Todger is right. The "old" bog standard laser pointer was just about powerful enough to point at things about 50ft away. Very useful during presentations too, they were. I know, I had one but, boy, did it eat up batteries. The cheapo ones that used to be on sale in markets/car boots/etc were really high powered Chinese pointers that could blind people at vast distances. I seem to remember one being pointed at the moon and it's reflection being recorded for a TV programme - you couldn't do that with an older type.
