Great Northern Bow Strings start with the best materials available for our strings and cables. Each strand of the bowstring goes through a tensioner to ensure exact size with no loose strands. The sizes are controlled with our precision lay up machine. This machine allows us to achieve accuracy in sizes down to one thousandth of an inch. While some string makers are willing to settle for "close enough" we believe that by maintaining the highest standards of quality, our customers can achieve the best results possible.
