Product Detail
The Airmar B75C-12-L-HB is a top - notch depth and fast - response water - temperature sensor. It features low - CHIRP from 40 kHz to 75 kHz with a 32° to 21° beamwidth. With 300 W of power, it can reach a maximum depth of 353 m (1200'), offering great deep - water performance. Its low - profile, thru - hull housing gives good display resolution at speed when properly installed. Recommended for stepped, planing, or displacement hulls, it has a bronze housing for use in fiberglass or wood hulls. The low - frequency band (40 - 75 kHz) is a deep - water performer, providing excellent coverage and tracking. Just one installation of the B75L transducer delivers up to 35 kHz of total bandwidth. When installed almost flush to the hull, the element tilt corrects for hull deadrise, ensuring accurate depth readings. It offers a greater depth range, wider beamwidth, and more under - boat coverage. The Chirp signal processing technology used with AIRMAR broadband, Chirp - ready transducers provides more detail at greater depths and is less noisy. It's also great for high - speed boat operation. Cable length is 9 m (30'), deadrise range is 8 to 16°, and it's a CHIRP - Ready Single - Band transducer. The package includes B75C - 12 - L - MM and MMC - HB Cable.
Using this Airmar transducer is easy. First, make sure your boat has a suitable hull type like stepped, planing, or displacement, and is made of fiberglass or wood. When installing, place the transducer almost flush to the hull so the element tilt can correct for the hull deadrise and give you accurate depth readings. Once installed, it will start measuring the water depth and temperature. Remember, this transducer works best at high boat speeds and in deep water. For maintenance, regularly check the cable for any signs of wear or damage. Keep the transducer clean, especially if you've been in dirty or salty water. If you notice any issues with the depth or temperature readings, check the installation to ensure it's still secure. That's all you need to know to get the most out of your Airmar transducer.
