Airmar DT800 NMEA 2000 Thru-Hull Tilted Element Smart Sensor - 20°

The Airmar DT800 NMEA 2000 Thru-Hull Tilted Element Smart Sensor in 20° delivers real-time depth and water temperature data directly to your marine electronics network. Built for serious anglers and boaters who demand accurate sonar readings in variable bottom conditions, this transducer combines a tilted 20° element with advanced smart sensor technology to cut through interference and deliver consistent performance from coastal waters to freshwater lakes. The fixed 20° tilt angle compensates for hull deadrise, ensuring optimal signal transmission regardless of your vessel's design.

Operating at 235 kHz with 100 watts RMS power output and a tight 12° sonar cone, the DT800 delivers pinpoint target resolution—critical when you're marking structure, baitfish, and bottom composition in deeper water or high-traffic areas. The plastic thru-hull construction resists corrosion and survives saltwater environments without sacrificing acoustic clarity. Its NMEA 2000 connectivity integrates seamlessly with Garmin, Lowrance, Simrad, and compatible chartplotters, feeding depth and temperature data directly into your navigation and fish-finding workflow without additional interfaces or converters.

Boaters with moderate to high deadrise hulls—particularly center consoles, bay boats, and offshore sportfishers—benefit most from the tilted element design, which maintains beam angle consistency across typical planing attitudes. Installation requires a thru-hull opening (typically 2.25 inches), professional-grade sealant, and access to your vessel's keel or transom; most installations take 1–2 hours with basic marine tools. Compatible with all NMEA 2000-certified networks, this transducer pairs perfectly with modern digital displays and backup analog gauges, giving you redundancy and confidence when fishing remote waters or targeting deep-water species.
