I trust any Shooting Chrony about as far as I'd trust a crack addict.
Just got a Labradar and so far it's impressive. For an inexpensive light-screen chronograph, would recommend the ProChrono Pal. For a really not schict chronograph would recommend the Oheler 35P, partly because it works very well, and partly because it provides a double-check of every velocity--which is appatrently why Bryan Litz now uses TWO Labradars.
Excellent write up.
I though that Brian used equipment that he made himself tp record over a 600 yard spacing. At least that is what he said years ago.
