The design of the Collins gun has been carefully created over the years by master freediver Edgar Collins and his family and friends. He has been spearing since he learnt to swim off the far north coast of Queensland, Australia, and since then he has extended his reach not only to the rest of Australia, but to the waters of California, Mexico, Morocco and even the cold seas in Northern Europe. He has designed these series of guns because he could never seem to get just the right weapon to do the required job. Therefore, after years of on-deck discussions, target practice and sea trials, he has designed a series of guns that will more than fulfill the essential requirements of the serious hunter.
