Detailed FAQ Section

How do I install the Airmar B75C-20-HW on my boat?

Installing the Airmar B75C-20-HW requires careful selection of the hull location and proper sealing techniques. Begin by choosing a location free from turbulence and air bubbles, typically forward of the propeller. Drill the necessary hole at the correct angle for the 20° tilt. Apply marine sealant around the fitting, insert the transducer, and tighten the locking nut securely. Finally, connect the Mix-n-Match plug to your compatible sonar device. Always refer to the manufacturer’s installation guide for torque specifications and orientation details. A professional installer is recommended for optimal performance, especially if you’re unfamiliar with thru-hull installations.

What makes High Wide CHIRP better than standard CHIRP?

High Wide CHIRP technology offers a constant 25° beam width, which provides a much wider coverage area than standard narrow-beam CHIRP. This means you can scan more water, detect more fish, and get better resolution across the entire frequency range. The Airmar B75C-20-HW is particularly effective in shallow to mid-depth waters, where the wider beam excels at detecting fish near structures and in schools. Additionally, the frequency range of 150–250 kHz provides crisp target separation and greater detail on fish arches, making it ideal for serious anglers who rely on precise sonar imaging.

Is the Airmar B75C-20-HW compatible with my fishfinder?

Yes, the Airmar B75C-20-HW features a Mix-n-Match connector that allows it to integrate with a variety of fishfinder brands such as Garmin, Raymarine, Simrad, and Furuno. The plug-and-play design makes installation straightforward, and adapter cables are available for systems that require specific connectors. Always verify compatibility with your fishfinder’s specifications before purchase. If unsure, consult with your dealer or reach out to Airmar support for guidance on the correct adapter cable.

How do I maintain my Airmar B75C-20-HW transducer?

To maintain optimal performance, regularly inspect the transducer for marine growth, corrosion, or physical damage. Clean the face with a soft cloth and mild detergent, avoiding abrasive materials. Apply antifouling paint designed for transducers if marine growth is an issue in your region. Periodically check the wiring and Mix-n-Match plug for secure connections and signs of wear. Performing these maintenance tasks will ensure accurate sonar readings and extend the lifespan of your transducer.

What is the lifespan of the Airmar B75C-20-HW?

With proper care and maintenance, the Airmar B75C-20-HW can last over a decade. Its bronze housing is designed for long-term use in harsh saltwater environments, and the internal components are built to withstand continuous operation.
