What does the Furuno DST-800MSF transducer measure?

It measures depth, speed through water via paddlewheel, and water temperature, all in one compact thru-hull unit.

Is the DST-800MSF suitable for sailboats?

Yes, its wide fan-shaped beam performs well on heeling sailboats and hulls with up to 22° deadrise.

How accurate is the speed reading at low speeds?

Patented processing ensures excellent accuracy below 5 knots (6 MPH), with smooth output at higher speeds.

What network does it connect to?

It's fully compatible with NMEA 2000 networks, with a LEN of 4 for easy integration.

Can I install this myself?

Absolutely—requires a single 51mm hull hole, marine sealant, and basic wiring to your NMEA backbone.

What's the temperature sensor accuracy?

Fast-response sensor provides ±0.2°C (±0.1°F) accuracy for reliable water temperature readings.

How deep can it detect?

Minimum sounding depth of 0.5m (1.6') up to a maximum of 70m (230').

Why choose thelockerguy wholesale?

Upgrade your vessel's navigation with the Furuno DST-800MSF thru-hull transducer, a versatile all-in-one solution that delivers precise depth, speed, and temperature data. Designed for seamless integration into bronze housings compatible with Airmar B617V styles, this smart sensor simplifies your setup by requiring just a single 51mm (2-inch) hull penetration. Whether you're retrofitting an existing boat or outfitting a new build, its compact design minimizes installation hassle while maximizing performance on the water.

Boat enthusiasts and professionals alike appreciate how this transducer handles challenging conditions. Its patented signal processing ensures reliable speed readings even below 5 knots, providing smooth, linear outputs across all speeds. The wide, fan-shaped beam excels on steep deadrise hulls or when your sailboat heels, ensuring consistent bottom detection. Pair that with a fast-response temperature sensor accurate to ±0.2°C (±0.1°F), and you have trustworthy data for safer, more efficient voyages.

Why Choose the DST-800MSF for Your Boat?

Triple Functionality: Combines depth, speed via paddlewheel, and temperature sensing in one robust unit, reducing wiring clutter and potential failure points.
NMEA 2000 Compatibility: Plug-and-play connectivity with a low Load Equivalency Number (LEN) of 4, making it ideal for expanding marine networks without overloading power supplies.
Versatile Mounting: Handles hull deadrise up to 22°, perfect for planing hulls, sailboats, or multihulls where traditional transducers might falter.
Durability in Harsh Environments: Urethane acoustic window and bronze housing withstand corrosion, impacts, and pressure down to 3m (10 feet), built for long-term marine use.
Real-Time Precision: Updates data every second with a pulse rate of 20,000 pulses per nautical mile, offering sonar-like depth from 0.5m (1.6 feet) to 70m (230 feet).

In practical terms, this means fewer false readings during trolling, accurate groundspeed for precise anchoring, and temperature insights for fishing hot spots or engine cooling monitoring. Mariners report enhanced confidence in shallow waters or during coastal cruising, where every bit of data counts.

Effortless Installation and Maintenance Tips

Installing the DST-800MSF is straightforward for DIYers or yards. Drill a precise 51mm hole, bed the bronze housing with marine sealant, and route the 6m standard cable to your NMEA 2000 backbone. Fairing blocks can optimize beam angle on steeper deadrises, boosting accuracy. Pro tip: Align the paddlewheel with the boat's water flow direction for peak speed performance—test at various speeds post-install to calibrate.

For maintenance, inspect the paddlewheel seasonally for marine growth; a quick freshwater rinse and spin-check keeps it spinning freely. The urethane window resists fouling better than plastic alternatives, but ultrasonic antifouling nearby can extend clean intervals. Operating on 11.5-25 VDC with just 40mA draw, it's efficient even on battery-powered setups.

Ideal Applications for Everyday Boaters

Fishermen love the DST-800MSF for its low-speed accuracy during drift fishing or jigging. Cruisers benefit from reliable depth in uncharted areas, while racers get speed data unaffected by heel. It's a staple on trailerable boats too—easy to install seasonally without permanent modifications. Compared to separate sensors, it cuts costs and complexity, delivering pro-grade data affordably.
