Figured this was the place to put this. I recently built up a new gun. Hurray for friends who dont want a gun after it eats a couple gears.
Anyways, I have a Chrony F1 and a Madbull Revolution V2 and cant get a reading from either. Neither will even act like a projectile has gone through. Both are currently being used indoors as it got up to 10 degrees today. I am also shooting white BBs through them as my .20s are white. Batteries are fine in both.
Any suggestions on how I can get these things to work?
