Product Details
Tilted Element™ DT800 NMEA2000 Bronze Flush Thru-hull Mount Transducer (DT820BV-235-N2) by Airmar®. Measures: Depth/Temperature. Frequency: 235kHz. Max Power: 100W. Accommodates Deadrise: 16° - 22°. Tilt: 20°. The DT800 utilizes Airmar’s proven Tilted Element ™ and broadband technologies in this depth and temperature Smart ™ Sensor. The DT800 is a low-profile, retractable, thru-hull sensor that accurately computes depth and temperature data and sends it to any NMEA 0183 or NMEA 2000 ® network. Airmar's Smart ™ Sensors have embedded microelectronics—the transducer element and signal processor are only millimeters apart. The signal from the depth transducer is processed right inside the sensor itself. All that is needed to receive depth and temperature data is a single cable into a compatible network or display.

Features
- Depth and fast-response water-temperature sensing
- Depth performance from 0.5 to 183 m (1.6 to 600')
- 235 kHz frequency prevents mutual interference with other echosounders on the vessel
- Retractable insert for cleaning and safe storage
The ceramic is tilted inside the housing, compensating for hull deadrise and orienting the transducer beam straight down. This results in strong echo returns and accurate depth readings. These low-profile housings do not affect hull performance and will give accurate readings at high speeds. The housing features a water valve which minimizes water entering the boat when the retractable insert is being removed and replaced with the blanking plug.
Airmar® is the primary supplier of ultrasonic transducers to manufacturers of marine electronics for recreational boating, sportfishing, and commercial fishing applications.
