The MantisX does an amazing job. It FEELS when the shot breaks. And it doesn't mistake racking the slide for the trigger press.Yesterday I tried timing [dryfire] reloads with a shot-timer app on my phone and could not get either of two different apps to correctly time the reloads to first shot. However, I need to figure out how to adjust the sound thresholds because there was too much noise to get anything usable. I'll continue to experiment. . .
It actually waits for me to reset the slide (locked back) and get the gun level (in front of me) - READY - It knows! - Before the timer goes BEEP. It then knows when I've broken the next dry fire shot to stop the timer. I don't know how they do it, but they do it very well.
Well, I sort of know how they do it... it's with gyros, not audio.
An impressive bit of technology.
