Description
Airmar DST800 Nylon Thru-Hull NMEA2000 | Boat Supply Store
Navigate complex waters with an integrated depth, speed, and temperature solution that performs reliably across challenging hull designs and heeling conditions. This Smart™ TRIDUCER® Multisensor operates at a 235 kHz frequency, preventing interference with other sonar systems, and provides precise depth readings from 1.6 to 600 feet. Its embedded microelectronics process signals within the low-profile, retractable thru-hull housing, requiring a single NMEA 2000 connection for seamless data integration, making it an essential component for serious offshore anglers.
Key Features
- Integrate depth, speed, and temperature into a single, compact unit.
- Prevent mutual interference with other echo sounders using its 235 kHz frequency.
- Achieve reliable bottom detection across a wide operating range from 500 mm to 185 m (1.6 to 600').
- Benefit from a wide, port-starboard, fan-shaped beam for consistent data acquisition.
- Obtain fast-response temperature readings with ±0.2°C (±0.1°F) accuracy.
- Choose from NMEA 2000 certified or NMEA 0183 connectivity options.
- Maintain a clean hull profile with a low-profile, retractable thru-hull fitting.
- Ensure durability and corrosion resistance with a robust nylon housing.

Common Concerns Answered
How do I ensure accurate speed calibration with the Airmar DST800 on my specific hull type?
While most hull types yield accurate speed data, some installations may require fine-tuning calibration within your MFD's settings. Consult your Airmar manual and MFD's advanced settings for specific calibration procedures to optimize accuracy for your vessel's performance characteristics.
What maintenance is required for the DST800's retractable mechanism to prevent stiffness?
Regularly deploying and retracting the sensor, especially after prolonged submersion or in brackish/saltwater environments, helps maintain the integrity of the retractable mechanism. A light application of marine-grade lubricant to the shaft seal may be beneficial if stiffness is noted over time.
Are there specific configuration steps needed when integrating the DST800 with non-Airmar displays?
Yes, while NMEA 2000 certification ensures broad compatibility, some multi-function displays (MFDs) may require manual selection of the transducer type or network configuration settings. Refer to both your MFD's user manual and the DST800 installation guide for detailed integration protocols.
