Airmar TM275C-LHW Transducer With Navico MMC.

Airmar TM275C‑LHW Transom Mount Low/High Wide CHIRP Transducer Series

The Airmar TM275C‑LHW delivers best‑in‑class broadband CHIRP performance in a rugged transom‑mount housing. Designed for high‑clarity depth readings and ultra‑sensitive fish detection, it combines low‑frequency deep‑water capability with wide‑beam high‑frequency coverage to maximize performance for offshore and coastal anglers. Providing up to 123 kHz of total bandwidth, it covers the most popular fishing frequencies (50 kHz and 200 kHz included) so no fish or structure goes undetected beneath your boat.

The constant 25‑degree high‑frequency beam keeps targets crisp across the water column, while dual‑element operation with fast‑response temperature sensing ensures both precision and durability. Whether paired via Navico 7‑pin or 9‑pin Mix‑N‑Match cabling, the TM275C‑LHW is built to perform flawlessly with CHIRP‑ready echosounders.
