Airmar TM165HW Transducer CHIRP High Wide 600W Transom Mount

Overview

Built for anglers running boats up to 25 feet who want to upgrade an older single-frequency or non-CHIRP transducer without replacing their entire sonar unit. Whether you're fishing shallow structure or suspended fish, this transom mount delivers the detail and coverage you need at a fraction of the cost of a new system.

The TM165HW is a high-frequency CHIRP transducer that trades narrow, deep-focused beams for a wider coverage cone — meaning you see more of the water column around your boat, especially in the upper 50 feet where most fish live. You get crisp, noise-free images with stronger fish targets and better bottom definition. It's the kind of upgrade that immediately changes what you see on the screen.

Key Features

• Super Wide 30° Beam — covers 3x the area under your boat compared to standard high-frequency transducers — you detect suspended fish and structure you'd miss with a narrow beam.
• High Frequency 150–250 kHz — delivers superior shallow-water performance, crisp bottom detail, and excellent fish target separation — critical when you're picking apart brush piles or drop-offs.
• 600W Power with 500' Max Depth — enough power to cut through stained water and get solid returns in deeper structure, yet rated for boats and conditions you actually fish.
• Depth and Water Temperature Sensor — gives you real-time temp data without a separate sensor, helping you locate thermoclines and seasonal patterns.
• Low-Profile Transom Design — mounts cleanly on fiberglass, metal, or wood hulls without sacrificing performance at speed.
• Xducer ID Technology — automatic transducer recognition eliminates guesswork during installation and reduces setup errors.
