Description
Airmar M135M In-Hull 1kW CHIRP Transducer | Boat Supply Store
For boaters seeking precise underwater clarity without hull penetration, the Airmar M135M offers 1 kW of power for significant depth penetration up to 457 meters (1500 ft). Its medium CHIRP frequency range of 85-135 kHz provides exceptional bottom detail and fish separation, making it ideal for structure identification in mid- to deeper water applications. This in-hull design is specifically engineered for solid fiberglass hulls, preserving a clean exterior profile and minimizing drag, a key advantage for trailered or lifted vessels.
Key Features
- 1 kW power for deep-water penetration and target resolution.
- Medium CHIRP sonar (85-135 kHz) for optimal fish and bottom detail.
- In-hull mount preserves hull integrity and provides a clean exterior.
- 457m (1500ft) maximum depth capability for extensive coverage.
- 16-11 degree beamwidth offers a balance of coverage and detail.
- Patented Xducer ID® technology for easy integration and diagnostics.
- Designed for solid fiberglass hulls up to 22 degrees deadrise.

Common Concerns Answered
What if my boat has a cored fiberglass or metal hull?
The Airmar M135M is specifically designed and optimized for solid fiberglass hulls. It is not compatible with cored fiberglass or metal hulls due to the way the sonar signal interacts with these materials.
Is this transducer difficult to install myself?
Installation requires precise measurements, careful hull preparation, and accurate angle adjustment to ensure optimal performance. Many boaters opt for professional installation due to these critical steps. The use of a coolant within the mounting base also requires specific attention.
How does the Airmar M135M compare to transducers with Side or Down Imaging?
The Airmar M135M focuses on traditional CHIRP sonar for excellent depth penetration and fish identification. While it does not offer Side or Down Imaging capabilities, its 1 kW power and medium CHIRP frequencies provide superior detail in deeper water where these other technologies may be less effective or have reduced range.
