AJ, Yeah, it was a frustrating experience to not have that M2 work. I may have gotten a bad unit, but we switched around everything that could be switched around and checked and rechecked and when it did work, I had ES well over 100fps--typically 17-25fps ES over the Oehler. If I would take the middle third, in terms of speeds recorded, and average them and input them into Exbal, actual shooting seemed to agree with the aveage MV calculated that way. That's the same thing I had to do with the the really cheap chrono in the past. That just doesn't seem to happen with the Oehler (there also happens to be a world champ 1K Palma shooter that works at the range that uses this Oehler I'm speaking of to check his load and he believes it's working fine).
In terms of lighting, the day I used it, the unit was completely shaded, albeit a bright sunny day. I think I have a pic of the setup.
Maybe I messed up somewhere, but chronos are not that complicated and this is not the first one I've used over the last several years.
Maybe I just got a bad one? I don't like to speak poorly of a manufacturer, but will relay my experience.
