I have a strike force V-drop. I used the tester fob and it has clearance. When I shoot the vane arrows i do not have a problem. They hit in the center and the arrows are in the target straight. Then when i switch to the fobs they go about a foot low and about a foot to the right. The fob pops off with the nock still atached and lands about 10 feet to the right and about 10 feet behind target. The arrows are in the target sideways. Looks like I am shooting about 15 feet to the left of the target instead of straight on. The fobs are smaller then the vains. Any help?
