I would also say if you can send it through with a checked bag, and either way remove the laser head, and if you have it install a flashlight head assuming it was built using a flashlight body.
Rifter, how humane of you, I would be temped to demostrate to that person what a laser pointer to the eye is like, perhaps with my 3.5 watt 445 nm laser
I am just getting back into the laser hobby after a multi-year absence with my first purchase of a multi-watt 445 nm laser, and I am interested in trying to use the EG&G Electro-Optics 460-1A that I bought on ebay a while back to confirm its output, etc.
Now for the problems I know I need to do...
