The Wrist Strap Fish Finder

This fish finder's display is worn on your wrist, letting you move freely as you angle, unlike other sonar sensors with screens that must be handheld or affixed to a boat. It operates in a wide 75' remote radius, transmitting real-time views of fish and underwater terrain to the 1 1/4" LCD display. The sensor reads depth to 120' with a wide 90º sonar beam and also measures water surface temperature. Includes display backlighting and a pulse-lit advanced sensor for night fishing. All controls are easily accessed from the waterproof wrist unit that doubles as a wristwatch. The ABS plastic remote sensor runs 500 continuous hours, and automatically shuts off after removal from water. CR-2450 battery for wrist display included. 2" H x 2" W x 2 3/4" D. (1 oz.)
