The T-REIGN Tracking Series Large Retractable Gear Tether is made in the USA by the company that invented the Original KEY-BAK key reel. The 2.5-Inch diameter case is made of rugged polycarbonate, the same material as bullet proof glass. With 10 ounces of retraction force, the reel will secure and organize your most trusted tools and electronic devices. Whether you are tracking a big buck or using your favorite call to draw waterfowl towards your blind, know that the tough 48-Inch Kevlar cord in your T-REIGN retractable tether will keep your gear secure while you are lining up the shot you will be talking about for years to come. T-REIGN products are put through tough environmental testing to make sure they can withstand the demands of the most rugged terrain in the world. Large T-REIGN Tethers have an innovative locking system which allows you to take the tension off the spring while you are using your range finder or GPS to make them easier for you to use. Attach the unique aluminium and stainless steel carabiner to any loop or D-Ring on your vest or pack.
