If buying a chrono on a budget, the ProChrono Digital is a great option, IMO. If not on a budget, and it suits your needs, I love the LabRadar.
^^
Have owned prochrono, then used Oehler 35P for years, went to Labradar this year, game changer.
You can drag it out anywhere, set it up in a minute without worrying about calling a ceasefire at your range, and get data. You can take it anywhere and set it up anywhere.
The optical chronographs seem to prefer overcast days, no matter what sort of light shields I rigged up around them.
Labradar is expensive and on top of the initial expense I needed the remote mic to get reliable readings, plus the $35 sight various people sell on Amazon to get it aimed right, plus a tripod and QR plate for the tripod.
