Upgrade your boat's instrumentation with the Furuno DST-800PSF, a versatile thru-hull smart sensor that combines depth, speed, and water temperature readings into a single, low-profile unit. Designed for seamless integration, this retractable multisensor punches just one hole through your hull, saving time and effort during installation while delivering precise data to your NMEA2000 network.

Boat owners and builders appreciate its adaptability, especially on challenging hull designs like high-deadrise powerboats or sailboats. The innovative fan-shaped beam at 235 kHz ensures reliable bottom tracking, even when the boat heels or pitches, providing consistent performance across a variety of conditions.

Key Advantages for Everyday Boating

This sensor stands out by prioritizing accuracy and ease of use. Its advanced speed signal processing—powered by Airmar technology—delivers stable readings from as low as 1 mph up to 60 mph, helping you navigate safely without sudden fluctuations that could mislead your displays. Temperature sensing is equally reliable, with precision within ±1°C, perfect for monitoring water conditions during fishing trips or long cruises.

The near-flush P17 molded plastic housing protrudes only 5 mm (3/16 inch) beyond the hull, reducing drag and maintaining your boat's hydrodynamic efficiency. When it's time for service or winter storage, the removable insert and self-jacking cap make extraction straightforward—no need for dry-docking or special tools.

Effortless Integration and Reliability

As a plug-and-play NMEA2000 device, the DST-800PSF connects via its 6-meter cable with a 5-pin Micro-C connector, broadcasting data directly to compatible chartplotters, multifunction displays, and instruments like Furuno's FI50 series. This all-in-one solution declutters your network, eliminates the need for multiple transducers, and simplifies wiring for cleaner bilges.

Whether you're racing, trawling offshore, or day-sailing, this sensor enhances situational awareness with real-time metrics. Its rugged construction withstands harsh marine environments, ensuring years of dependable operation without frequent recalibrations.

Practical Tips for Optimal Performance

• Placement matters: Install forward of the propellers and away from strakes for the cleanest speed logs. On sailboats, position it amidships to handle heeling angles.
• Fan beam benefits: The wide fore-aft coverage excels in deeper waters up to practical limits, reducing false readings on uneven seabeds.
• Maintenance made simple: Rinse with fresh water after saltwater use, and leverage the retractable design for off-season care.
• Network synergy: Pair it with NMEA2000 hubs for multi-station data sharing across your vessel.

Invest in the DST-800PSF for a sensor that blends cutting-edge tech with user-focused design, giving you confidence on the water without the hassles of traditional setups.
