Deluxe Floating Thermometer

This product for a pool is a device that floats on the surface of the water to provide a quick reading of the temperature. They can be designed to float freely or tethered to a ladder or other objects to keep them from floating away. Floating thermometers often come with a string or rope for tethering. Some have a long design to prevent them from getting caught in a skimmer. They can also display the temperature in either Fahrenheit or Celsius.
