Hey has anywhere here tried measuring your tune using two microphones connected to a laptop? I heard if u place one microphone next to target and one next to barrel around 30 yards u can calculate velocity wo needing to buy expensive equipment. Just curious if anyone tried

@shambozzie You beat me to it! I use the muzzle mount version and love it! It would be nice if it calculated fps and not mps and it would also be nice if it displayed 10ths, but it does the job nicely for tuning.

There are also several chrony apps for your phone. It takes some setup, and I never had much success with them, but they work on the same principle of two microphones. The phone "listens" for the crack of the gun, and "Thunk" of the hit, and calculates the speed.
There is one major difference in this technique though. The measurement is the "Average" speed of the shot, not the speed at the muzzle or speed at the target. That just means that if your target speed is 860 at the muzzle, your measured speed will be lower, depending on distance to target.
Members looking for a low cost option seem to like the muzzle mounted model above, I have a Combro, Caldwell, and just purchased the FX chrony. highly recommend the FX. Yes, it's expensive, but I'm spoiled now.
Good luck on whatever method you choose.
