Description
Airmar DT800 NMEA 2000 Transducer | Boat Supply Store
For boaters requiring accurate depth and temperature readings, this integrated NMEA 2000 sensor offers a streamlined solution without a fairing block. Its 20-degree fixed tilt element optimizes readings for hulls with 16-24 degree deadrise, and the 235 kHz frequency minimizes interference with other onboard systems. With a depth range of 1.6 to 594 feet and 100 Watts RMS power output, this low-profile, retractable unit ensures reliable data for coastal cruising or offshore fishing operations.

Common Concerns Answered
Will this transducer provide detailed underwater imaging like DownVü or SideVü?
The Airmar DT800 is designed for precise depth and temperature readings utilizing traditional sonar frequencies, not for advanced imaging like DownVü or SideVü. For detailed underwater imaging, consider transducers specifically engineered for those functions.
Is the installation of a thru-hull transducer difficult?
Installing a thru-hull transducer requires drilling a hole through the hull and ensuring a watertight seal, which can be complex for individuals unfamiliar with marine thru-hull fittings. Professional installation is recommended if you are not confident in your ability to perform this task correctly.
Can I use this transducer with any sonar unit?
The Airmar DT800 utilizes a 235 kHz frequency and outputs data via NMEA 2000. Ensure your sonar head unit is compatible with this specific frequency and NMEA 2000 data protocol for optimal performance.
