Geronimo has the same features and technical refinements as Geronimo Pro: the difference lies in the barrel, which has a traditional circular section bore. The grip comes with a brand new adjustment system that makes it possible to personalize its size according to the diver's hand. The trigger can be adjusted both while moving and to make the release gentler, and mechanically activates a new kind of concealed line stop. There are two safety catches placed on both sides of the handgrip so they can also be activated by left-handers. The grips are made from soft-grip material to optimize purchase. The new muzzle can hold both circular bands and the special standard bands, complete with a brand new, patented pivoting bow system that blocks the shaft against the barrel right up to the moment the gun is fired.
