Airmar B164 Transducer 1 kW Bronze Thru-Hull 50/200 kHz

Overview

Built for center-console and trailered boats where hull space is tight and you need serious sonar power without a fairing. If you run a fast boat that sits on bunks, tow it regularly, or fish in depths beyond 200 feet, this is the transducer that gives you 1 kW performance in a low-profile package.

The B164 is a dual-frequency thru-hull transducer that delivers full 1 kW power from a bronze housing that barely protrudes below your hull—less than a quarter inch. You get 50 kHz for deep-water distance and 200 kHz for target separation and detail. It mounts flush, it won't slow you down, and it connects to any 600W or 1 kW echo sounder on the market.

Key Features

• Dual-frequency sonar (50/200 kHz) — covers shallow structure with precision and reaches deep water with wide coverage — you'll mark fish at any depth from 0 to 1,800 feet without changing transducers.
• 1 kW power without a fairing — full professional-grade punch in a compact design — your sounder will display crisp detail and fast response even in rough water.
• Low-profile bronze housing (less than 6.35 mm below hull) — sits on trailer rollers and bunks without interference — your boat runs at full speed and handles the same whether you're trailering or floating.
• Tilted Element design — ceramic arrays are angled internally to produce a perfectly vertical beam directly below your boat — maximum energy where you need it, regardless of your hull's deadrise angle.
• Fast water temperature sensing — gives you real-time thermocline data to dial in seasonal patterns — essential for targeting cold-water fish in summer or warm-water refuges in winter.
• Rated for hulls with 0° to 7° deadrise — engineered specifically for center-console and moderate-V hulls — confirms compatibility before you drill.
