The little rings and tie downs to attach my Nikon Monarch were enclosed, but there were no diagrams or written directions to get them attached.
I had been warned to by a Nikon harness because of attaching issues.
I figured it out, with the help of birder colleagues, but directions would have been appreciated.
Also a nuisance that California sales tax didn't seem to be charged, so I have to save receipts for tax time next year to pay "use tax."
Pros: does the job, easy to use
