For portable freedom when fishing, check out Hawkeye's newest all-in-one, versatile fishing tool, the Handheld Sonar System FX. This featherweight, floatable, waterproof tool employs Side-Scan Fish-Detecting Sonar, which scans an area for drop-offs, ledges or hiding fish within 199 feet with the press of a button. Before making a cast, pinpoint the presence of hiding fish, which are clearly indicated on the SilverScreen backlit LCD display. According to the company, the HawkEye's algorithmic programming has created a smart system that only displays correct readings, even when using HawkEye's shoot-thru technology, which allows readings through ice or boat hulls. You won't have to stop fishing when the sun goes down - illuminating the high-output Xenon flashlight attracts fish while night fishing and helps you find channel markers at night while boating. The high-impact, sure-grip rubberized housing is slip-free, impact resistant and marine tough. The bargain-priced FX allows easy, one-touch access to user features with its auto-centering flip switch. $139.99.
