Raymarine TM185HW 1Kw Depth and Temperature CHIRP Transom Mount

Unlock Superior Shallow-Water Insights with the Raymarine TM185HW

Imagine gliding through coastal waters or chasing pelagics offshore, where every sonar ping reveals hidden structures, bait schools, and trophy fish with crystal clarity. The Raymarine TM185HW transom-mount transducer delivers exactly that, blending high-frequency CHIRP prowess with a generous wide beam for unmatched coverage. Anglers and boaters who demand precision in shallow zones—down to intricate bottom contours and separated targets—find this 1kW unit indispensable for elevating their on-water game.

Why the Wide-Beam Design Changes Everything

Unlike traditional narrow-beam transducers that leave gaps in your scan, the TM185HW's fixed 25° beamwidth sweeps twice the area in the upper water column. Operating across 150-250 kHz, it locks onto the sweet spot around 200 kHz for baitfish and gamefish while spanning 100 kHz of bandwidth. This means sharper fish arches, detailed wrecks, and drop-offs, even in depths up to 500 feet. Paired with fast-response temperature sensing, you'll track thermoclines and prime feeding zones effortlessly.

Real-World Advantages for Inshore and Offshore Pursuits

• Enhanced Fish Detection: Constant wide coverage spots schools from beam edges, reducing missed opportunities during drifts or trolls.
• Shallow-Water Mastery: Superior resolution picks out structure and targets where high frequencies shine, ideal for flats fishing or reef hopping.
• Rugged Build for Demanding Conditions: SEALCAST urethane housing shrugs off impacts, UV, and corrosion, backed by a stainless steel bracket for secure transom fit.
• Versatile Hull Compatibility: Thrives on planing hulls, displacement boats, outboards, or I/Os—up to 33 feet LOA.

Seamless Installation on Your Vessel

Mounting the TM185HW is straightforward for DIY enthusiasts or pros. Aim for a 3° to 21° transom angle to match your hull's deadrise, ensuring the ceramic face stays perpendicular to the waterline for optimal beam projection. Drill-free bracket secures firmly, and the 9.2 lb. unit positions low on the transom to minimize air entrainment at speed. Pro tip: Pair with anti-fouling paint on the housing for longevity in fouled waters, and route cables away from interference sources like engines for clean signals.

Patented Tech That Sets It Apart

Raymarine's Xducer ID technology auto-identifies the transducer on compatible multifunction displays, streamlining setup and preventing mix-ups. CHIRP-ready design future-proofs your system, adapting to evolving sounder tech without hardware swaps. For those eyeing alternatives, this model's transom focus outperforms in-hull or thru-hull options on smaller craft needing quick installs and easy service.

Long-Term Reliability in Harsh Marine Environments

Crafted with seamless urethane over precision ceramics, the TM185HW withstands pounding seas and trailering stresses. Regular freshwater rinses post-salt exposure keep the fast-temp probe accurate, while avoiding high-pressure washes preserves the acoustic window. Boaters report years of flawless performance, making it a smart investment for frequent fishers chasing stripers, snapper, or tuna.
