Advanced In-Hull CHIRP Transducer for Offshore Performance

The Airmar M422C-LH Transducer is engineered for serious offshore anglers and boaters who demand superior deep-water target detection without any external protrusions from the hull. Designed for solid fiberglass hulls up to 30 feet, this in-hull, dual-frequency CHIRP transducer ensures high-precision depth readings even in the most challenging marine environments.

With powerful 1.5 kW output and CHIRP technology operating across a wide frequency range—low (47-52 kHz) and high (190-210 kHz)—the M422C-LH delivers exceptional deep-water performance up to 2000 feet (610 meters). Whether navigating offshore or fishing at extreme depths, this transducer provides clear, accurate sonar readings without compromising hull integrity.

High-Powered CHIRP Sonar Performance

Built to maximize offshore fishing and navigation, the M422C-LH offers a wideband high-frequency range for superior target separation and a low-frequency range for extended depth capabilities. The 18-degree beamwidth at low frequency and 5-degree beamwidth at high frequency ensure optimal coverage, making it a versatile choice for varied marine applications.

Innovative In-Hull Mounting Design

Unlike traditional through-hull or transom-mounted transducers, the M422C-LH is secured inside the boat’s hull using a specialized urethane housing filled with eco-friendly antifreeze. This unique design allows sound waves to transmit seamlessly through solid fiberglass hulls, maintaining exceptional sonar performance while eliminating drag or the risk of damage from underwater obstacles.

The in-hull installation also makes this transducer ideal for boats that are frequently trailered or lifted, as it requires no hull modifications or external mounting brackets.
