Airmar TM260 Transducer 1kW Transom Mount

Overview

Built for serious bottom fishermen and deep-water trollers running boats 25' to 40' with Simrad or Lowrance systems. If you're chasing ground fish, working wrecks, or need reliable sonar in extreme depths, this is your transducer.

The TM260 is a professional-grade transom-mount transducer that delivers the imaging clarity of Airmar's legendary B260 without the complexity of in-hull installation. Dual-frequency broadband sonar (50 kHz and 200 kHz) separates baitfish from gamefish, locks onto tight-holding bottom structure, and performs clean at speeds up to 30 knots. For anglers who demand deep-water penetration and precision beam control, this transducer pays for itself in confidence on every trip.

Key Features

• Dual-frequency broadband sonar — 50 kHz and 200 kHz in one element — switches between wide coverage and narrow precision without sacrificing image quality on the water.
• Wide 19° beam at 50 kHz — covers more bottom structure and suspended fish in deeper water, letting you work larger areas efficiently.
• Narrow 6° beam at 200 kHz — cuts through clutter and shows you the difference between a clean bottom and a boulder or wreck holding fish.
• Up to 2,500' depth capability at 50 kHz — takes you into extreme offshore and lake depths where standard transducers go blank.
• 1 kW power output — delivers strong signal return in rough water, debris-filled bottoms, and challenging conditions where weak transducers fail.
• Kick-up assembly — locks in the up position and won't damage your transom if you hit shallow water or structure; no wrestling with a stuck transducer.
• Streamlined urethane housing — hydrodynamic design holds clean sonar data at speed without turbulence noise or signal dropout above 25 knots.
• Transom mount installation — no drilling through the hull; mount and run in under an hour with the included rugged bracket.
• Temperature sensing — water temperature overlay helps you identify thermoclines and seasonal fish movement patterns.
