The Garmin GT8HW-TM delivers High Wide Band CHIRP sonar across a continuous 150–240 kHz sweep, producing sharp bottom detail and well-separated fish arches in shallow-water conditions. A beam angle up to 24 degrees provides a broader coverage footprint than standard-width transducers, while the 250 W power rating and 8-pin connector keep it compatible with a wide range of Garmin displays. The plastic body mounts on a transom or a trolling motor, giving you flexible installation options across different boat configurations.
