Airmar TM185C Medium & High Wide CHIRP Transom Mount Transducer Series for Si‑Tex 8‑Pin.

Airmar TM185C Medium & High Wide CHIRP Transom Mount Transducer Series for Si‑Tex 8‑Pin

The Airmar TM185C transducers combine advanced CHIRP technology with Airmar’s proven transom‑mount design for unmatched target resolution, bottom definition, and reliability. Available in Medium (85–135 kHz) and High Wide (150–250 kHz) frequencies, these 1 kW models deliver exceptional performance for inshore, offshore, and freshwater fishing applications.

Engineered for outboard and I/O‑powered boats, each transducer features a urethane housing, stainless steel mounting bracket, and built‑in fast‑response temperature sensor. Airmar’s Xducer ID® technology simplifies installation and ensures optimal CHIRP tuning on Si‑Tex CHIRP‑compatible sounders.
