Airmar DT800 Transducer Thru-Hull 20° Tilt NMEA 2000

Overview

Built for serious anglers running NMEA 2000 networks who need reliable depth and temperature data without fairing-block bulk. If your boat has moderate to steep deadrise (16°–24°) and you want a low-profile transducer that won't slow you down at plane, this is your answer.

The DT800 is a thru-hull transducer that does one job exceptionally well: delivers accurate depth and temperature across your network with a tilted ceramic element that compensates for hull deadrise. No fairing block means no drag penalty, no extra hole to drill, and cleaner hull lines. At 235 kHz with 12° cone angle, you get solid bottom tracking and temperature data from a single compact unit that retracts for service without taking on water.

Key Features

• Tilted Element Design (20° fixed tilt) — ceramic element angles inside the housing to match typical hull deadrise — eliminates the need for a fairing block while maintaining accurate readings at speed and across your entire depth range.
• 235 kHz Broadband Ceramic Technology — high-frequency element improves bottom resolution without sacrificing sensitivity — you'll see harder bottom returns and cleaner target separation in weeds or structure.
• Smart Sensor with Embedded Microelectronics — transducer element and signal processor sit millimeters apart — faster signal path means lower latency and more reliable data transmission over your NMEA 2000 network.
• Low-Profile Retractable Housing — minimizes water intrusion when you pull the transducer for seasonal service or maintenance — self-closing valve keeps your bilge dry.
• 12° Cone Angle — tight beam gives you precision depth readings and reduces false echoes from turbulence — critical when you're running hard or fishing in shallow, complex bottom.
• 100 Watts RMS Power — solid acoustic output for reliable bottom tracking even in deeper water or with structure-heavy bottoms.
• NMEA 2000 Native — integrates seamlessly into your existing 5-pin network — one cable, full data sharing across all compatible chartplotters and sonar units on your boat.

Specs & What's Included

Compatibility: The DT800 connects directly to any NMEA 2000 backbone via 5-pin connector. Works with fiberglass or metal hulls with 16°–24° deadrise; the 20° tilt angle is the sweet spot for most center console and offshore boats in that range. Depth range is 1.6–594 feet. Installation requires a 2-inch hole. Not sure if this matches your hull deadrise or your sonar head? Call or text us at (833) 831-4077 — we'll confirm compatibility straight.

In the Box: DT800 transducer with 20-foot cable and 5-pin NMEA 2000 connector. Mounting hardware sold separately; verify your through-hull fitting before ordering.
