Airmar B75C-20-H 20d Tilt With Navico 7-Pin MM Cable

The Airmar B75C-20-H 20d Tilt With Navico 7-Pin MM Cable is a premium through-hull transducer built for serious anglers and boaters who demand reliable sonar performance in saltwater and freshwater environments. This transducer delivers the precision fish-finding capability that modern navigation systems require, pairing a proven Airmar hull design with Navico's trusted connectivity standard. Whether you're targeting structure on a coastal flat or mapping a deepwater channel, this transducer combines durability with the beam angle and frequency response needed to read bottom conditions and locate gamefish with confidence.

The B75C features a 20-degree cone angle that balances wide coverage with focused target detail—ideal for trolling, drifting, and stationary presentations across variable depths. The 7-pin Navico MM connector ensures plug-and-play integration with compatible Lowrance, Simrad, and B&G plotters and fishfinders, eliminating compatibility guesswork and simplifying installation. Built with a tilt-mount design, this transducer accommodates hull angles and mounting configurations common to center consoles, bay boats, and offshore rigs. The robust 5-pound bronze casting resists corrosion and absorbs vibration, extending service life even in high-speed conditions and rough seas.

This transducer is best suited for boaters running Navico-based electronics systems and those upgrading or replacing existing through-hull transducers on mid-to-large vessels. Installation requires a through-hull mounting hole; consult your boat's specifications and the transducer manual to confirm compatibility with your hull material and console layout. The tilt functionality allows fine-tuning of beam angle relative to hull deadrise, which is critical for maintaining consistent sonar performance as speed and sea state change. If you operate a dedicated fishing platform or cruising boat equipped with Lowrance or Simrad gear, the Airmar B75C-20-H delivers the reliability and performance that experienced anglers trust when fish location matters.
