we use a prochrono chronograph, at our club very easy use as long as you can use a calculator or you can always cheat and find a velocity conversion chart

but these little things go for around the £100 mark (inc del)

and if you want to push buttons and see the fancy things it does instead of just reading the shot to shot readings, theres pleanty enough to keep you busy on these long summer days


though i not been able to use any others bar chrono, i would rate this bit of kit pretty damn high!

hope this gives you a little more to think about

all the best
