Good buy on a chronograph, and a couple suggestions.
Kelly J--
want a good one that will work indoors or out if possible, all the pertinent readouts, maybe even one that can print out a hard copy of the shooting event, with a summary of the results.
Seems what you want is a Shooting Chrony Gamma Master model. It's the one with all the bells & whistles, works indoors, outdoors, sunshine, shade, anything but rain. Prints a hard copy of the speed in fps or mps of each shot, then for each string does the math and prints out: Highest velocity, lowest velocity, average velocity, spread between high and low, and standard deviation from the average.
It's just a little tricky to set up and make it do its measurements and math right; I haven't used mine enough to feel familiar with it, and the users manual was written FOR those who already understand the thing BY those who already understand the thing. Kind of frustrating for the newbie.
However, when you get it all right, it prints each shot velocity automatically as you shoot, then does its math and printout neatly on command @ the end of the string.
Thing of it is, it doesn't cost an arm and a leg, just an arm. But you don't have to write anything down; no fooling with a calculator @ the range, the chrony does all that kind of work and you concentrate on the shooting. For me, it was well worth the extra.
One good idea with any chronograph which uses little steel legs to support sunshades over the sensors: Replace the supplied steel legs with thin wooden dowels. That way when (if?) you shoot the leg, it just breaks rather than breaking its plastic socket in the sensor unit. And thin dowels are cheap to replace.
I bought a cheap camera tripod to support my sensor unit--beats the bejeesus out of trying to position it correctly, on a box or some such.
