Airmar B164 Bronze Thru-Hull Transducer 1kW 20°

Overview

Built for tournament and serious recreational anglers running center-console and trailered boats in the 25' to 35' range who need maximum sonar power without sacrificing speed or trailer handling. If you're running a fast boat and can't fit a high-performance fairing, this is your transducer.

The B164 delivers 1kW of power with a tilted-element ceramic array that keeps your beam vertical and concentrated directly below your boat — no fairing needed, no protrusion beyond 6.35mm, no performance hit. You get the power of a large transducer in a flush-mount package that won't hang up on trailer rollers or slow you down. This is Airmar's answer for anglers who refuse to compromise on sonar quality because of hull design or boat type.

Key Features

• 1kW Power Output — full 1 kilowatt of acoustic energy across dual 50kHz and 200kHz frequencies — gives you the range and definition serious structure fishing demands, especially in deep water or challenging bottom conditions.
• Tilted Element Technology — ceramic arrays are angled inside the housing to produce a perfectly vertical beam with maximum energy concentrated directly below — you see what's under you with clarity, not wasted side echoes.
• Flush-Mount Bronze Housing — protrudes less than 0.25 inches below your hull, so it sits flat on trailer bunks and rollers with zero risk of damage — your boat performs like it did before the transducer went in.
• 50/200kHz Dual Frequency — switches between 50kHz for deep structure and long-range detection, and 200kHz for shallow water and target separation — covers every depth scenario without swapping transducers.
• Integrated Water Temperature Sensor — tracks surface temperature in real time with fast response — one less through-hull hole to drill, one less thing to fail.
