I heard of cases when people who had been wearing portable electrical devices like iPods, hands free devices for their phones had been hit by lightning. Being hit by a lightning is very dangerous (it can even be fatal) and some smart people have created this wonderful gadget. The Lightning detector will aware you if there is any storm that is closer then 40 miles from you. If a storm is 40 miles away, you will hear a buzzing sound. As the storm gets closer and closer, you will see different LEDs turn on to worn you about the storm.
If the storm is in a range of 20-40 miles one of the LEDs will turn on. The second one will turn on when it will be 12-24 miles away and the last one will turn on when it is 6-12 hours away. In that case, you should think of where to go to save your life.
This gadget can certainly help you save your life but as long as you don't wear any electrical device or any metal thing you should be safe. In other case, I would advise you to go inside any house or office or a store. The Lightning Detector is certainly useful for personal use. How about the electrical things that are in your house? You can certainly use its information to save them too.
You just need to unplug them all and detach the antenna from your TVif you use the external one. Besides, you should stay in a room that has fewer windows in order not to get hit if the lightning storm is very strong.
