DESCRIPTIONĀ
Patented Dual Roller Trigger Mechanism ā Ultra-Smooth, Zero Friction, Structurally Innovative
This high-performance Patented Dual Roller Trigger Mechanism is engineered to deliver precision, reliability, and strength in even the most demanding spearfishing conditions.
Its innovative design features a housing (box) made from a single sheet of AISI 316 stainless steel, folded using a proprietary method that avoids any welding, while creating three robust anchor points ā including a third screw positioned at the rear for added strength and stability. This folding system also eliminates welds on the lateral wings used for screw fixation.
ā Dual Roller System:
-
A floating roller in contact with the shaft eliminates friction during shaft insertion for smooth reloading.
-
A second roller in contact with the trigger provides a zero-friction shot, ensuring the trigger pull remains light and does not harden under load.
-
This results in an effortless, precise shaft release.
