The Airmar B117 is a 50/200 kHz dual-frequency transducer built around a single ceramic element housed in a low-profile bronze through-hull. With just 5 mm (3/16") projecting beyond the hull surface, it keeps drag to a minimum while delivering reliable depth and temperature data. Designed for center-console and trailered vessels 8 m (25') and larger, it pairs directly with Raymarine CP370 and DSM300 units via its factory-installed Ray connector.
