I have seen some quite spectacular claims for the length of the beam from these green laser pointer II models. I do believe that they do have quite a spectacular length of beam which is highly visible in the dark. You don't just get the spot, you get a full beam which just goes on and on, depending on the strength of the laser, sometimes for miles. It is a fact that a 200mW pointer beam is visible for 80 miles! When you are choosing which brand of laser to buy always ask about the warranty. If they only want to give 30 days - 3 months be a little wary because this would seem to say that they expect their product to break down.

Look for at least a 6-month warranty, that should mean that the product is going to be more dependable. If you are using a laser stronger than 5mW you would be well advised to use protective glasses. Most of these laser pointers are neat and small enough to fit into your pocket, they look almost like a pen.cheap stage lights

I believe another useful application for a green laser pointer II would be for hiking or any other type of outdoor activity, they would be great for finding your way to a particular objective. You could keep it always in sight when you put the beam on it. The green beam reflects off particles in the air and dependent on atmospheric conditions at the time or using, the beam can reach from 15,000 to 25,000 ft. The beam should only be kept on for under a minute at a time. With a 5mW pointer the batteries will last from 2-4 hours with normal use.Laser Pointers

There are some extremely attractive laser pointers which you can actually use as a star projector. There is a pattern cap which stays on if you want the pattern either directed on the sky outdoors or on walls and ceiling indoors. When you want to use as a regular green laser pointer simply remove the pattern cap. If you bought a good quality laser you could expect it to work properly and shine brightly for many years. Try to avoid dropping your laser pointer onto any hard surface because this could affect the laser's alignment and the alignment is necessary to a top performance.

There seem to be many countries which are putting bans on anything above a low strength laser. I think that you have to take these actions at face value, they would seem to indicate that there are too many irresponsible people using the pointers in a bad way. This is always a shame when the minority spoil things for the majority of people but this is what happens when people misuse this type of product.

There is no doubt that they can be dangerous in the wrong hands, particularly in the hands of children. You should never allow a child to handle a green laser pointer II unless strictly supervised.
