Good as a guage. If you put a metal pan as your Target and you measure accurately, it will take readings. I used it to test different ammo on a gas ram and on a PCp with adjustable power. It's not perfect but it does work and give you a pretty good idea of what velocities are. I returned my shooting chrony F1 deluxe because I couldn't depend on it to give me anything but an error. If you measure things and adjust things and get your microphone adjusted this is great at 15 yards.

Very good little app. It works based on hearing the report the airgun makes when it fires and then the sound the projectile makes when it strikes the target. As long as you input the correct distances, it can give you a decently accurate reading. Using my Crosman 1322 (pump), I got a speed of 442 fps with 10 pumps and 499 with 15 pumps (makes sense). It also gives a muzzle energy readout if you put in the pellets weight (which is nice). Good Job!

Fairly accurate ... Very usefull for those airgunner who doesn't owned a chrono (like me) .. atleast I can optimize the output for a particular barrel and pelet. One glitch, sometimes it gives me error message without indication what went wrong. And it is better for short distance with metal target and no silencer because it is sensing the sound.
