Hi Jim,
Is that the large loupe that has the slide attachment at the bottom? The case is also round in shape about 5 plus inches long?
Anyway, it's a GREAT loupe and is very easy on the eyes with extended use.
I also use the Toyo loupe and a Horseman 7x model.
My favorite version is the Toyo 3x but that may have to be upgraded to the 7x Horseman model as my eyes start worsening with time.
Had one of the little Schnerider loupes but just couldn't get a good hold on them. So, off they went.
Lots of different models out there... it's just a matter of what you get use to over time.
Cheers
