Airmar B150M Transducer CHIRP Medium Frequency 0°

Overview

Who This Is For: Freshwater and inland anglers targeting bass, walleye, and panfish in shallow to medium depths. Built for fiberglass and wood hull boats where you need clear, high-resolution sonar without overspending on a full dual-frequency system.

Product Summary: The B150M is a medium-frequency CHIRP transducer that covers 95–155 kHz in a single housing. It delivers fast water temperature reads and depth soundings up to 2,500 feet, with a narrow to medium beamwidth (26° to 17°) that expands your viewing area and produces larger, clearer fish targets on your echo sounder. For anglers who fish inland waters and want reliable sonar performance at a straightforward price point, this is a solid choice.

Key Features

• Medium-Frequency CHIRP (95–155 kHz) — sweeps across a 60 kHz bandwidth to paint a wider, clearer picture of structure and fish — you'll see suspended targets and bottom composition with exceptional clarity in shallow and medium depths.
• 26° to 17° Beamwidth — cone narrows as frequency increases, expanding your coverage area and producing larger, more defined fish arcs — critical for distinguishing actual fish from clutter on screen.
• Ultra-Clear Target Resolution — the sweet spot frequency range is optimized for inland and freshwater use — fish and structure stand out without the noise you'd get from dual-frequency trade-offs.
• Depth and Fast-Response Temperature — reads bottom in real-time and updates water temperature quickly so you can adjust your approach on the fly.
• Bronze B619 Housing — thru-hull construction rated for 0–7° deadrise, meaning it fits most recreational fiberglass and wood hull boats with minimal fuss.

Specs & What's Included

Compatibility: This transducer is an 8-pin thru-hull model compatible with Garmin XS Series echo sounders. It requires a 300W power source from your chartplotter or fish finder. If you're not certain your unit supports 8-pin connectivity or 300W output, call or text us at (833) 831-4077 — we'll confirm fit before you buy.

What's Included: Transducer only. You will need a compatible Garmin XS Series echo sounder and appropriate thru-hull mounting hardware (not included) for installation.
