Shot Timer is a great gun training aid for dry fire practice or take it to the range for live fire practice. Works for all caliber rifles, pistols, shotguns, and even air rifles. This is not for competition and it’s not perfect so please be kind on your feedback. I’ll be spending a great deal of time testing and adjusting Shot Timer so please send me constructive feedback and look for updates soon.
