Expert Overview

The Airmar B765C-LM Bronze CHIRP Transducer is a thru-hull solution designed for enhanced bottom detection in marine environments. This transducer is suitable for smaller boats, specifically those up to 9 meters (30 feet) and above, with compatibility for fiberglass or wood hull types. It supports hull deadrise up to 24 degrees when utilizing its high-performance fairing. Operating on low and medium CHIRP frequencies (40-75 kHz and 80-130 kHz respectively), it provides an 85 kHz total bandwidth from a single unit. This allows for detailed resolution down to 3,000 meters (10,000 feet), aiding in the differentiation of underwater structures and fish. The B765C-LM-MM includes a depth and fast-response water-temperature sensor and requires a mix and match cable for integration. It is not compatible with Simrad and Lowrance systems.
