Garmin Airmar Smart Sensor Depth & temperature 20 Degree Tilted NMEA 2000 DT800

Enhance your boating experience with precise underwater insights that keep you safe and informed on every voyage. This thru-hull transducer stands out by seamlessly delivering real-time depth and water temperature readings straight to your NMEA 2000 network, eliminating the clutter of extra wiring or displays. Designed for hulls with a 16 to 24-degree deadrise, its 20-degree tilt ensures optimal beam angle without compromising performance, making it a go-to choice for serious anglers, cruisers, and navigators who demand reliability in choppy waters or calm bays alike.

Why Boaters Rely on This Smart Transducer

Imagine gliding through shallow drafts or tracking fish in deeper waters with confidence. At the heart of this sensor is a powerful 100-watt element operating at 235 kHz, capable of penetrating up to 600 feet. The narrow 12-degree beamwidth sharpens focus on the bottom structure, helping you spot drop-offs, wrecks, or schools of fish with exceptional clarity. Paired with temperature sensing, it gives you the full picture—vital data for adjusting trolling speeds, selecting lures, or simply avoiding hazards during low-visibility conditions.

What sets it apart? It's "smart" connectivity means plug-and-play integration with compatible chartplotters and multifunction displays. No more guesswork; your network receives calibrated data automatically, ready for overlays on your screens. With a sturdy 20-foot cable, installation reaches stern-mounted networks effortlessly, and the durable plastic housing withstands constant submersion without corrosion.

Seamless Installation for Lasting Performance

Getting this transducer up and running doesn't require a marine yard overhaul. Select a spot forward of the propeller and away from strakes for the cleanest readings—typically 1/3 of the hull length from the bow. Drill precisely, bed it in sealant, and secure with the included hardware. Pro tip: In colder climates, warm the hull surface first to prevent cracking, and always fair the mount to match your deadrise angle perfectly. Once connected to your NMEA 2000 backbone, it auto-configures, often within seconds. Follow best practices like routing cables away from engines to dodge interference, and you'll enjoy years of trouble-free operation.

• Prep Step: Clean and sand the hull interior for a watertight seal.
• Angle Check: Verify 20-degree tilt aligns with your hull's contour.
• Network Tie-In: Use T-connectors for easy drop-in to existing backbones.
• Test Run: Calibrate in known depths post-install to fine-tune accuracy.

Real-World Performance Across Conditions

Boat owners rave about its consistency—from coastal inlets where sudden shoals lurk, to offshore runs needing temp breaks for baitfish. The high-frequency design excels in shallower zones under 200 feet, minimizing clutter from suspended particles or thermoclines. In saltwater environments, its rugged build shrugs off barnacle buildup, while freshwater users appreciate the sensitivity for structure scanning. Whether you're chasing stripers in estuaries or cruising lakes, this sensor adapts, providing data that informs every decision on the water.

Maintenance That Keeps It Running Strong

Longevity starts with simple habits. After each trip, inspect the face for marine growth— a soft brush and eco-friendly cleaner restore it quickly. Annually, haul out and check the O-ring seal; replace if worn. Avoid high-pressure washes that could damage the ceramic element. Storing your vessel on blocks? Protect the thru-hull with a winter plug to prevent freezing. These steps ensure pinpoint accuracy season after season, maximizing your investment in marine electronics.
