Airmar TM275C-LHW 1kW Chirp Transom Mount Transducer

Airmar TM275C-LHW 1kW Chirp Transom Mount Transducer delivers wide-beam, high-resolution Chirp performance for superior fish targets and expansive coverage under your boat. Built for both inshore and pelagic fishing, this dual-frequency Chirp-ready transducer blends deep-water power with sharp shallow-water detail for a truly versatile sonar solution.

Key benefits

• Dual-frequency Chirp-ready: High Frequency 150–250 kHz with a constant 25° beam for excellent shallow-water detail and consistent coverage.
• Powerful low-frequency performance: Low Frequency 42–65 kHz with up to 1 kW of power, enabling deep readings to 914 m (3000') and flexible beamwidth from 25° down to 16°.
• Wide beam = more coverage: The high wide beam provides twice the coverage under the boat and clearer fish arches on the display compared to many high-frequency transducers.
• Deep-water capability plus 500' shallow water insight: Great deep-water performance with the depth- and fast-response water-temperature sensor for accurate readings in any condition.
• Transom-mount design: Robust stainless steel mounting bracket for easy installation on boats up to 10 m (32') with compatible hulls (fiberglass, wood, aluminum, or steel).
• Advanced technology: Exclusive Xducer ID® technology, eight internal broadband ceramic assemblies, and urethane housing ensure reliability and compatibility across a wide range of boats and sounder systems.
• Broad bandwidth coverage: 123 kHz of total bandwidth from a single transducer, covering popular 50 and 200 kHz frequencies plus everything in between.
• Installation notes: Requires appropriate Mix and Match Cable; transom angle range from 3° to 21°; weight ≈ 4 kg (8.9 lb).
