Already answered: sharing a glass with others, or possibly storing in a case.
Not according to my experience. Give it a try yourself and let us know what you found---you can use one of the tubes to experiment.
Who in their right mind carries a ruler into the field to set an IPD?
Truly, there is nothing in this world which is so simple that someone can't make it complicated.
Nothing.
I'm not trying to make something simple complicated. I just don't find that my experience always corresponds to those "Binoculars for Idiots" photos Dennis posted. There's often a range of settings where it looks more or less like a single circle to me... but if I'm not in the middle of that range, with roof prisms anyway, I'll soon get annoying little blackouts. Maybe I just need a systematic approach to eliminate them as Alexis suggested.
Not Bill Cook!
In his post #23 above he says that setting it is intuitive. When it is right you will know it and when it is wrong you will know it.:t:

I'd really like to understand your experience because I can't even imagine the problem relating to IPD. My face is not symmetrical so my lens centers for eyeglasses are adjusted accordingly. But the distance between my pupils is a straight line with a certain distance, so I have no trouble aligning each exit pupil and eye pupil when using binoculars.

I just adjust my IPD until I see a concentric circle. The picture on the left is wrong and the picture on the right is correct.:t:
Wow! I had no idea this topic would be of such interest.

Hi Lee,
I hope the advice you have received was that you need more binos, and more trips to use them.
Peter.
No, it was this...
Conversation with financial advisor:
Lee. it has come to my attention regarding the depletion of XX% of your financial assets to binocular procurement. As your financial adviser, I highly recommend that you no longer purchase any binoculars, equipment, and materials, etc. from Zeiss.......You will now purchase all your products from Zenray Inc., until the balance sheet is back in the red...
Lee-
But.....Zenray?
Just kidding, on this Friday.

Hi Lee,
If you set the IPD to 70mm then neither of your eye pupils will be aligned with the center of the EPs. The consequence is that you won't be able to see the right side of the field stop (assuming that the larger PD was for the right eye) and thus the FoV is reduced. If you align one of your eyes with one EP (by setting the IPD to either 66mm or 74mm) then you'll also miss the right side of the FoV, but a larger part of it than for the previous setting.

He certainly encouraged us to continue in the same way with our expenditure which is primarily on holidays to Scotland with a bunch of binos and cameras as often as we can manage it.

And how much did you pay for this advice? My 'financial' acumen is way low, and I could've suggested that!
