The Garmin GT8HW-IF sensor is ideal for ice anglers who want clear bottom clarity under ice and crisp, transparent and wide bows with excellent target separation. The wider beam width-up to 24Ã‚Â° beam angle-provides greater coverage in the water. The 4-pin sensor has a high-bandwidth CHIRP traditional sonar (150-240 kHz) and a rated power of 250W. The shape and beam width of the transducer have been optimized for ice fishing, and have a silicon-coated cable that is still flexible in harsh winter conditions. The maximum depth is 800'.
