Airmar M135C-M-9N xSonic M135m Medium CHIRP 1kW In-Hull Transducer 9-Pin

The Airmar xSonic M135m is a high-performance medium-frequency CHIRP in-hull transducer designed for serious anglers and mariners who demand exceptional depth penetration, wide coverage, and crisp target separation — all without drilling through the hull. Connecting via a 9-pin connector, the M135m is compatible with a wide range of chartplotters and fishfinders from leading MFD manufacturers.

Key Features:

• Medium CHIRP Frequency: Delivers the ideal balance of bottom coverage beneath the vessel, extended depth range, and the ability to produce clean, accurate target arches in the water column
• 1 kW Power Output: High-power transmission for reliable performance in deep-water and offshore applications
• In-Hull (Shoot-Through) Installation: Mounts inside the hull using an oil-filled or water-filled housing — no hull penetration required, reducing the risk of water intrusion and simplifying installation
• xSonic Technology: Airmar's advanced transducer element design optimizes signal clarity and sensitivity across the CHIRP sweep range
• 9-Pin Connector: Compatible with major MFD brands including Garmin, Raymarine, Lowrance, and others (adapter cables may be required)
• Durable Construction: Built to Airmar's marine-grade standards for long-lasting performance in saltwater and freshwater environments

The M135m's medium-frequency CHIRP sweep provides the right combination of target resolution and depth penetration, making it an excellent choice for offshore bottom fishing, deep-water trolling, and general marine navigation. Its in-hull design makes it particularly well-suited for fiberglass hulls and installations where through-hull mounting is not practical.
