Airmar B265LH Transducer CHIRP Thru Hull 12-Pin Garmin

Overview

Who This Is For: Built for serious inshore and offshore anglers running boats 25 feet and larger who need to identify and target specific fish species across a wide range of depths. If you're hunting everything from tuna and squid in deep water to cod in canyon systems, this transducer gives you the frequency control to match your target.

The B265LH CHIRP Thru Hull is a dual-frequency powerhouse that puts 103 kHz of total bandwidth under your boat in a single transducer. It covers the exact frequencies commercial fishermen use to separate game fish from bait, mark structure at all depths, and hold bottom detail even at speed. Pair it with a tunable Garmin fish finder and you get the logbook-style precision that turns water time into consistent catches.

Key Features

• Dual-Frequency CHIRP Broadband — transmits across 42–65 kHz low and 130–210 kHz high with 103 kHz of total bandwidth — lets you dial in the exact frequency that marks your target species with the sharpest image, whether you're on tuna (60 kHz), squid (133 kHz), or cod (175 kHz).
• Adaptive Beam Width — low frequency delivers a wide 25° beam that narrows to 16° as you tune up; high frequency offers 10° to 6° adjustability — wider beams cover more water column in shallow areas, narrow beams give pinpoint precision in deep structure.
• Fast-Response Water Temperature Sensor — feeds live temp data to your display — critical for locating thermoclines and seasonal depth zones where fish hold.
• High-Performance Fairing — included with the transducer — maintains clean broadband data at speeds over 30 knots, so your sonar doesn't turn to garbage when you're running hard between marks.
• Bronze Housing with Urethane Acoustic Window — built tough for saltwater operation and saltwater speeds — won't delaminate or fail from repeated cavitation cycles.
• Exclusive Xducer ID Technology — automatic transducer recognition — one less setup headache, especially if you're running networked systems across your boat.
