I just purchased a pair of Bushnell 8x42 Legend Ultra HD binoculars. They are great, and very clear. My only concern is that they make a funny noise when they are turned up and down. It sounds like a bearing sliding up and down. Has anyone ever had this kind of issue? It doesn't seem to have any effect now, but I'm concerned about the future of them. Should I just send them back to Cabelas? Thank you for any come backs.

That's what I'd do.
