It looks nice enough outside, but is it warm enough to go swimming? For that matter, what is the temperature of the pool, anyway? With the La Crosse Technology WS-9029U-IT Wireless Weather Station, with its included waterproof probe, you will always know the exact temperature. This Weather Station is a great gift idea for tha person who has everything! It has a remote sensor (which can communicate with the station at a distance of up to 330 feet) which can be configured with or without the incuded ten-foot waterproof probe, this weather station can tell you the outside temperature and humidity, as well as monitor indoor temperatures. It is also an "Atomic" clock with a large display and your choice of 12 or 24 hour time readings. It can be free standing for desk use, or mount it on a wall! Both the sensor and the station use 2 AA batteries!
