Airmar TM165HW Chirp High Wide 600W Transom Mount Transducer - Requires Adapter Cable

The Airmar TM165HW Chirp High Wide 600W Transom Mount Transducer is a cost-effective upgrade path for anglers and boaters ready to modernize their fish-finding capability without replacing their entire sonar system. Whether you're upgrading from an older single-frequency transducer or stepping up to dual-frequency CHIRP technology, this transom-mounted unit delivers the scanning performance serious fishermen expect. The 600-watt power output punches through structure, vegetation, and thermoclines to reveal what's holding fish beneath your hull.

Built on Airmar's proven transducer engineering, the TM165HW employs CHIRP technology to transmit a continuous sweep of frequencies rather than fixed single-frequency pulses, delivering superior target separation and clarity. The High Wide beam pattern covers more water column laterally, making it ideal for mapping structure from shallow bays to deeper offshore zones. Its compact transom-mount design fits most fiberglass and aluminum hull applications, and the 2.55 lb assembly installs cleanly below the waterline for minimal drag. Note that this model requires an appropriate adapter cable (sold separately) to integrate with your existing sonar head unit—verify your fishfinder's compatibility before purchase.

This transducer is best suited for boat owners upgrading legacy systems to modern CHIRP performance without the cost of a complete sonar replacement. Freshwater anglers pursuing bass, pike, and walleye in lakes with varied bottom composition will immediately notice improved target definition and clutter rejection compared to older technology. Coastal and Great Lakes boaters running 16- to 30-foot center consoles or open boats benefit from the wide beam's coverage and the unit's reliable saltwater-rated construction. Ensure your sonar unit supports CHIRP frequencies and check mounting options for your specific hull design before ordering.
