DIY rangefinder
 
I figured that with the growing number of long-shot First Strike players out there, and with laser based ranging systems still in the $200 range, a $20 DIY project is long over due. This is the same basic technology that used to be common in rangefinder cameras and it works by presenting two images that over lap at a given distance. No batteries required and you can probably build it from household scraps.

It looks little slow and inpractical for paintball.
But it is interesting.

They work alright for rough distance guesses. I have an old camping one that used to be used for ranging when hunting.

If you've work in surveying, go into the back equipment room. They'll be there in the "cool, but never used" bin buried under a bunch of stuff. I'd take pacing as a more accurate measure than these. A "dialed in" pace can be pretty accurate. At least, given my experience with the optical rangefinder in my car trunk.
