Sorry I should have sent both guns to Nasa to have the test done, spearfishing is such a precise science ! But my intent was to say the circular band adds power not the open muzzle, the master America has an Open Muzzle but with a split band. What was surprising to me was the amount of power that you gain by using a circular band. I also agree with the open muzzle being a pain on the boat.
