BG, the F1 is kind of the starship for arrows. What isn't working? Do you have the light kit? I found the light kit makes a huge difference for getting accurate repeatable readings. I didn't buy Chrony's, I just bought two lights from Home Depot. The little cheap ones with the 10" aluminum reflector around them. I hang those above the plastic white tops and I have not had any issues since.
i am having trouble with it reading the arrow inside. it takes three shots to get a reading. i put it under a light and tried a clamp on light, but no luck. i will have to try home depot
