Airmar B175MW Transducer Medium Ultra Wide CHIRP 1kW 20°

Overview

Who This Is For: If you run a center console, express, or sportfish boat and want one transducer that handles the full mid-water column with exceptional clarity, this is your setup. Built for anglers targeting pelagic species, suspended structure, and fish in transition zones where you need real-time target separation and wide coverage at cruising speed.

Product Summary: The B175MW is a 1 kW thru-hull transducer that combines medium frequency (60-100 kHz) with an ultra-wide beamwidth to put you on fish fast and keep you on them. The 20° tilted element corrects for hull deadrise automatically, meaning you get maximum echo return and crisp sonar images whether you're at idle or on plane. This is the workhorse transducer when you need mid-depth performance and a broad picture of what's underneath.

Key Features

• 60-100 kHz Medium Frequency — splits the difference between deep-water penetration and high-resolution detail — you get excellent fish-target separation in the 30-200 foot range where most pelagic action happens.
• 57-73° Port-Starboard Beamwidth — ultra-wide coverage lets you see structure and baitfish to either side of your boat — critical for covering water fast without dead zones.
• 20° Fixed Tilted Element — ceramic element is angled to match typical hull deadrise (16-24°) so sonar cone points straight down no matter how your hull is built — no guesswork, no misaligned transducers giving you false readings.
• 1 kW Power with 400m Depth Rating — enough juice to reach structure and suspended targets at depth while maintaining clarity at speed; tracks targets accurately down to 1,300 feet.
• Dual Frequency Within Single Transducer — 40 kHz total bandwidth (60-100 kHz range) lets your sonar unit work with CHIRP technology for precision imaging and fast water-column interrogation without installing multiple transducers.
• Low-Profile Bronze Housing — thru-hull design minimizes drag and turbulence at planing speeds; bronze construction resists corrosion in salt and brackish water without sacrificing signal strength.
• Fast-Response Water Temperature Sensor — real-time temp readout helps you track thermoclines and seasonal baitfish movements without a separate probe.

Specs & What's Included

Compatibility: 12-pin Garmin connector only — works with current CHIRP-ready Garmin chartplotters and fish finders. If you run Humminbird, Lowrance, or Simrad, this transducer is not compatible. Not sure if this works with your setup? Call or text us at (833) 831-4077 — we'll tell you straight.
