Make a compact addition to your expedition tool kit with the National Geographic Weather Station. This amazing weather station offers significant information and looks great too. It features a large, clear display with an alarm clock setting and it shows indoor temperature and humidity as well. There's a wireless transmitter which, when placed outside shows the readings for outdoors too. You can check the air pressure and there's an alert system that warns of particularly high or low temperatures. This unit forecasts the upcoming weather and shows sunrise and sunset times and moon phases too. If you live near the sea, it can even show the local high and low tide times and it features a time and date function which is regulated by the super-accurate atomic clock signal.
