Airmar TM275C-Transducer With Garmin 12-Pin MMC.

Airmar TM275C‑LHW & TM265C‑LH Transom Mount CHIRP Transducer Series

The Airmar TM275C‑LHW and TM265C‑LH transducers deliver advanced broadband CHIRP performance for precise fish targeting, structure detail, and deep‑water coverage. Designed for small to mid‑size sport‑fishing and offshore vessels, both models combine exceptional low‑frequency penetration with sharp high‑frequency resolution. Featuring robust urethane housings, stainless steel mounts, and Airmar’s proven Mix‑N‑Match 12‑pin Garmin connection, these transducers pair seamlessly with CHIRP‑ready echosounders for superior clarity and range.
