Check out this new product that one of my clients has invented. It's called target cam and can be found on targetcam.net (if a blue could help with the link). It's a targeting surveillance system that provides instant feedback after each shot. This allows you to calibrate your shot without a spotter or having to walk 900 yds.
You're not wrong sir. It's pretty cool though. He just brought one of them in and showed me how everything works. If I did any long range target shooting on a regular basis I would use one. He also has customers who use them to set bait and hunt.
