Raymarine TM185MW 1Kw Depth and Temperature CHIRP Transom Mount Product Description
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.
Frequently Asked Questions
What depth range does the Raymarine TM185MW transducer cover?
It tracks depths down to 400 meters (1,300 feet), making it suitable for both inshore and offshore fishing with excellent mid-depth resolution.
Is the TM185MW suitable for high-speed boating?
Yes, it delivers strong performance at boat speeds below 30 knots, ideal for planing hulls without significant signal loss.
How does CHIRP technology improve fishfinding compared to traditional sonar?
CHIRP provides wider bandwidth for better target separation, sharper images, and reduced noise, helping distinguish fish from structure or bait.
What transom angles work with this transducer?
It fits transoms from 2° to 22°, ensuring optimal beam projection for most small to mid-sized boats.
Does it include temperature sensing?
Absolutely—a fast-response thermistor delivers real-time water temperature data to help track thermoclines and fish preferences.
Can this transducer be used on aluminum hulls?
Yes, its urethane housing is compatible with all hull materials, including aluminum, fiberglass, and wood.
What's the beam width of the TM185MW?
Ultra-wide at 57° to 73° port-to-starboard and 16° average fore-aft, maximizing coverage under the boat.

AIRMAR’s innovative transducer designs have revolutionized the fishing world, and they continue to do so with the NEW Chirp-ready TM185 Medium Ultra-Wide (MW) Transom Mount transducer. The TM185MW takes transducer design and performance to a whole new level by using medium frequency (60-100 kHz) with an incredible ultra-wide beamwidth ranging from 57-73° port-starboard to 16° average fore-aft. Maximum coverage under the boat is achieved with this medium-frequency transducer, serving anglers who target pelagic species in the upper water column. Airmar’s new Medium Ultra-Wide models are perfect for seeking deeper species with a frequency band from 60?100 kHz.
The TM185MW Transom Mount is a 1 kW transducer housed in one of AIRMAR’s most popular housings. Transom models are best suited for small and trailered vessels where a thruhull installation is not practical. Simple to install and ideal for small trailered vessels where a thru-hull may interfere with loading.
