Penetrator Fins are designed & developed in Australia by World Leading Specialists to give the best product to consumers who demand high performance from their equipment, EVERY TIME.
Penetrator Fins is the culmination of combining composite fabrication professionals with some of Australia's leading spear fishermen. Larry Gray the Founder of Penetrator Fins has been involved in the composites industry for over 30 years, specialising in providing high quality advanced composite manufacturing to the marine industry. Being involved with projects such as the Volvo Ocean Race, Inter-pacific 14 foot skiff championships, numerous National and International sailing campaigns he has the experience and skills required to provide the highest quality marine composites. These skills have been applied to the design and manufacture of Penetrator fin blades and is backed by over 75 years of combined spearfishing experience to develop the final designs you see today.
Penetrator blades have undergone the most rigorous testing that ANY brand can offer, they were not released to the market until its developers and testers were 110% satisfied.
Used by Australia's and the World's leading spear-fishermen and free-divers, Penetrator is thrilled to bring you high quality factory backed composite diving fin blades to suit all styles of diving.
Technical Overview – Penetrator Composite fin blades
Penetrator blades are manufactured using a proprietary Capillary Closed Molding System (CCMS). This system is a culmination of 25 years’ composites manufacturing experience applied to fin blade development over the past 8 years by Penetrator Fins founder Larry Gray.
The process eliminates the requirement for secondary processing materials used by other manufacturers producing an outstanding surface finish on both sides of the blade and reduces waste. These 2 outcomes alone produce a blade with a smoother flex curve and reduces the environmental footprint of the manufacturing process.
Penetrator Carbon Fiber blades receive a protective layer of Kevlar 49 multi-axial reinforcement in the tip of the blade to prevent chips and cracking.
This system is unique to Penetrator blades.
Kevlar is an extremely resilient and flexible material providing added impact resistance while allowing full flexibility of the blade tip.
Dual Action Water Channeling Rail
Penetrator Fin’s proprietary Australian Made EDPM water rail is then added with cyanoacrylate adhesive in purposed built pneumatic clamping jigs. This rail allows for greater control over water flow. The rail combines a "T" section to lock into the foot pocket and a water channeling section to guide water along the blade for increased efficiency and elimination of fin "wobble".
Data logger readout of cure cycle
All metal production tooling has been produced in-house utilising Penetrator Fins CAD design and CNC manufacturing capabilities. Mould temperatures are digitally controlled through the process to ensure the specially formulated resin system reaches its ultimate mechanical properties. Only certified carbon and glass fibres issued with a certificate of conformity (usually reserved for aerospace applications) are used. Full process control over these parameters ensures engineering performance measures are consistently achieved.
Penetrator fin blades are machined using the latest world class computer technology and CNC cutting equipment. This ensures consistent size and shape control to very fine tolerances.
