The Garmin GT8HW-TM is built for anglers who fish shallow water and need precise bottom definition along with wide, well-separated fish arches. Its high wide band CHIRP sonar sweeps continuously across 150–240 kHz, delivering crisp target detail across a beam angle up to 24 degrees — a broader coverage footprint than standard-width transducers. Rated at 250 W and terminating in an 8-pin connector, this plastic-body transducer mounts on either the transom or a trolling motor, making it a versatile fit for a range of boat setups.
