Unlock Reliable Depth and Temperature Readings on the Water

Imagine gliding through coastal waters or navigating tricky inlets without second-guessing your depth readings. The Raymarine DT800 12-degree tilt smart transducer delivers pinpoint accuracy for depth and water temperature, tailored for real-world boating challenges. Its clever design compensates for hull deadrise, ensuring the beam hits the seabed straight on, even on vessels with steeper angles. Boaters rave about how this integration transforms their Raymarine setups, feeding clean data directly into multifunction displays for safer passages and smarter fishing decisions.

What sets this transducer apart? It's not just about raw specs—it's engineered for seamless network connectivity via SeaTalkng, letting you calibrate everything from your helm station. Whether you're upgrading an older sounder or building a cutting-edge multifunction system, this unit slots in effortlessly, minimizing wiring hassles and maximizing performance.

Key Advantages for Everyday Boaters and Anglers

Dive deeper into why savvy mariners choose this transducer for their setups:

• Optimized Beam Angle: The built-in 12-degree tilt automatically adjusts for common hull shapes (10-20 degrees deadrise), delivering clearer bottom contours and fewer false echoes compared to flat-mounted alternatives.
• Interference-Free Operation: Running at 235 kHz, it sidesteps clashes with lower-frequency fishfinders or sonar systems, keeping your displays clutter-free during multi-device use.
• Impressive Range and Power: With 100 watts of output, it reliably tracks from shallow 0.5 meters (perfect for beaching or docking) up to 180 meters in deeper offshore zones—ideal for everything from bay cruising to bluewater adventures.
• Rugged Build for Harsh Marine Life: Housed in durable 2-inch high-strength plastic, it withstands fiberglass or aluminum hulls, backed by a retractable design with an integrated valve for quick, dry maintenance sessions.
• Plug-and-Play Simplicity: A generous 6-meter cable with SeaTalkng connector means fewer junctions and faster installs, compatible with Axiom chartplotters, i70s instruments, and the broader Raymarine ecosystem.

Real users highlight its edge in choppy conditions: the tilted element cuts through turbulence better, providing stable temp data for lure selection or engine cooling checks.

Effortless Installation and Calibration Tips

Setting up the DT800 feels more like an upgrade than a chore. Drill a clean 2-inch hole through-hull, secure the housing, and connect to your SeaTalkng backbone—no special tools needed beyond basics. For best results, position it forward of props and keels, at least one-third the waterline length from the bow. Calibration? Fire up your connected display, run a quick seabed test in calm water, and tweak offsets for spot-on accuracy. Pro tip: Pair it with an Axiom for automatic temp compensation, enhancing readings across varying salinities.

Maintenance shines here too—the retractable stem lets you lift it out of the water without hauling the boat, and the valve prevents drips. Rinse with fresh water after salty outings, and it'll serve seasons without a hitch.

Performance That Boosts Confidence On and Below the Surface

From pinpointing drop-offs for trophy fish to avoiding shallows on sunset cruises, this transducer empowers better decisions. Its depth precision aids in anchoring securely, while integrated temperature sensing reveals thermoclines where bait schools hide. Anglers love how the 235 kHz frequency excels at marking smaller targets without the muddled returns of broader beams. In Raymarine networks, data flows to radar overlays or AIS for a holistic picture—think collision avoidance fused with bottom tracking.

Compared to generic thru-hulls, the smart calibration via network displays eliminates guesswork, adapting to your boat's unique setup over time.
