Airmar B150M Transducer CHIRP Medium Frequency 300W

Overview

Who This Is For: Freshwater and inland anglers fishing shallow to medium depths who want CHIRP sonar without overspending. If you're targeting bass, walleye, or panfish in lakes under 2,500 feet and fish in clear water where target separation matters, this is your transducer.

Product Summary: The B150M is a medium-frequency CHIRP transducer that gives you 60 kHz of total bandwidth in a single unit—that means you're sweeping from 95 to 155 kHz and covering the popular 107 kHz fishing frequency plus everything in between. On your sounder, you'll see larger, clearer fish targets and structure definition that makes the difference between marking a spot and actually understanding what's down there.

Key Features

• CHIRP Medium Frequency (95-155 kHz) — sweeps across a 60 kHz bandwidth to deliver precise target separation and expanded viewing area — you get larger, clearer images of fish and structure on your display with a single transducer instead of juggling dual frequencies.
• 26° to 17° Beamwidth — the medium-frequency sweep pattern expands your viewing cone as you fish shallower water — this means better coverage and fewer dead spots when you're working shallow flats or transition zones.
• Fast-Response Water Temperature — integrated temperature sensor delivers real-time readings — critical for understanding seasonal fish behavior and confirming thermocline location without running a separate probe.
• Bronze Housing (B619) — corrosion-resistant construction built for freshwater and inland use — ensures reliable performance season after season without premature degradation.
• Shallow to Medium Depth Range — rated for depths up to 2,500 feet — realistic performance in the 0-1,000-foot range where most recreational freshwater fishing happens, with strong signal quality in typical lake conditions.
