Airmar B164 Transducer 1kW 0° Thru Hull

Overview

Built for tournament and sport-fishing anglers running fast, trailered boats where hull fairings aren't an option. If you're running hard between spots and need clean sonar data on a tight installation envelope, the B164 delivers without the complications of external housings or custom fairing work.

The B164 is a 1kW bronze thru-hull transducer engineered for speed and reliability. It pairs dual-frequency capability with a fast-response temperature sensor, giving you both broad coverage and precision depth on the same head. At 1000W of power, you'll get strong returns even in thick cover and rough conditions — and the low-profile design means no drag penalty on your hull.

Key Features

• 1000W Power Output — delivers strong sonar returns in dense cover, murky water, and rough conditions — you'll see fish and structure other anglers miss.
• Dual-Frequency (50kHz / 200kHz) — 50kHz gives you wide coverage and deep reach for structure and suspended fish; 200kHz gives you precise bottom definition and target separation in shallow water — switch between them on the water based on what you're fishing.
• Fast-Response Temperature Sensor — tracks thermocline shifts and water temperature changes in real time — critical for offshore fishing and seasonal pattern changes.
• Low-Profile Bronze Housing — installs flush with your hull on boats with 0-7 degree deadrise — no external fairing required, which means zero performance penalty and less maintenance.
• 0° Tilt Angle — engineered specifically for boats with minimal hull deadrise — you get optimal beam angle without compromise.
• 3.875" Installation Hole — fits standard thru-hull mounts on tournament and production boats — straightforward installation with no fabrication.
