i bought the shooting chrony beta master december 30 09, i got home and set it up and tried shooting some elastics through it for over an hour and got maybe 3 to actually read. i got frustrated and closed shop and went to bed. the next day i brought it with me to work to play with and never had time so wife and i went to the range new years eve and i tried to use it. i was getting errors from the second i turned it on, spent almost an hour messing with it trying different lights, with the shields, without. all to no avail. it was cold out and the unit was in the truck for about 2 hrs or so prior to use, i havent tried it since. i want to return it and buy another, but i read so many good things about the unit.
from what i can decipher in the manual it pretty much is a turn it on and shoot. if i am wrong, please tell me so i can use this dam thing
