Unlock Precision Boating with Advanced Speed and Temperature Sensing

Imagine gliding through the water with pinpoint accuracy on your vessel's speed, even at those tricky low speeds during docking or trolling. The Raymarine ST900/P17 stands out as a game-changer for marine enthusiasts, combining a high-performance Gen2 paddlewheel with fast-response temperature sensing in a sleek, low-profile thru-hull design. This long-body plastic sensor delivers reliable data to keep you informed, whether you're racing, cruising, or fishing.

Key Advantages for Everyday Use

• Superior Low-Speed Accuracy: Starts logging speed from just 0.3 knots, perfect for precise maneuvering in marinas or slow drifts.
• Extended Speed Range: Smooth, linear performance up to 45 knots ensures dependable readings across all conditions.
• Quick Temperature Feedback: Captures water temp changes rapidly, ideal for spotting baitfish zones or monitoring engine cooling.
• Retractable Design: Pull it up easily for cleaning or winter storage without hauling the boat—saves time and hassle.
• Versatile Analog Output: Seamlessly integrates with a wide array of Raymarine displays and legacy setups for straightforward upgrades.

Crafted with durability in mind, this sensor's plastic housing resists fouling while maintaining a low drag profile that won't disrupt your hull's hydrodynamics. Boaters report fewer false readings and more consistent performance compared to older paddlewheel models, making it a smart choice for both recreational and competitive sailing.
