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 your display.

See maximum depth performance to 1,200’ in freshwater.

Access CHIRP sonar frequency range from 85–165 kHz.

Search with beamwidths of 16–24 degrees.

Count on fast-response water temperature sensing.

Thru-hull design offers flush installation with 0-, 12- or 20-degree tilt.

Auto-ID enables simple plug-and-play operation.

MIDBAND CHIRP TRADITIONAL 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 800’ in saltwater and 1,200’ in freshwater.

BROAD FREQUENCY RANGE

Use the perfect frequency for the waters you’re fishing. 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 your 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 fiberglass, 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.
