Garmin 95/155KHZ TM150M Transom Mount Depth/Temp

Upgrade your boating setup with a reliable transom mount transducer that delivers precise depth readings and water temperature data right where you need it. Designed for anglers and recreational boaters who demand clarity beneath the surface, this dual-frequency sensor scans wide areas in shallow waters and narrows in for detailed views at greater depths. Whether you're chasing fish in coastal bays or navigating unfamiliar waters, it provides the real-time intel to keep you safe and successful on the water.

Superior Dual-Frequency Performance

Operating at 95/155 kHz, this transducer balances coverage and resolution perfectly. The low-frequency 95 kHz beam spreads out to 26 degrees, ideal for spotting structure and baitfish schools across broader search areas in shallower zones. Switch to the high-frequency 155 kHz with its tighter 17-degree beam for pinpoint accuracy when depths increase, helping you zero in on bottom contours and wrecks up to 1,500 feet down. Paired with 300 watts of power, it punches through thermoclines and murky conditions better than many entry-level options, ensuring consistent performance from dawn patrols to late-night drifts.

Key Features That Matter on the Water

• Depth and Temperature Sensing: Tracks water column depth alongside surface temperature fluctuations, crucial for locating thermoclines where fish stage.
• Transom-Mount Design: Fits 3-20 degree transom angles seamlessly, minimizing drag and turbulence for cleaner hull runs.
• 8-Pin Connector: Secure, plug-and-play integration that stands up to saltwater exposure and vibrations.
• Plastic Housing: Lightweight and corrosion-resistant, perfect for fiberglass and aluminum hulls without adding unnecessary weight.

Effortless Installation for Weekend Warriors

Setting this up takes less time than rigging your rods. Clean your transom, mark the optimal height (about 1/8 inch above the hull bottom for best results), drill, and mount with included hardware. Adjust the running angle to match your boat's deadrise—typically 10-15 degrees works wonders for planing hulls—then route the cable inside away from strays and bilge pumps. Pro tip: Apply marine sealant around screw holes to thwart leaks, and test in shallow water to fine-tune the downward tilt, avoiding air bubbles that ghost your screen.

Real-World Reliability for Everyday Boaters

Boat owners rave about its sensitivity in spotting subtle bottom changes during low-light bites or when currents shift sandbars. Unlike bulkier thru-hull models, it thrives on trailered day boats and center consoles, delivering stable readings even at trolling speeds up to 30 knots. In choppy bays, the focused beams cut through noise, while temp data helps dial in lure choices—warmer shallows for bass, cooler depths for walleye. It's built to handle the rigors of brackish estuaries without fading, keeping your display sharp season after season.

Care Tips to Maximize Longevity

Rinse with fresh water after every saltwater trip to prevent salt buildup. Inspect the face for nicks or marine growth during off-season storage, and gently clean with a soft brush and non-abrasive soap. Avoid high-pressure washers that could damage the ceramic element. If trailering frequently, consider a protective kick-up bracket to guard against ramps.
