The Fishfinder 90 combines simple operation 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 90'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 a clear black and white display and bright backlight, the Fishfinder 90 has one of the sharpest screens for the money.

+ See Fish Clearly
Fishfinder 90 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.
