I automatically take the strap. On the buttons, I could be wrong but I think there is a lock time in the settings? Worth a check as mine locks with seconds.I'm liking mine, using it for most rounds now. It usually misses a shot or two a round but pretty good overall. GPS accuracy not bad either, I'm definitely not having to manually adjust as many shots as before. (although its a bit more hit and miss on the green)
Main issue is just the control buttons getting pressed by accident.
