Detailed description
Detailed description
Designed for fiberglass hulls of bass boat-style boats, the Garmin GT8HW-IH transducer is an in-hull solution that provides reliable depth readings even at high speeds. This model uses traditional CHIRP technology with a wide beam (High Wide) for clear underwater coverage and optimized target separation.
Performance and integration
The GT8HW-IH operates over a frequency range of 145 to 230 kHz with 250 W RMS power, enabling detection up to 244 meters (800 feet) in freshwater. Its 24° to 16° beam provides effective bottom coverage. Unlike transom-mount transducers, the in-hull installation of the GT8HW-IH eliminates cavitation issues and damage risks, which is particularly advantageous for high-speed vessels or those frequently trailered.
Compatibility and scalability
Compatible with many Garmin chartplotters from the ECHOMAP and GPSMAP series, this 8-pin transducer integrates easily with existing systems. For added versatility, it can be paired with a GT30-TM transducer (transom-mount) via an optional Garmin Y-cable (010-12445-33). This setup allows combining the GT8HW-IH’s high-speed depth readings with ClearVü/SideVü scanning capabilities at trolling speeds. The transducer comes with a self-adhesive foam mounting ring for easy installation.
