Expect huge performance in a compact size with the new Humminbird 363 fishfinder and GPS. This little dynamo features advanced DualBeam PLUS sonar and ultra precise 16 channel GPS/WAAsS receiver with a built-in UniMap? to show your location virtually everywhere you go. You even have flexibility on where to mount it. The 300 Series models mount in-dash just like many factory installed models, or using our exclusive Tilt & Swivel Quick Disconnect Mounting System. And while they?re built for tight spaces, we didn?t skimp on the performance. They?re loaded with prograde technology such as Real Time sonar for rapid updates and Sonar Echo Enhancement for the highest degree of sensitivity.
