Airmar DST800 Transducer Thru-Hull NMEA 2000

Overview

Built for serious anglers and cruising boaters who want depth, speed, and temperature data without cluttering their console with multiple cables and transducers. Whether you're running a high-deadrise center console, a heeling sailboat, or a conventional hull, this single compact unit pulls its weight.

The DST800 is a three-in-one thru-hull transducer that sends depth, water speed, and temperature directly to your NMEA 2000 network or compatible display. One cable. One housing. All the data you need to read the bottom, track your drift speed, and monitor water conditions — especially useful when you're chasing temperature-dependent species like stripers or trout in deeper water.

Key Features

• Three sensors in one housing — depth, speed, and temperature — eliminates the need for separate transducers and cables cluttering your install.
• Wide port-starboard fan-shaped beam — finds bottom reliably even on high-deadrise hulls or when your sailboat heels, so you get consistent readings in real conditions instead of guessing when the boat is listing.
• 235 kHz frequency — won't interfere with other echo sounders aboard, critical if you're running multiple sonar units or fishing around other boats running similar gear.
• Fast-response temperature sensor with ±0.2°C accuracy — gives you precise water temperature in near-real-time, essential for identifying thermoclines and predicting where fish will hold.
• Depth range from 1.6 to 600 feet — handles everything from skinny flats to offshore structure without losing signal.
• Embedded microelectronics — the transducer element and signal processor sit millimeters apart inside the housing, so all processing happens at the source and you get clean, noise-free data.

Specs & What's Included

Compatibility: Works with any NMEA 2000 network or NMEA 0183 display. Install it on any boat with a thru-hull opening — comes in plastic, bronze, or stainless steel housings to match your hull material and saltwater vs. freshwater environment. The unit includes a water valve for safe installation. Not sure if this works with your setup? Call or text us at (833) 831-4077 — we'll tell you straight.

In the Box: DST800 transducer housing, NMEA 2000 certified cable, and water valve. No display or additional sensors included.
