Airmar B175HW Bronze Thru Hull 0° Tilt - 1kW

The Airmar B175HW Bronze Thru Hull 0° Tilt - 1kW is a wide-beam CHIRP transducer built specifically for anglers who demand superior sonar coverage under their hull. This bronze through-hull transducer combines Airmar's broadband CHIRP technology with an expanded beam width, delivering twice the underwater visibility compared to conventional high-frequency transducers while maintaining the precision frequency range essential for modern fish-finding.

Operating across a 150–250 kHz frequency band, this 1kW transducer generates a constant 25° beam width—the key specification that sets it apart in the current Airmar lineup. The wider beam means less dead zones directly beneath your vessel and superior target detection in shallow to moderate depths. The 0° tilt angle positions the transducer for straight-down operation, ideal for boats where you need direct bottom and mid-water column imaging without angle compensation. Bronze construction provides corrosion resistance in saltwater environments, a critical factor for coastal and offshore anglers who operate in harsh marine conditions.

This unit is purpose-built for CHIRP-ready echo sounders and sounder units capable of supporting Airmar's broadband transducer technology. It suits both weekend recreational anglers working coastal waters and serious offshore tournament fishermen who rely on maximum sonar performance for competitive advantage. The through-hull mounting design is permanent and requires proper installation through the hull, making it a long-term commitment to superior fish detection rather than a portable solution.

The B175HW represents Airmar's commitment to wide-beam CHIRP technology in the marine sonar market. Its expanded 25° beam width fundamentally changes how anglers see underwater structure and baitfish movement, providing the coverage advantage that translates to more confident fishing decisions and improved catch rates on the water.
