Includes display backlighting and a pulse-lit advanced sensor for night fishing. All controls are easily commanded from the waterproof wrist unit. Remote sensor runs 500 continuous hours, and automatically shuts off after removal from water. With instruction manual and remote sensor. Sensor is ABS plastic. Battery included. 2" H x 2" W x 2 3/4" D. (1 oz.)
