As beetroot says, the Xero is very convenient and no chore at all to set up. Previously I used an optical chronograph, which I learned to set up very quickly. But the Xero is a simple matter of placing on the bench in an appropriate spot. It's that straightforward. I used it each time and chronied over two cases of Lapua in addition to some RWS and Eley.
If my Garmin was lost, I would immediately get another.
