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.
