How far are you ranging and how often are you getting hits without the extenders? I want to be sure I'm understanding the problem correctly, especially in an ELR context.
I am concerned with both these reports. I found no noticeable impact on ranging function with the extenders in the pre-production unit I have. Further, I found the range extenders to be a hugely value adding accessory. They really enable the spotting scope replacement function of the binos in a big way and were optically excellent. Hopefully these are isolated issues and not a design problem with the changes made to the range extenders in the production version. I think I'll shoot Philip an e-mail and see how things are going. The constantly fluctuating tariff situation has got to be a nightmare. I feel for businesses. Also, how is the optical performance of your extenders? Do you notice any added chromatic aberration, a degradation of resolution, or any performance issues near the edge of the image?
Lastly, did you try reversing which extender was on which barrel? I would be curious as the rangefinding components are only in one barrel of the binos and I wouldn't expect individual problems with manufacture of the extenders to effect both units.
