Hi @Ham1960 - Thanks for reaching out!
We are hopeful some others in the community who have talked about binoculars will be able to share their advice with you.
My binos are on the kitchen table and are used everyday. 🙂 We (my wife and I) are trying to track banded birds and we can see the front feeders from the kitchen. We also have a backup pair in the car, in case the normal pair is accidentally left home or if someone needs to borrow a pair on a bird walk. In the winter time, the birding scope goes into the trunk of the car, since over wintering waterfowl can be seen on local lakes.
I did make the mistake once of leaving the binos near an AC unit at a hotel, and somehow the blowing air fogged the insides and they had to be sent back to the factory for fixing.
