Review RAYMARINE Airmar Water Speed Sensor fits ST800

The Raymarine ST800-p120 AirMar ST800 Water Temperature Sensor is an advanced marine technology device designed to provide accurate and reliable water temperature readings for anglers, sailors, and boaters. This sensor is part of Raymarine's ST8000 Series multifunction displays, which offer a wide range of features for navigation, fish finding, and weather monitoring.

The ST800 Water Temperature Sensor is equipped with the latest AirMar technology, which uses a transponder buoy that communicates with the display via a wireless signal. This design eliminates the need for cables or transducers, making installation quick and easy. The sensor buoy is also designed to be buoyant and can be easily retrieved if it falls overboard.

The ST800 Water Temperature Sensor is highly accurate and offers a resolution of 0.1 C. It is also capable of measuring water temperature in real-time, allowing users to quickly and easily monitor changing water conditions. This information can be invaluable for fishing, as it can help anglers locate schools of fish that are holding in specific temperature ranges.

The sensor is also designed to be durable and resilient to the harsh marine environment. It is constructed from high-quality materials and is rated to IPX7 standards, making it resistant to water, salt spray, and UV radiation. The sensor buoy is also equipped with a long-lasting, replaceable battery, ensuring that it can operate for extended periods of time without the need for frequent recharging.

Installation of the ST800 Water Temperature Sensor is simple and straightforward. The sensor buoy is easily attached to the boat using a secure mounting bracket, and the display is configured using the Raymarine Lighthouse user interface. Once installed, the sensor provides real-time water temperature readings directly on the display, along with other important data such as speed, depth, and wind information.

Overall, the Raymarine ST800-p120 AirMar ST800 Water Temperature Sensor is an essential tool for any serious angler, sailor, or boater. Its advanced technology, ease of use, and durability make it an indispensable companion for anyone who spends time on the water. Whether you're looking to catch more fish, navigate safely, or simply enjoy the beauty of the ocean, this sensor is the perfect addition to your marine electronics setup.
