Long time spearfisherman and competitor, I used a large selection of very good products but I wanted a speargun that made no concessions. I made a speargun that would not float or sink. I designed the speargun so the bands, the shaft and the hand holding the speargun were on the same level. This avoid the all too common loss of stability during release. Lastly, I produced a mechanism that is incredibly strong and smooth.
I have been competing solely with my products since 2009 and I managed to win the North Atlantic Spearfishing Champion twice. The added range and precision really helped.
