Wild Traveler / Explorer-Adventure in the wilderness, guide distant targets and send distress signals to make your trip more enjoyable and safe.

Astronomy enthusiasts-For astronomical stars, the green high-power laser pointer beam is a very beautiful green line suitable for observation in the night sky and helps to indicate the position of the star.
