The sleek profile of the FL-20 offers a larger viewing window and a greatly enhanced viewing angle of the display. The super-bright LEDs can be easily seen in sunlight, but after dark, the FL-20 offers a night mode so you can turn down the intensity of the lights for comfortable night viewing.

The FL-20 uses the same easy to operate, three-knob control system as their popular FL-18 Flasher sonar, but with some enhanced features. A ten step inference rejection feature is standard with the FL-20. You will also be glad to know the Vexilar FL-20 enhanced receiver performance and increased noise immunity. This means less inference when fishing with other 200 kHz systems. The FL-20 boasts two auto zoom ranges that split the display screen to let you focus in on just the bottom 6 or 12 feet of the water column, depending on your needs. The FL-20 is capable of showing target I.D. of less than 1/2 inch, but can also display depths down to 200 feet.

Another new feature is a 20 foot shallow water mode that is available for anglers when fishing in thick weeds or in very shallow water. The 20' Low Power Mode cuts the output of the transmitter by nearly 50% to make it easier to see true bottom in thick weeds or when you are fishing in only a few feet of water. Combine all these features plus a low battery warning light and you can see why many experts believe the FL-20 will change the way many anglers fish with sonar summer or winter.
