My dad works as a safety consultant/investigator for various chemical and shipping company's, in his job he often needs to point to things like stress fractures, load bearing points from considrable distance in full sunlight. Now i've been thinking about buying him a laser pointer for his birthday, but i have the following requirements;
Good visiblity of the dot at ranges 25 to 500m in full tropical sunlight (as far as possible without compromising the other requirments)
Absolute minimum of heat effects (Very very important safety feature) possibility of flammable gasses etc.
Very strong mechanical construction! Waterproof, Gas proof, Chemical resistance if possible are definate + points
I realise this is a demanding list, but which pointers come close.
