Raymarine TM185HW 1Kw Depth and Temperature CHIRP Transom Mount

The Raymarine TM185HW 1Kw Depth and Temperature CHIRP Transom Mount is a professional-grade transducer built for serious anglers and boaters who demand accurate, real-time bottom imaging and water-temperature data. Whether you're targeting structure in deep offshore waters or navigating shallow inland systems, this transom-mounted unit delivers the precision sounder performance that separates confident fishing from guesswork. The CHIRP technology and 1-kilowatt power output make this transducer equally at home on a tournament bass boat, saltwater center console, or dedicated offshore vessel.

Operating across a high-frequency band of 150 to 250 kHz, the TM185HW delivers depth readings down to 500 feet with a constant 25-degree beamwidth—wide enough to paint a clear picture of the bottom and any suspended targets, yet focused enough to eliminate false echoes in choppy conditions. The fast-response temperature sensor tracks water-temperature shifts in real time, critical information for identifying thermoclines and seasonal feeding zones where gamefish congregate. CHIRP pulse compression technology cuts through noise and clutter, giving you sharper target separation and cleaner sounder returns even at depth or in turbid water. The 1 kW power rating ensures maximum range and signal penetration without sacrificing clarity or battery drain.

This transducer is ideal for anglers running Raymarine sounder systems and looking to upgrade their depth and temperature capability without replacing the entire network. Transom mounting keeps installation straightforward on almost any hull type—fiberglass, aluminum, or composite—and the rugged stainless-steel housing withstands saltwater spray, impacts, and years of hard use. The TM185HW integrates seamlessly with Raymarine's full ecosystem of displays and network protocols, making it a plug-and-play addition to existing systems.
