Furuno Smart Sensor f/FI50 TM DST

Upgrade your boating experience with the Furuno DST-800PWF, a versatile transom-mount smart sensor that delivers precise depth, speed, and temperature data right to your NMEA2000 network. Designed for boaters who demand reliability on the water—whether you're chasing fish offshore, racing on a sailboat, or cruising coastal waters—this compact unit punches above its weight with an 11-degree beam optimized for challenging hull angles up to 22 degrees deadrise.

Precision Performance Tailored for Real-World Boating

Crafted with Airmar's proven P39 housing style in durable molded plastic (P66 sealing), the DST-800PWF stands up to harsh marine environments while keeping installation straightforward. Its patent-pending speed signal processing ensures rock-solid readings from idle speeds up to 60 MPH, eliminating the guesswork caused by choppy conditions or hull slap. The 235 kHz frequency penetrates to 500 feet, providing clear bottom tracking even on planing hulls or when heeled over during tacks.

What sets this sensor apart? Temperature accuracy within ±1°F means you'll know exactly when baitfish are holding in that thermocline, giving you an edge during tournament fishing or when navigating tricky shallows. The wide fore-aft fan-shaped beam adapts to high-speed operations and steep deadrises, making it a go-to for center consoles, sportfishers, and performance sailboats alike.

Seamless Integration with Your Electronics

As a plug-and-play NMEA2000 device, it connects effortlessly to Furuno's FI50 wind displays or any compatible multifunction display (MFD). No complex wiring—just route the 19.6-foot cable (6 meters) from the transom to your network backbone. The 5-pin connector snaps in securely, and with a 100-watt power rating, it draws minimal juice from your system.

• Depth Capability: Reliable returns to 500 feet for offshore adventures.
• Speed Range: Stable data from 1-60 MPH, perfect for both trawlers and go-fast boats.
• Beam Width: 11 degrees for consistent bottom lock on angled hulls.
• Hull Compatibility: Handles up to 22-degree deadrise without performance loss.

Effortless Installation and Long-Term Reliability

Installing the DST-800PWF is a weekend warrior's dream: Drill a single 2-inch hole in your transom, bed it in marine sealant, and torque to spec. Position it 1/3 from the transom's edge, parallel to the waterline, for optimal speed logs. Pro tip: On stepped hulls, angle it slightly downward to avoid aeration at speed. Once mounted, calibrate via your MFD for personalized speed-through-water accuracy, factoring in your vessel's unique displacement.

Backed by a robust build, it shrugs off fouling with its streamlined shape, and regular fresh-water rinses keep it humming season after season. Boaters report years of trouble-free service, even in brackish bays or after grounding scares.

Ideal Applications Across Boating Styles

For offshore anglers, it pinpoints wrecks and ledges with confidence. Sailors appreciate the heel-resistant beam during races. Powerboaters love the no-drill speed calibration that rivals more expensive thru-hulls. If you're retrofitting an older NMEA2000 setup or building a new tournament rig, this sensor delivers pro-level data without the premium price tag.

Maintenance Tips for Peak Performance

Keep your DST-800PWF thriving with simple habits: After every saltwater outing, flush with fresh water to prevent salt buildup. Inspect the cable strain relief annually, and gently clean the face with a soft brush and boat soap—no abrasives. In winter storage, remove if possible or protect the thru-hull with antifreeze. These steps ensure continued accuracy and extend its lifespan far beyond the standard warranty.
