AIRMAR® DT800 (20° Tilt)
-
“I upgraded to the Garmin GT56UHD and the clarity is unbelievable. You can literally see fish moving around structure. Hard Rig Marine helped me pick the right setup and it’s been spot on since day one.”
Michael R. — Cairns, QLD -
“I’m not a tech person, but the team made it super easy to install my GT54UHD transducer. Works perfectly with my ECHOMAP — I’ve never had sonar this clear in the estuary before!”
Jenny L. — Mandurah, WA -
“The Airmar B175M changed my whole deep drop setup. Way better definition and stability compared to my old transducer. You get what you pay for — and these guys know their stuff.”
Ben T. — Newcastle, NSW
AIRMAR® DT800 (20° Tilt): NMEA 2000® Smart Thru-Hull Sensor
The AIRMAR® DT800 (20° tilt) is a specialized, **plastic smart thru-hull transducer** designed to enhance your vessel’s NMEA 2000 instrumentation network. It provides accurate **depth and water temperature** data directly to compatible Garmin displays and Chartplotters. Operating at 235 kHz, this 100 W sensor offers stable readings down to **600 feet (183 meters)**. The **20° tilt element** is internally corrected to ensure the sonar beam fires vertically on hulls with deadrise between **16 and 24 degrees**.
DEDICATED NMEA 2000 INSTRUMENTATION
The DT800 is a smart sensor, sending digital data directly onto the NMEA 2000 network, eliminating the need for complex wiring or black boxes.
KEY INSTRUMENTATION & INSTALLATION FEATURES
- NMEA 2000® Output: Provides depth and temperature data directly via the NMEA 2000 network, allowing instant viewing on any connected display.
- 20° Tilt Compensation: The integrated tilt corrects for deadrise between **16° and 24°**, crucial for deep-V hulls.
- 100 W Power: Supplies stable power for instrumentation functionality, reaching depths up to **600 feet**.
- Flush Mount: Plastic thru-hull housing ensures minimal drag and is safe for trailered boats.
CONNECTIVITY AND INTEGRATION
The DT800 is designed for simple, direct integration into your NMEA 2000 backbone.
- **Direct NMEA 2000:** Plug-and-play connection eliminates the need for separate sonar or power cables.
- **Frequency:** Operates at 235 kHz, providing reliable depth tracking, though it is not intended for detailed fishfinding.
Inverell Boating Centre Expert Note:
The AIRMAR DT800 (20° Tilt) is a dedicated **NMEA 2000 Smart Sensor** and does not provide traditional or scanning sonar imagery for fishfinding purposes. It is strictly a depth and temperature source. The 20° tilt is crucial for high-deadrise hulls (16°–24°). This unit is the easiest way to add digital depth and temp data to your network.
