Unfortunately, the pool is not yet 82 degrees. (Monday it was 73.) The receiver, on the left, stays in the house, and the sensor, on the right, floats in the pool. It also has a digital read-out of the pool temperature. It was easy to set up, and from the kitchen window the receiver gets a full signal. Given the fact that T does not like to leave his thermometers in the pool all the time, this will come in really handy. It's also fun to watch the temperature rise on a sunny day and fall again at night. The receiver tracks three days worth of temperatures plus long-time highs and lows.
