Less Time Finding, More Time Fishing

Designed for reduced drag and optimum sonar performance on midsize fishing and cruising boats, this flush-mounted, 350-watt midband CHIRP transducer clearly defines fish arches, structure and bottom depth returns on the display.

Midband CHIRP tradional sonar – This 8-pin, 350-watt bronze thru-hull transducer features high-definition midband CHIRP sonar that clearly defines fish targets and structure down to 240m in saltwater and 365m in freshwater.

Broad frequency range – Use the perfect frequency for the waters. Covering the medium frequency range, this transducer pulses from 85-165 kHz, displaying a wide coverage area, crisp fish arches and accurate depth readings.

Optimum ping sensitivity – Offering excellent sonar sensitivity, low noise, high resolution and good separation of targets, this robust transducer makes it easier than ever to distinguish fish and structure on a compatible chartplotter display.

Thru-hull installation – A durable bronze housing and stem offer straightforward thru-hull flush mounting for minimum drag and optimum beam orientation for clear sonar returns.

Auto-ID technology – Enjoy simple plug-and-play operation with Garmin auto-identification technology – which enables the sonar to automatically configure itself to the transducer being used.

Fits various hull types – Configurable for a wide variety of boat hull materials, including fibreglass, composite and wood, the transducer is available in a range of tilt versions to accommodate deadrise angles of 0-20 degrees without a fairing block.
