Discover the power of precise underwater detection with the Raymarine TM1150M transom-mount transducer, a game-changer for anglers and boaters chasing fish in shallow coastal waters or inland lakes. This CHIRP-enabled sensor combines depth tracking with fast-response temperature readings, delivering crystal-clear images of the bottom structure, baitfish schools, and trophy targets holding near wrecks or drop-offs. Whether you're trolling for walleye in freshwater shallows or hunting snapper along inshore reefs, its medium-frequency range punches through to reveal details others miss.

Why Choose the TM1150M for Your Next Fishing Adventure?

Unlike basic fixed-frequency transducers that blur fast-moving fish or cluttered bottoms, the TM1150M's CHIRP technology sweeps across 95-155 kHz, adapting to conditions for superior target separation. Narrowing from 26° to 17° beamwidth, it focuses energy where it counts—on separated arches for individual fish rather than vague clouds. Boaters rave about its reliability on planing hulls up to 8 meters, where it maintains solid bottom lock even at speed. The urethane housing and plastic release bracket shrug off impacts from debris, keeping you on the fish without downtime.

Key Features That Set It Apart

• CHIRP Excellence: 60 kHz bandwidth for unmatched resolution in 0-183m depths, perfect for inshore and coastal pursuits.
• Dual Sensing: Depth plus rapid temperature updates to track thermoclines and locate active bait zones.
• Smart Mounting: Transom design fits outboards and I/Os with 3°-20° deadrise; release mount protects on impact.
• Plug-and-Play Tech: Patented Xducer ID® auto-identifies to compatible Raymarine sounders, simplifying setup.
• Versatile Power: Handles 300W efficiently, scaling to 1kW systems for deeper punch when needed.

Real-World Performance on the Water

Picture this: You're running a 7m center console off the beach, scanning for flounder in 5-30m. The TM1150M paints sharp bottom contours, distinguishing soft mud from hard shell beds, while highlighting suspended schools amid grass lines. In choppy conditions, its focused beam cuts noise, and the temp sensor alerts you to upwellings drawing predators. Pair it with modern multifunction displays for A-Scope views that confirm hookups before the rod bends. Freshwater anglers targeting bass near docks love how it excels in skinny water without losing lock on 50m+ depths.

Effortless Installation Tips for Peak Performance

Mounting is straightforward—position 1/3 from transom center, parallel to waterline at rest. Use the included bracket for quick-release security; urethane stands up to saltwater abuse. Route the cable inside the hull to avoid snags, and angle slightly down for optimal cone coverage. Test at idle and plane-out to fine-tune—no drilling required for most setups. Pro tip: Dead rise over 20°? Consider the thru-hull B150M cousin for seamless integration.
