are the solid sonar returns of fish and bait fish. Less dense objects, such as weeds or mud, show up blue or green. This makes it easier to determine the bottom consistency.

This screen shows how you can use the zoom function of the Fishfinder 320C in a split-screen fashion. With two levels of zoom, the Fishfinder 320C has amazing detail that can be seen simultaneously with no zoom at all. The user also has the option of blue, black, or white background settings. This screen shows the unit with the background set to black.

This screen shows how a user can control the Fishfinder 320's alarms in order to alert them of fish, shallow water, deep water, drift, and water temperature.
