The Fishfinder 140 combines a 4-inch grayscale display and Garmin’s exclusive fishfinder technology into an entry-level sonar that's perfect for any vessel where space is at a premium.
Pinpoint Your Next Catch
Fishfinder 140's included dual-beam transducer provides excellent shallow-water performance, and the wide viewing angle lets you see fish even off the sides of the boat. With an easy-to-ready grayscale display and backlight, the Fishfinder 140 has one of the sharpest screens for the money.
See Fish Clearly
Fishfinder 140 also offers Ultrascroll™, which refreshes the screen with lightning speed so you always see the most up-to-date information. You can manually adjust the gain or set to Auto Gain, which adjusts the level of detail you see automatically.
