This is the chrono I have used for several years with excellent results. I don't connect the USB cable anymore & just note the FPS and pellet weight for each shot. These figures are then entered into this excel file that I use with the PC.
This data nay help some folks.

FPS = Feet Per Second, MPS = Meters Per Second, FPE = Foot Pounds of Energy. | |||||||||||||||||
To convert to Joules multiply FPE by 1.3558, Joules to FPE multiply by .7376 | |||||||||||||||||
To convert MPS to FPS, MPS x 3.2808399 = FPS . | |||||||||||||||||
To convert FPS to MPS, FPS x .3048 = MPS. | |||||||||||||||||
FPE Formula is Pellet weight (gr) x FPS x FPS divided by 450240 or 450436.7. | |||||||||||||||||
