Airmar B75C-20-H-8G CHIRP Transducer 20° High Frequency 8-Pin for Garmin

The Airmar B75C-20-H-8G is a high-performance bronze through-hull CHIRP transducer designed specifically for Garmin chartplotters and fishfinders. This transducer features a narrow 20-degree beam angle for high-frequency operation, providing exceptional bottom detail and target separation in deeper waters.

Advanced CHIRP Technology:

Airmar's Broadband CHIRP (Compressed High-Intensity Radial Pulse) technology represents the next generation of fishfinding capability. Unlike traditional single-frequency transducers, CHIRP transducers transmit a continuous sweep of frequencies, delivering superior target definition, enhanced fish arch identification, and better noise rejection. This allows anglers to distinguish individual fish in a school and identify game fish from baitfish with unprecedented clarity.

Key Features:

• 20-degree narrow beam angle optimized for high-frequency performance in deep water
• Bronze housing with fairing block for durable through-hull installation
• 8-pin connector compatible with Garmin marine electronics
• High-frequency CHIRP band for maximum detail and resolution
• Low-profile design minimizes drag and turbulence
• Depth and fast-response temperature sensor integrated
• Suitable for fiberglass and wood hulls with deadrise angles up to 20 degrees

Installation:

This through-hull transducer is designed for permanent installation below the waterline and includes a fairing block to match hull deadrise angles. The bronze construction provides excellent durability in saltwater environments while maintaining optimal acoustic performance. Professional installation is recommended to ensure proper alignment and sealing.

The B75C-20-H-8G is ideal for serious offshore anglers and cruisers who demand the highest level of underwater clarity and target definition from their marine electronics.
