Airmar B75M Bronze Chirp Thru Hull 20° Tilt - 600W - Requires Mix and Match Cable

The Airmar B75M Bronze Chirp Thru Hull 20° Tilt transducer delivers professional-grade sonar imaging for fishing vessels, research platforms, and serious anglers who demand precise underwater visibility. Operating at 600W with CHIRP broadband frequency transmission, this bronze transducer achieves bottom detection to 3,000 meters (10,000 feet) with 5 to 10 times greater detail and resolution than single-frequency alternatives, enabling operators to distinguish between fish species, structure, and bottom composition with exceptional clarity.

The 20° tilt mounting angle accommodates hull geometry while optimizing beam projection for offshore and nearshore applications. Bronze construction resists corrosion in saltwater environments, a critical consideration for transducers exposed to continuous marine exposure. CHIRP technology sweeps across multiple frequencies simultaneously, dramatically improving target separation and reducing noise interference—essential when operating in challenging conditions like kelp beds, heavy thermoclines, or cluttered bottom structure. This transducer requires a Mix and Match cable assembly, allowing integration with existing Airmar-compatible sounder systems from leading marine electronics manufacturers.

The B75M is built for commercial fishing operations, charter captains conducting client surveys, and tournament anglers competing at the highest levels. Weekend boaters upgrading from basic single-frequency transducers will immediately recognize the advantage in object definition and seabed mapping. The 600W power output ensures strong signal transmission even in deep water, while CHIRP's frequency-sweep design penetrates challenging bottom types without compromising image resolution. Bronze materials and thru-hull construction represent an investment in long-term reliability rather than a budget component.
