The laser appeared on the target, moved through an ark across it & then disapeared again. I haven't done the paper trick, but will try that when I pick it up later in the week.

Hey there Bryan
Are you absolutely sure that the laser, itself, is collimated? They are notorious for not being so.
Cheers
