Raymarine ST69 transducer

Raymarine ST69 Speed and Temperature Transom Mount Transducer

Unlock a new level of precision and performance on the water with the Raymarine ST69 Speed and Temperature Transducer. Engineered for reliability and accuracy, this essential piece of marine electronics provides critical data directly to your Raymarine instrument displays, empowering you to make smarter decisions whether you´re racing, cruising, or fishing. The ST69 is the ideal solution for boaters seeking to add or replace speed-through-water and temperature sensing capabilities with a simple, robust installation.

By accurately measuring your vessel´s speed through the water, the ST69 allows for optimal sail trimming, precise performance analysis, and efficient fuel management for powerboats. When integrated with a GPS, it enables your multifunction display to calculate the effects of current, giving you a complete navigational picture. The fast-response temperature sensor also provides valuable information for anglers looking to identify thermal fronts and target specific species.

Key Benefits:

* Enhance Sailing Performance: Achieve superior sail trim and tactical advantage by monitoring real-time speed through the water, independent of GPS speed over ground.
* Optimize Fuel Consumption: For powerboat operators, identifying the most efficient cruising speed based on live data can lead to significant fuel savings over a season.
* Improve Navigational Awareness: Understand the true impact of tides and currents on your vessel by comparing speed-through-water with your GPS-derived speed-over-ground.
* Gain a Fishing Advantage: Locate productive fishing grounds by monitoring surface water temperature changes, helping you identify thermal clines where fish congregate.
* Durable and Reliable Operation: Built to withstand the harsh marine environment, ensuring consistent performance and longevity for years of trouble-free use.

Main Features:

* High-Accuracy Paddlewheel Sensor: A proven and effective paddlewheel mechanism delivers reliable and consistent speed-through-water data across a wide range of speeds.
* Integrated Fast-Response Thermistor: A built-in temperature sensor provides immediate and precise water temperature readings directly to your display.
* Robust Transom Mount Design: The unit is specifically designed for easy and secure installation on the vessel´s Transom, making it suitable for a wide variety of hull types, particularly on planing or semi-displacement powerboats and sailing yachts.
* Protective Kick-Up Mechanism: An intelligent safety feature allows the transducer bracket to pivot upwards if it strikes an underwater object or debris, preventing catastrophic damage to both the transducer and the transom.
* Seamless SeaTalk¹ Integration: Connects directly into the Raymarine SeaTalk¹ network for simple plug-and-play integration with legacy and current compatible instruments like the ST60+, i50, and more.
* Aquadynamic Housing: The low-profile, hydrodynamic shape of the transducer minimizes drag and turbulence for the most accurate readings possible while underway.
