DESCRPTION 

Patented Dual Roller Trigger Mechanism – Zero Friction, Maximum Precision

Engineered for peak performance, this patented dual roller system delivers an exceptionally smooth and consistent trigger pull — even under extreme load conditions.

The mechanism housing (box) is created from a single sheet of stainless steel, with an additional welded plate forming three anchor points, ensuring secure mounting and structural integrity.

Key Mechanical Advantages:

  • The roller in contact with the shaft is free-floating, completely eliminating friction during shaft insertion.

  • The roller in contact with the trigger eliminates friction during the shot, providing a soft and smooth trigger release with no hardening effect under load.

Materials & Manufacturing:

  • Main body made from marine-grade AISI 316 stainless steel

  • Trigger crafted from a proprietary super-resistant alloy, hardened to 55 HRC

  • Shaft roller made from 17-4PH stainless steel, highly wear-resistant

  • Manufactured using high-precision 3D Metal Injection Molding (MIM) technology

Additional Features:

  • Rounded line release prevents wear or damage to shooting line

  • Opening angle of the line release: 65°

  • Tested to withstand up to 550 kg of load

  • Weight: 76 grams

Whether for professional spearfishers or high-performance custom builds, this trigger mechanism ensures frictionless operation, enhanced durability, and top-tier reliability in the harshest marine conditions.
