Discover the Precision of the Furuno DST-810MSF Multisensor

Boat owners seeking reliable, all-in-one performance know that a quality thru-hull transducer can transform how you navigate challenging waters. The Furuno DST-810MSF stands out as a bronze thru-hull powerhouse, delivering digital depth, speed-through-water, water temperature, and even heel and trim data—all seamlessly integrated into your NMEA2000 network. Crafted with a durable bronze housing, this sensor thrives in saltwater environments, resisting corrosion while providing pinpoint accuracy for both powerboats and sailboats with deadrises up to 22 degrees.

What sets this multisensor apart? Its advanced 5 Hz speed updates deliver smoother, real-time readings from idle speeds below 5 knots up to 45 knots, helping you make confident decisions during fishing runs, races, or coastal cruises. The integrated attitude sensor corrects for heel and trim, ensuring data stays true even when your vessel lists or pitches. Pair it with the free CAST app via Bluetooth for effortless wireless calibration—no laptop required.

Key Features That Elevate Your Boating Experience

• Triple-Threat Sensing: Combines depth at 235 kHz (from 1.6 feet to over 300 feet), paddlewheel speed with patented signal processing, and fast-response temperature sensing (±0.2°C accuracy).
• Smart Attitude Integration: Built-in heel and trim sensors provide ±1° accuracy post-calibration, ideal for sailors optimizing sail trim or powerboaters tracking performance.
• Wireless Convenience: Bluetooth Low Energy connects to the CAST app for depth offsets, speed calibration at multiple heel angles, and firmware updates—up to 30 feet range.
• Robust Bronze Design: Urethane acoustic window in a corrosion-resistant housing withstands harsh marine conditions; pressure-rated to 10 feet.
• Plug-and-Play NMEA2000: 6-meter DeviceNet cable with 5-pin connector and low LEN (3) minimizes network load; powers from 9-25 VDC.

Benefits for Real-World Boating

Imagine threading through shallow reefs with confidence— the DST-810MSF's wide fan-shaped beam locks onto the bottom reliably, even on heeled sailboats. Anglers appreciate the stable speed data for precise trolling, while racers value the high-pulse-rate paddlewheel (20,000 pulses per nautical mile) for unmatched low-speed accuracy. Maintenance is a breeze: the modular insert design allows easy servicing without hauling the boat. Over time, this sensor pays for itself by reducing guesswork and enhancing safety on every outing.

For vessels with steep deadrises, the 11-degree beam and 22-degree compatibility ensure no blind spots. Temperature readings help monitor baitfish layers or engine cooling, adding layers of utility beyond basic navigation.

Effortless Installation Tips

Installing a thru-hull like the DST-810MSF requires care for optimal performance. Select a flat hull section forward of the prop, away from strakes or keels. Drill a 51mm (2-inch) hole, bed the bronze housing in sealant, and secure the insert. Route the NMEA2000 cable neatly, connecting directly to your network backbone. Use the CAST app to fine-tune: enter up to 10 speed points, set heel corrections, and verify attitude calibration. Most boaters complete this in under an hour, with no special tools beyond a hole saw.

"Switching to the DST-810MSF gave my sailboat the edge in tight races—heel-corrected speed data is a game-changer." – Experienced racer feedback.
