Navico DT800 Plastic Depth Temp N2K 0°

Upgrade your marine electronics setup with a reliable depth and temperature sensor designed for seamless integration into modern boating systems. This untilted, plastic through-hull model delivers precise underwater readings, helping skippers navigate shallow waters and monitor environmental changes effortlessly.

Precision Engineered for Marine Adventures

Crafted with boaters in mind, this sensor mounts flush through the hull using a durable 51mm flanged plastic housing. Its zero-degree element points straight downward, capturing accurate depth measurements from 0.6 meters up to 600 meters, alongside real-time water temperature data. Whether you're trolling for fish, exploring coastal areas, or charting unfamiliar waters, these insights enhance safety and performance on every outing.

Effortless NMEA 2000 Connectivity

Plug-and-play simplicity defines this unit, thanks to its pre-wired 2-meter Micro-C cable. It communicates via standard NMEA 2000 protocols, sharing data across compatible displays, multifunction units, and autopilots without the hassle of speed inputs or complex wiring. This backbone-ready design minimizes installation time, letting you focus on the water rather than troubleshooting connections.

Standout Advantages Over Traditional Sensors

• Robust Plastic Construction: Resists corrosion in saltwater environments, ensuring longevity without the weight of metal alternatives.
• Untilted Design: Ideal for flat or near-vertical hull surfaces, providing undistorted beam patterns for clearer bottom contours.
• Compact Profile: Low-drag housing reduces turbulence, maintaining your vessel's hydrodynamic efficiency.
• Versatile Data Output: Supports PGNs for depth, temperature, and transducer status, feeding into popular marine networks.

Real-World Applications for Boaters

Anglers rely on its sensitivity to detect structure and bait schools, while cruisers appreciate temperature shifts signaling thermoclines or current edges. Sailors in racing scenarios use depth alerts to avoid groundings, and kayakers or small craft operators benefit from its straightforward setup on fiberglass hulls. Pair it with chartplotters for overlaid bathymetry, turning raw data into actionable intelligence.

Installation Insights for Optimal Performance

Choose a hull location forward of the propeller and away from strakes or thru-hulls that could interfere with the acoustic beam. Drill precisely for the 51mm housing, seal with marine-grade sealant, and connect to your NMEA 2000 T-connector. Fairing blocks aren't needed due to the untilted element, simplifying retrofits on trailered boats. Test in shallow water post-install to verify readings align with known depths.

Compatibility and Network Integration

This sensor thrives in ecosystems from leading marine brands, interfacing smoothly with displays that support NMEA 2000 depth/temp PGNs like 128267 and 130306. It's a drop-in upgrade for systems lacking dedicated transducers, expanding network coverage without custom adapters.

Long-Term Reliability Tips

Flush the sensor seasonally with fresh water to prevent marine growth. Inspect the cable for chafe during haul-outs, and store spares for offshore trips. Its IPX8-rated waterproofing handles submersion, but avoid antifouling paints on the face to preserve acoustic clarity.
