Airmar B265C-LH-HB 1kW Low/High Frequency Broadband CHIRP Thru-Hull Transducer with High Speed Fairing for Humminbird 9-Pin

Low Frequency: 42 kHz - 65 kHz High Frequency 130 kHz - 210 kHz

Imagine knowing what exact frequencies work the best at detecting specific fish species: Bluefin Tuna—60 kHz, Squid—133 kHz, and Cod—175 kHz. Now imagine tuning your fishfinder to these frequencies, marking the fish precisely on the screen, then catching them! With the B265 transducer connected to a tunable fishfinder, you too can have a log book like a commercial fisherman. This powerhouse transducer delivers extreme target detail, bottom discrimination, and bait and game fish separation at all depths down to 914 m (3,000’). The Broadband B265 is the industry’s first, fully-tunable, 1 kW, thru-hull transducer. As tunable fishfinders become more common in the sportfishing market, captains will adjust the fishfinder and transducer frequency based on the fishing conditions and target species.

Fully Tunable

The B265 is packed with a seven-element, low-frequency array that operates at anywhere between 40 kHz and 60 kHz. It has a wide, 25° beam that will adjust by several degrees as the frequency is tuned up or down the band. The single, high-frequency ceramic operates at any frequency between 130 kHz and 210 kHz and has a narrow, 6° beam that is adjustable by several degrees. The included High-Performance Fairing will give you broadband performance at speeds over 30 knots (34 MPH). We will leave it up to you to discover the rest of the secrets that can be unlocked with tunable, Broadband Transducer Technology.
