Airmar B175 Medium Ultra-Wide Transducer 1kW 12° 12-Pin

Overview

Built for serious anglers targeting pelagic and mid-water species — stripers, mackerel, tuna, and suspended gamefish in depths beyond 200 feet. If you fish deeper water and need maximum horizontal coverage under your boat without sacrificing mid-depth detail, this is your transducer.

The B175 Medium Ultra-Wide is a 1 kW thru-hull transducer that delivers exceptional beamwidth (57–73° side-to-side) paired with medium frequency (60–100 kHz) for superior target separation and depth performance down to 1,300 feet. The tilted ceramic element automatically corrects for your hull's deadrise, so you get vertical imaging the moment you drop it in — no guesswork, no dead zones. It's the kind of tool that reveals the difference between a sparse bite and a loaded bite.

Key Features

• Ultra-Wide Beamwidth (57–73° port/starboard, 16° fore/aft) — covers nearly three-quarters of the area directly beneath your boat — you'll spot fish and structure across the full width of your sweep, especially critical for mobile anglers and those running over open water.
• Medium Frequency (60–100 kHz) with 40 kHz Bandwidth — sits between low and high frequency for excellent mid-depth performance and crisp fish-target separation — you see individual baitfish and gamefish distinctly, not as a smear on screen.
• 1 kW Power, 1,300-Foot Depth Rating — delivers strong echo return and depth tracking in deep water and structure-rich environments — critical for pelagic and deep-ledge work where weak signals mean missed fish.
• Tilted Element Housing (20°, 12°, or 0° angle options) — ceramic element auto-corrects for hull deadrise and installs nearly flush to the hull — you get vertical beam orientation without manual adjustment, and low-profile design preserves speed and fuel efficiency.
• Bronze Housing — built for stepped, planing, or displacement hulls — no compatibility surprises; it works on your boat regardless of hull shape.
• Fast-Response Temperature Sensor — tracks water temperature in real time as you move — essential for finding the temperature breaks and seasonal patterns that trigger bites.
• CHIRP-Ready Design — compatible with CHIRP sonar networks when paired with a compatible Garmin chartplotter — opens the door to frequency-stacking and advanced sonar imaging as your electronics grow.
• Xducer ID Technology — automatic transducer recognition on compatible systems — saves setup time and eliminates manual configuration errors.
