If I had a sure way of preventing them from going off I might carry one around.

Unfortunately, lasers are inefficient, which means they deplete small batteries very quickly. Any handheld laser powerful enough to be fun is a liability and has few practical uses. Lasers really are useless in daily life and if they weren't so pretty this hobby wouldn't exist.

That said, if I were to carry a laser on a keyring, it would have to be absurdly powerful for its size. Like at least 1000 mW. A red diode is a good candidate because they are relatively efficient and bright.

Well I guess it depends on the person. Personally I could have just as much fun with a 5mw as a 5w.

My favorite lasers are 50 mW or less (color is more important than power). Honestly, I kinda don't like class IV lasers because I value my eyeballs. But a keychain laser just seems like it should be an abomination.

I think Barnett lasers sells some small ones, but may be too powerful for your liking.

I love my single mode 505's - 520's and my 488's as well as 405's and especially during late fall and winter when most the leaves fall off and can target trees hundreds of yards away.

Have you ever looked at your lasers spot/termination hundreds of yards away through a telescope ? It's very interesting and not a little round spot at all.

Now the challenge becomes to make it a little round spot, try a dpss laser and a beam expander, now look through your telescope again.
