My brother and I are currently working on an air launcher projectile. It is highly likely that it could go .5 to 1.5 miles. We have the ability to test at this distance, however locating this costly projectile is likely to be difficult. We have looked into gps trackers, however the cheapest one that would actually work was 500 dollars and if we had that kind of money we wouldn't need a gps tracker on the thing in the first place. I just wondered if there was a quick and dirty way to make a short range locator. I have heard of little bluetooth tracking stickers, but I wasn't quite sure if that would work to find a 1 foot long projectile in a square mile field. This locator needs to be extremely shock resistant, fit in a container 7" by 1.5" and must weigh a minimal amount. We also are looking hopefully below 100 @most 150 dollars.
