Description
Airmar TM275C-LHW 1kW CHIRP Transducer | Boat Supply Store
Engineered for serious anglers, this 1kW CHIRP-ready transducer overcomes the limitations of single-frequency sonar by providing a continuous sweep of frequencies. Its high-frequency band (150-250 kHz) delivers exceptional target separation and resolution down to 500 feet with a constant 25° beamwidth, ideal for precisely identifying baitfish and structure. The low-frequency band (42-65 kHz) extends coverage to 3000 feet with a 25-16° beamwidth, ensuring comprehensive deep-water performance critical for offshore pursuits or navigating channels like those found in the Florida Keys.
Key Features

Common Concerns Answered
What is the additional cost and complexity of installation?
The Airmar TM275C-LHW requires a separate 'Mix and Match' cable, which increases the overall expense and installation process. Careful consideration of this separate component is necessary before purchase.
Is the transom mount durable against grounding incidents?
While designed for transom mounting, some users report that the mount can be vulnerable to damage if the vessel grounds or is beached. Proper placement and awareness of water depth are crucial to mitigate this risk.
How does the high-frequency beamwidth perform in extremely shallow water?
The wide beamwidth of the high-frequency band, while beneficial for coverage, may sometimes be too broad for extremely shallow water applications where precise targeting of individual fish is paramount. A narrower beam may be preferred in such specific scenarios.
