Airmar B164 Transducer 1kW 20° Tilted Element

Overview

Who This Is For: Serious anglers running center-console or trailered boats up to 36 feet who need 1 kW sonar power without sacrificing the ability to load on a trailer. If you're running moderate deadrise (16–24°), fish deep water, and want maximum sensitivity without a fairing that hangs below your hull, this transducer is built for you.

Product Summary: The B164 is a flush-mount, dual-frequency transducer that delivers full 1 kW power in a housing that extends less than a quarter-inch below your hull. The tilted ceramic element inside is angled to match your boat's deadrise, sending a clean vertical beam straight down—no matter your angle. You get 50 kHz for deep structure and 200 kHz for detail, all in one compact bronze housing that won't catch on trailer bunks or slow you down.

Key Features

• 1 kW Power Output — full power without requiring a high-performance fairing — you get the sensitivity of a big transducer in a small package that clears your trailer completely.
• Tilted Element Design — ceramic arrays angled inside the housing to compensate for your boat's deadrise — delivers a clean vertical beam at any angle, not a tilted one that wastes energy off to the sides.
• Dual-Frequency (50/200 kHz) — 50 kHz with 22° beamwidth reaches 1,800 feet for open water; 200 kHz with 6° beamwidth gives you tight detail on structure down to 800 feet — switch between them based on depth and bottom type.
• Ultra-Low Profile Housing — extends only 6.35 mm (0.25 inch) below the hull, so it sits safely on trailer rollers and bunks without modification — no hauling damage, no performance hit underway.
• Temperature Sensing — built-in sensor gives you real-time water temp at the transducer face — critical for seasonal bite windows and thermocline location.
• Fixed 20° Tilt — engineered for 16–24° deadrise angles common in center-console and fishing boats — if your hull falls in that range, this is optimized for you.
