Garmin Fishfinder 90

The Fishfinder 90 wraps simple operations and Garmin’s exclusive fishfinder technology into an entry-level sonar. It’s perfect for any vessel where space is at a premium. Dual-beam transducer operation gives you better shallow-water performance. The wide viewing angle (60°) lets you see fish even off the sides of the boat. With a basic black-on-white display, the Fishfinder 90 has one of the sharpest screens for the money.

The Fishfinder 90 also offers Ultrascroll™ which allows boaters to get a much faster refresh rate on their sonar display. AutoGain, as well as user adjustable gain, is also standard on all of Garmin’s new fishfinders.
