The Airmar DST800 is a Smart™ TRIDUCER® Multisensor that integrates depth, speed, and temperature sensing into a single compact thru-hull fitting. Embedded microelectronics position the transducer element and signal processor mere millimeters apart inside the housing, delivering fully processed data over a single cable to any compatible NMEA 0183 or NMEA 2000® display or network. The wide port-starboard fan-shaped beam maintains reliable bottom tracking on high-deadrise hulls and heeling sailboats alike.

Specifications:

• Measures depth, speed, and temperature in one compact thru-hull housing
• Operating frequency: 235 kHz — minimizes mutual interference with other echo sounders aboard
• Depth range: 500 mm to 185 m (1.6 to 600 ft)
• Wide port-starboard fan-shaped beam for reliable bottom tracking on high-deadrise hulls and heeling sailboats
• Fast-response temperature sensor accuracy: ±0.2°C (±0.1°F)
• Available as a Smart Sensor at 235 kHz or as an analog output sensor at 200 or 235 kHz
• Compatible with NMEA 0183 or NMEA 2000 networks
• Housing options: plastic, bronze, or stainless steel, each with a water valve
• Includes NMEA 2000 certified or NMEA 0183 cable depending on configuration selected
