What's the least costly VISAIBLE BEAM green laser pen-pointer which can be seen in daylight. The bigger, brighter, most visible beam is most desirable. Actually, color doesn't matter; only visibility. I want to put the "machine gun" laser inside a 1/48 model airplane and match it with sound bytes, all triggered by one switch. I did it with a laser that was too weak and just put a dot on the wall and drove the neighbor's cat nuts trying to catch it. I'd be grateful for any help. May God bless and keep all of you, always.

Welcome to LPF. Any green Laser that you can see the beam on will be dangerous to anyone exposed to a direct hit or a reflection. The area around the model would have to be made Laser safe. Look into the safe guards required, and see if this is still something you want to pursue.
