I don't know if any of you guys have had this problem ? When i try to use my bino's that are on my harness,with one hand the bino's fold closed. The question im asking is there a product out there that keeps the spacing between your eyes adjusted on the bino's.

Same issue, but no solution other than loosening up the straps or holding binos with 2 hands.

The only one i know about is made by Vortex Optics. Its called the "Binoc Loc". Your binos will have to have a tripod adapter socket. It sells for $25. Here's the link. There's a short vid that shows how it works at the link.
