This happened to me 2 times in 2 weeks. I was shooting 3d and at full draw on two targets on two diffent course my pins went black, no illumination from the fiber optics at all. I was in a pretty shaded area both times but other shots on the courses were equally as shaded.
I shoot a copper john with .019 pins. I know this is abnormal since it has only happend twice and have never had any other problems with the sight. Just wondering if this has happend to any of you guys.
It isn't the best thing to add what the He@@ just happened to my pins to my shot sequnce.
