The unique, quick-release design of the Vortex Uni-Daptor lets you easily mount your binocular on a tripod or car window mount for extended periods of glassing. When you switch to free-hand glassing, there's no need to remove the Uni-Daptor from your binocular. The slim, lightweight design of this binocular adapter won't get in the way-or poke you in the chest. Designed and made in the United States by Jim White, the Uni-Daptor uses high quality machining and construction for a strong, secure fit.
