If finding a replacement transducer(for a second boat or something): Make sure you can verify it has the 18 pinout and power connections that the 140 comes with.

Owned for about 3 years. Works fine. Never had a problem. Well built unit. Solid. Just purchased a 2nd one

Garmin 140


The Garmin 140 was easy to install, Has a better electrical connection than the Hummingbird. That was the main reason for changing to the Garmin. I would recomend it.

Product Specifications

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. 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. 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.
