Laserscopes need biannual tuneups and a touchup every roadtrip. They soon die if not PMed correctly. CVLs and CuBRs and argons over say 300 mW need tender loving care. Not to mention extension cords that cost between $2.00 and 10.00$ a foot to make.. In other words, some skills and effort.
Something you stick a pair of A123 or AA cells in and get 600-700 mW that is easily hidden in the palm or your hand and is controlled by a protruding button, and activated as easily as a TV remote by a three year old is a far greater hazard.
