-Maybe limit it to 500m for 2 seconds
-I'm not sure if getting helicopter names works at all, since i had the rangefinder on an autohovering mohawk for over 10s (I counted edit I think I was 700m away). I guess it was because I was on the ground, but I think the range at which a name is detected should be determined by where what you are trying to detect is, in relation to you.
--So if you are looking for a person's name, it is a shorter distance than looking for a helicopter's name, even if you are on the ground in both scenarios. If it is already like this, then it is broken.
