The ultimate in special purpose sonar fishing systems is here. What makes the FL-22 so special is the technical breakthrough of matching the power output and pulse length to the depth you are fishing. In less technical terms, the FL-22 is the first flasher sonar system that matches the depth range you've set to the resolution on the display so you see every possible detail in the water below. The FL-22 delivers the best target ID and target separation of any sonar system ever made! A unique feature of the FL-22 is the six 10 foot increment range settings, with a maximum depth of 60 feet. The idea of having the available depth range matched to the actual water depth being fished can greatly increase display resolution making it easier to work lures and see when a fish is interested. The popular night fishing mode is also featured in the FL-22. By cutting the brightness of the display by 50%, you are able to comfortably view the display in complete darkness without affecting your night vision. The FL-22 offers two Auto Zoom zones, one for the bottom six feet and the other for the bottom twelve feet. For super-shallow water fishing, a low power mode is built-in. The FL-22 even has a Bottom Lock feature for open water use. This locks the zoom on the bottom six feet no matter how much the water depth changes. All these features—still controlled with only three, easy to reach knobs—make the FL-22 the most advanced sonar system ever offered by Vexilar.
