The Nikon Retractable Rangefinder Tether, in the TrueTimber KANATI camouflage pattern, was developed to help you safely manage the simultaneous use of binoculars and a ranging device. Its stainless steel spring retracts a 25" nylon-coated stainless steel cable into the case to keep a rangefinder or other accessory close at hand, yet secure and out of the way when not being used. Simply use the included split ring to attach the cable to your device or accessory and clip the tether's swivel carabiner onto a belt loop, a bag's MOLLE loop, or a backpack's shoulder strap D-ring, and you're good to go.
