I have a new pair of Swarovski 8x30 CL binoculars. I'm having a problem where the diopter adjustment shifts with altitude. I live at 400' elevation and both eyes focus correctly with the diopter adjustment set right in the middle when i'm at home. However i also work as a fire lookout at 8800' elevation. When at the tower i have to readjust the right eye diopter way into the negative to be able to focus both eyes correctly. Once i've readjusted the diopter i'm good for the day until i return home and have to reset. What could be causing this? Otherwise i'm very pleased with the binoculars and the views they provide.
I have a pair of Leica Ultravid 10x32 that i also use at home and at elevation and they do not require readjustment between the two locations.
Thanks for any comments or suggestions.
