Airmar B175L 20° CHIRP Bronze Thru-Hull 1kW - Needs Mix & Match Cable

The Airmar B175L 20° CHIRP Bronze Thru-Hull 1kW - Needs Mix & Match Cable is a professional-grade solution for serious offshore anglers seeking superior target separation in the deepest parts of the water column. Designed for vessels with deadrise angles between 16 and 24 degrees, this tilted element transducer allows for a flush-mount installation that minimizes drag while keeping the beam pointed straight at the seabed. By operating on a low frequency range, it provides the necessary penetration to find structure and pelagic species that standard transducers often miss. This 1kW powerhouse is an essential component for any high-performance marine electronics suite designed for blue-water expeditions.

This transducer utilizes a wide-band frequency range of 40 to 60 kHz, allowing it to deliver exceptionally clear imaging and precise depth readings even at high speeds. The bronze housing provides a durable, corrosion-resistant interface with the hull, ensuring long-term reliability in harsh saltwater environments. With 1,000 watts of power, the unit effectively cuts through noise and surface clutter to reveal bait balls and trophy fish at depths where traditional sonar loses clarity. Internal ceramic arrays are permanently tilted at a 20-degree offset to compensate for the hull's deadrise, eliminating the need for bulky external fairing blocks.

Captains and tournament anglers benefit most from the B175L’s ability to track the bottom at extreme depths while simultaneously providing accurate sea surface temperature data. Because this model requires a specific Airmar Mix & Match cable, it offers the flexibility to integrate with various sonar brands by simply selecting the appropriate adapter for your specific display. The flush-mount design is ideal for trailerable boats or stepped hulls where a protruding transducer would cause turbulence or risk damage during transport. Investing in this high-performance transducer ensures your vessel is equipped with the industry standard for deep-water fish finding and bathymetric mapping.
