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.
