Airmar B175MW Transducer Medium Ultra Wide CHIRP 20°

Overview

Built for serious anglers running 20 to 36-foot boats who need wide coverage of the mid-water column—especially when you're targeting pelagics, suspended fish, or anything in the 60 to 400-foot depth range. This transducer pairs perfectly with a Furuno TZTouch3 system and works best when you want medium-frequency performance without sacrificing the breadth of your sonar picture.

The B175MW is a tilted-element thru-hull transducer that delivers a 57 to 73-degree port-starboard beam—one of the widest medium-frequency patterns available. It runs at 1 kW with 40 kHz of total bandwidth, giving you the separation you need to pick individual fish out of a crowd while covering massive ground under your boat. The 20-degree tilt corrects for typical hull deadrise, so you get clean vertical returns even when you're running.

Key Features

• Ultra-wide 57–73° port-starboard beamwidth with 16° fore-aft coverage — you see everything under the boat and well to both sides, perfect for locating wide-spread structure and suspended gamefish without panning the transducer.
• Medium frequency 60–100 kHz — superior mid-depth performance and excellent fish-target separation, so you're not fooled by baitfish clouds or thermocline noise.
• 1 kW power with 40 kHz bandwidth from a single transducer — enough punch to reach 400 meters (1,300 feet) and enough frequency range to work everything from 60 up to 100 kHz without switching units.
• Tilted-element design with fixed 20° angle — corrects for hull deadrise automatically, meaning your sonar reads vertically even at cruise speed instead of firing backward or forward at an angle.
• Bronze thru-hull housing — proven durability on stepped, planing, and displacement hulls; flush installation minimizes drag and keeps resolution sharp when you're moving.
• Fast-response depth and water-temperature sensors — real-time feedback on bottom structure and thermal layers so you can fish the breaklines and layers where fish actually live.
• Xducer ID technology — automatic transducer identification with your TZTouch3, eliminating manual configuration hassles and ensuring you're always running the right frequency settings.

Specs & What's Included

Compatibility: Furuno TZTouch3 12-inch and 16-inch displays only. The 12-pin connector is specific to Furuno; this will not work with Lowrance, Simrad, Garmin, Humminbird, or other sonar systems.

What's Included: The B175MW transducer with 9-meter (30-foot) or 10-meter (33-foot) cable options. You'll need a TZTouch3 display and a compatible thru-hull installation (requires a 95 mm / 3.75-inch hole). The transducer is rated for boats up to 11 meters (36 feet) LOA.
