JJOmaha Report post Posted November 13, 2021 I want to upgrade optics. I have a Nikon 10x42 Monarch binoculars with chest strap and 2 year old Vortex Diamondback 20x60-80 spotting scope with carrying bag and the original box I would like to sell. Any suggestions besides eBay where I can get it done reliably? JJOmaha Share this post Link to post Share on other sites
