Airmar SS175L Transducer CHIRP 12° Thru Hull

Overview

Built for anglers running boats up to 36 feet who need precise bottom detection and fish marking without breaking the bank on multiple transducers. Charter captains, tournament anglers, and serious recreational fishermen trust broadband CHIRP technology to separate baitfish from game fish and structure in ways single-frequency transducers can't match.

The SS175L is a low-frequency CHIRP transducer that handles the grunt work of finding fish and structure with exceptional clarity. One installation delivers 35 kHz of total bandwidth — covering the popular 50 kHz sweet spot plus the entire 40–60 kHz range. The tilted 12° element and urethane acoustic window are engineered for steel and aluminum hulls with 8–15° deadrise, keeping your install simple and your sonar sharp.

Key Features

• CHIRP Broadband 40–60 kHz — sweeps across a full bandwidth range instead of a single frequency, giving you 5 to 10 times greater detail and resolution so you can distinguish individual baitfish, game fish, and bottom composition at a glance.
• 35 kHz Total Bandwidth — delivers consistent 50 kHz performance (the most popular fishing frequency) plus flexibility across the entire low-frequency range from one transducer installation.
• Bottom Detection to 10,000 Feet — cuts through the water column fast with high-definition returns, critical when you're marking suspended structure or deep-water schools.
• 12° Tilted Element with 21–32° Beamwidth — the tilt optimizes forward-looking capability and reduces dead zones directly under your boat, so you see structure coming before you're directly over it.
• Integrated Temperature Sensor — real-time water-temperature feedback without a separate install, helping you pattern seasonal fish movement and adjust tactics on the fly.
• Stainless Steel Housing — built to handle saltwater spray and freshwater corrosion, so this transducer works hard for years without degradation.
• Fast Response — CHIRP processing delivers near-instantaneous bottom updates and target returns, critical when you're moving at speed or scanning structure.

Specs & What's Included

Compatibility: Designed for steel or aluminum hulls with 8–15° deadrise on boats up to 36 feet. Thru-hull installation with urethane acoustic window.
