The Diamond bow line started in Louisana with a small company that used the cams from bowtech, they have been in production for around three- four years now, Bowtech decided to buy the company out last year and keep the line going, they are nice bows .... Two years ago I had the chance to shoot four different models that they had at a get-together in Colledge Station Texas, that was held by Texasbowhunter.com...I enjoyed shooting the bows.
