Midband Chirp Traditional Sonar

This 8-pin 1 kW stainless steel thru-hull transducer features high-definition mid-band CHIRP sonar that clearly defines fish targets and structures down to 1,800’ in saltwater and 2,400’ in freshwater.

Broad Frequency Range

Use the perfect frequency for the waters in which users are fishing. Covering the medium frequency range, this transducer pulses from 80–165 kHz, displaying a wide coverage area, clear 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 the compatible chartplotter display.

Thru-Hull Installation

A durable stainless steel 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, steel, aluminum, and wood, the transducer is available in a range of tilt versions to accommodate deadrise angles of 0–24 degrees without a fairing block.
