Discover the power of advanced sonar technology tailored for serious anglers who demand clarity and coverage on every outing. The Raymarine TM185MW stands out with its CHIRP-ready design, delivering exceptional mid-depth performance that separates fish targets like never before. Whether you’re chasing pelagic species in the upper water column or scanning deeper structures, this transom-mount transducer ensures you see more fish in more detail, all from the back of your boat.
What sets it apart? Its medium-frequency range (60-100 kHz) combined with an ultra-wide beam—spanning 57° to 73° port-to-starboard and averaging 16° fore-aft—creates maximum coverage right under your vessel. This isn’t just about spotting fish; it’s about giving you the edge in spotting them first, even at speeds up to 30 knots.
Why Anglers Trust the TM185MW for Superior Fishfinding
Unmatched Target Separation: CHIRP technology sweeps across 40 kHz of bandwidth, painting crisp images of individual fish amid bait schools or wreck debris—far superior to fixed-frequency transducers.
Deep-Water Capability: Track depths up to 400 meters (1,300 feet) with 1 kW power, ideal for offshore adventures without compromising on resolution.
Fast-Response Temperature Sensing: Stay informed on water conditions that drive fish behavior, helping you adjust trolling speeds or lure choices on the fly.
Boat Speed Versatility: Performs reliably below 30 knots, making it a go-to for trailered fishing boats, center consoles, and day cruisers.
Xducer ID Technology: Simplifies setup by automatically identifying the transducer to compatible Raymarine sounders, reducing installation headaches.
Effortless Transom Installation for Trailered Boats
Designed for vessels where thru-hull mounts aren’t feasible, the TM185MW bolts securely to transoms angled between 2° and 22°. Position it 1/3 aft from the stern, ensuring the bracket clears the hull’s deadrise. Urethane housing and stainless steel bracket resist corrosion in saltwater, while the 9-meter cable reaches most console locations.
Pro tip: Dead reckoning your mount height above the waterline prevents air entrainment at speed. Anglers often pair it with Raymarine’s Element or Axiom series multifunction displays for plug-and-play CHIRP scanning.
Maintenance Made Simple
Wipe the face clean after each trip to avoid marine growth. The low-profile design minimizes drag and snag risks, and urethane lens withstands impacts better than plastic alternatives.
Real-World Performance: From Inshore to Offshore
In medium frequencies, this transducer excels at revealing bottom hardness variations—crucial for jigging over reefs or drifting live bait. The wide beam catches schooling fish that narrower cones miss, boosting hook-up rates during dawn patrols. Users report cleaner arches on gamefish like mahi-mahi or tuna, even in choppy seas.
For trailered boats, its rugged build survives launch ramps and highway hauls, outperforming bulkier in-hull options in shallow drafts.
Seamless Integration with Your Electronics
CHIRP-ready for single-band operation, it pairs effortlessly with Raymarine sounders supporting 1 kW transducers. Compatible across all hull types, from fiberglass to aluminum— no hull voids required.
