JGRaider,Mhoper5, Leica had numerous known issues with the Previous Geovids, particlularly the 40034 models. I had one and it wouldn't range anything past about 200 yards when temps got near freezing. Lot's of folks had that issue and it didn't matter if you had a fresh battery in there or not. I understand Leica fixed this issue, especially with the latter models.
I agree with you. How do I tell what model I have? I put fresh batteries in ever year and have never had any issues. My point on the battery limitations, yes I agree Leica had know issues. From what I understand they changed their technology to work with the limitations of the batteries. Less power hungry electronics. The flaw in their design was assuming full power would be available all the time.
