Even in a world chock-o-block full of digital marvels, the H22FX flashlight stands out as one nifty piece of equipment. Waterproof and powered by four AA batteries, the LED-powered light not only measures water temperature to within a tenth of a degree, it also takes soundings to a depth of 200 feet. To use, simply place the sonar sensor, which is located alongside the LEDs at the front of the flashlight, into the water or allow it to “Shoot-Thru” the bottom of your boat’s hull. The depth will then appear in a display in the handle at the flip of an activation switch.
