B1 doesn't fit Leica 10x42 3200.COM

The MAGVIEW B1 adapter is definitely a welcomed digiscoping option that I was excited to use. It is sleek and easy to use. The quality is great. However, I made an assumption about the B1 fitting my primary binos and was wrong. Measure your eye cups prior to ordering! There are two B1 options for MAGVIEW - B1 and B1 XL. Guidefitter only offers the B1.

I was unable to install the B1 on my Leica 10x42. The B1 is too small and will not fit over the eye cup.

The B1 did fit onto my Swaro 15x56 eye cups.

Also, note that once the B1 adapter is installed over the bino eye cup, the other eye cup will need to be adjusted out/up, one turn, to be even with the B1 adapter side. I prefer to glass with my eye cups all the way in/down, so it'll take some getting used to.
