Furuno TM185HW High Wide CHIRP Transducer w/Temp Transom Mount

The Furuno TM185HW High Wide CHIRP Transducer with Temperature Transom Mount delivers the imaging clarity and depth coverage serious anglers demand when targeting structure, baitfish, and bottom composition. Built for both freshwater lakes and saltwater applications, this transom-mounted unit integrates seamlessly with Furuno fishfinder systems, giving you the sonar backbone needed to locate fish in variable water conditions. Whether you're running shallow flats or probing deeper offshore structure, the wide-beam CHIRP frequency spread captures detail across a broader cone angle than conventional single-frequency transducers.

CHIRP (Compressed High Intensity Radar Pulse) technology separates target details by transmitting a continuous range of frequencies rather than a single tone, resulting in superior target separation and reduced noise interference in real-world water columns. The integrated temperature sensor provides live water-column diagnostics—essential for understanding thermocline depth and seasonal fish movement patterns. The high-wide beam pattern balances coverage width with range capability, allowing you to scan broader areas while maintaining sufficient resolution to identify hard bottom, sand, and weed structure. Transom mounting keeps the unit flush against the hull, minimizing drag and turbulence compared to through-hull installations.

This transducer suits recreational anglers, tournament competitors, and professional guides who rely on fast, accurate bottom mapping and fish detection. It pairs directly with Furuno NavNet TZtouch2, GP1870F, and compatible multifunction displays, making integration straightforward on new builds or retrofit upgrades. Installation is non-invasive—no hull drilling required—making it ideal for fiberglass and aluminum hulls alike. For boaters running at speeds up to 60 mph, the transom-mount design maintains consistent signal quality across the entire speed range.
