Ok, for anyone interested, here's an update. Yesterday, I contacted CED about my problems with the M2 chronograph and quite frankly, the customer support has been phenomenal. I spoke with a very nice lady (Supaporn). She asked lots of questions, offered advice and told me to expect an email message within the next few hours. When I got home from work, the email had arrived with several attached files and a drawing.
Early this morning I received another email message from Charles, explaining that he is currently traveling internationally and apologizing for the delayed response. He also offered tips but asked several question regarding shooting conditions, set-up, temperatures, speeds, etc. I answered his questions and he responded within an hour. He thinks the distance I'm setting the sensors from the muzzle is to close. I won't get a chance to give his suggestions a try until April 16 but he asked I contact him immediately following my next range session.
I guess I'm not familiar with kind of tech support. This is great and expect with this kind of support the problem will be sorted out shortly. I highly recommend this company when you begin shopping for your next chronograph. Amazing!!!!!!
