Navigating challenging waters demands precision instruments that deliver reliable data without compromising your vessel's integrity. The Raymarine DST810 Gen2 stands out as a versatile thru-hull multisensor, combining depth, speed, and temperature readings into a single, low-profile unit. Boaters appreciate its retractable design, which minimizes drag while ensuring consistent performance across a wide range of hull types and conditions.

Seamless Integration for Smarter Boating

This sensor communicates effortlessly via a single NMEA2000 cable, simplifying wiring and reducing clutter in tight engine spaces. Pair it with Raymarine multifunction displays and instruments through the SeaTalkng connector, and you'll unlock a networked ecosystem where real-time data enhances every journey—from leisurely cruises to competitive racing. The built-in vessel attitude sensor tracks heel and trim, providing critical insights for optimized performance and safer handling in rough seas.

Precision Speed Measurement Redefined

The Gen2 paddlewheel innovation shines in speed accuracy, capturing data reliably from as low as 0.3 knots up to 45 knots. This broad range suits everything from slow trolling for trophy fish to high-speed passages. Forget inconsistent log readings; this transducer factors in water flow dynamics for speed-through-water metrics that GPS alone can't match, helping you fine-tune fuel efficiency and arrival times.

Bluetooth Calibration: User-Friendly Accuracy

Calibration has never been simpler. Connect via Bluetooth to the intuitive CAST app from Airmar, and perform speed-through-water adjustments right from your smartphone. No need for specialized tools or dry-docking—tweak settings underway, accounting for hull fouling or unique water conditions. This wireless feature empowers everyday skippers and seasoned pros alike to maintain peak accuracy season after season.

Built for Demanding Marine Environments

Crafted from durable plastic, the DST810 Gen2 thrives on fiberglass or aluminum hulls with deadrise angles up to 22 degrees. Its rugged construction withstands constant water exposure, impacts from debris, and temperature swings, backed by proven longevity in professional fleets. Retractability protects the sensor during haul-outs or beaching, extending service life without added maintenance hassles.

Effortless Installation and Maintenance

Installing a thru-hull transducer often intimidates DIY boaters, but the DST810 Gen2 prioritizes simplicity. The compact 0-degree design aligns easily with flat or gently angled hulls, and the 20-foot cable offers flexible routing. Fair the housing properly for smooth water flow, secure with marine sealant, and you're operational in under an hour. Routine care involves occasional paddlewheel cleaning to prevent marine growth—quick dives or haul-out wipes keep readings sharp.

Versatile Data for Informed Decisions

Beyond basics, it records depth up to 330 feet at 235 kHz, ideal for coastal charting or inland lakes. Temperature sensing aids in locating bait schools or avoiding hypothermia zones, while attitude data refines autopilot performance. Integrate with chartplotters for overlays showing speed trends, depth contours, and thermal layers, turning raw numbers into actionable intelligence.
