Being military, I find myself needing to do lots of powerpoint presentations from large LCD TV's or projector screens. I need a pointer that will fit in my uniform pen loops, which means it needs to be very thin. A standard 13mm diameter laser won't fit. Needs to be about the size of a Cross pen... any ideas?
Different topic- some lasers don't show on a TV screen, yet I've read that others do. What's the difference to get a laser to show on a TV screen?
I really don't want a junky $3 thing that breaks and has a dim red beam.
