It's only about the size of a flashlight, but this pocket-sized digital sonar is a powerful instrument, with an oversized LCD display and a transducer beam capable of displaying depths to 299 feet. The LX-i Handheld is equipped with a built-in fish alarm, which will alert the angler of fish within the sonar's 12-degree cone angle. Reads depth in increments to a tenth of a foot. No need to drill dozens of holes looking for structure, just press the LX-i against the ice and take a reading. 2,500 watt output power for shooting through ice or obtaining depth readings from canoes or bellyboats. Additional features include an automatic shut-off to help save battery life, CR-P2 6V lithium battery, low battery indicator, and soft carry case. 20 hours of continuous runtime. Made in USA.
