We setup my chronograph on Friday and failed to get accurate readings. We got some very crazy numbers and the display was blinking which indicates something is not right. I think the culpret was the low angle of the sun, we setup about 2.00 pm which I thought would have about max light but the sun was pretty low on the southern horizon. Put in fresh batteries, tried with and without the diffusers. Even tried two 35P bodies but no good. Anyone have any experience with similar situation. Bullets were .22 and .30 spitzers.
