Airmar DT820PV-235-N2 DT800 NMEA 2000 Thru-Hull Depth Temperature Transducer 20° Tilt

The Airmar DT800 is a low-profile, retractable thru-hull smart sensor that combines depth and temperature measurement in a single compact housing. Designed for power and sailboats with 16° to 24° hull deadrise, this transducer features a fixed 20° tilted element that compensates for hull angle without requiring an external fairing block.

Key Features:

• Tilted element design positions the ceramic element at the optimal angle inside the housing, eliminating the need for a hull-protruding fairing block
• Broadband Ceramic Technology at 235 kHz delivers improved resolution and sensitivity while preventing interference with other onboard echo sounders
• Smart Sensor technology with embedded microelectronics places the transducer element and signal processor millimeters apart for superior performance
• Retractable housing with self-closing valve allows transducer removal for servicing while minimizing water intrusion
• Low-profile design maintains hull performance and provides accurate readings even at high speeds
• 12° narrow beam angle with 100 watts RMS power for precise depth detection from 1.6 to 594 feet

Technical Specifications:

• Frequency: 235 kHz with 12° cone angle
• Fixed tilt angle: 20° (optimized for 16° - 24° hull deadrise)
• Housing material: Plastic with urethane acoustic window
• Connection: 5-pin NMEA 2000 with 20 ft. cable
• Installation hole diameter: 2 inches
• Dimensions: 4.92" H x 2.94" OD
• Compatible with fiberglass or metal hulls

This thru-hull transducer integrates seamlessly with NMEA 2000 networks, providing reliable depth and temperature data for navigation and fish-finding applications.
