What is a Brightest Laser Pointer color?

Everyone has heard of campers and hikers who get lost in the woods. The stories are often harrowing, as search teams have to trek through thick forests and mountains without finding the missing person. More and more campers and hikers are using powerful lifesaving hand-held lasers. If you get lost in the woods at night and have a powerful laser, you can send a signal to a search party miles away. They see the source of the beam, narrow down their search and start heading towards you. If there is a search vehicle in the distance, you can let us know of your presence. Most recommended green laser pointer designators provide fixed focus or focus output. If the laser has a fixed focus, it means that the width of the beam itself (getting wider or thinner) cannot be changed. It is usually standardized from 1.5mm to 3.0mm openings, but always remains at that particular width. Focusing lasers (as you might expect) allow you to enlarge or shrink the beam. So, you might ask, what are the benefits of using a focable laser versus an unfocused laser? Simple. More beam control.
