Airmar B75C-20-HW-MM CHIRP Thru-Hull Transducer 20° Tilt 600W 150-250kHz

The Airmar B75C-20-HW-MM is a low-profile CHIRP-ready thru-hull transducer designed for center consoles and smaller vessels requiring high-performance fish finding in shallow to moderate depths. This single-band high-frequency transducer combines exceptional target separation for baitfish and schooling gamefish with a wide 30° beamwidth that maximizes underwater coverage.

High-Frequency CHIRP Performance:

Operating across the 150-250 kHz high-frequency band, the B75HW delivers up to 100 kHz of total bandwidth, providing outstanding bottom detail, superior target resolution, and clear fish returns in depths up to 106 meters (350 feet). The 600-watt power rating ensures strong echo returns even at speed when properly installed.

Tilted Element Design:

The B75HW features a fixed 20° tilted element specifically engineered for hulls with 16° to 24° deadrise angles. This tilt compensates for hull angle by directing the sonar beam straight down, ensuring maximum echo strength and accurate depth readings. The transducer mounts nearly flush to the hull for minimal drag and excellent high-speed performance.

Key Features:

• CHIRP-ready single-band design transmitting 150-250 kHz high frequency
• 600W power output with maximum depth capability of 106 m (350 ft)
• Wide 30° beamwidth for maximum bottom coverage
• Integrated fast-response water temperature sensor
• Low-profile bronze thru-hull housing suitable for stepped, planing, or displacement hulls
• Fixed 20° tilt element for 16-24° hull deadrise angles
• 70 mm (2-13/16") hole size required for installation
• Exclusive Xducer ID® technology for automatic transducer recognition
• Excellent shallow-water performance and target separation

Important: This transducer requires a Mix and Match cable specific to your fishfinder/chartplotter model for proper connection and operation.
