Fin Blades - T700 Naked Carbon Fibre (Hawaiian Whales)
The ultra lightweight T700 Carbon fins are an elite high performance carbon fin, that are softer, lighter, stronger and more responsive to the parabolic curve that happens with correct finning technique. This means that the spearfishing diver exerts less energy to perform the dive up and down. With reduced fatigue, divers who have been trialing the fins have found that they are able to catch that dream fish, as they have more energy due to the lightweight nature of these fins. Also great for the freediver who wants to explore new depths.
Penetrator Carbon T700 range offers the ultimate in fin performance. Identical profile to our other blades, 72 cm working blade length, 25 degree toe angle for efficient surface fining and extremely lightweight at 200 grams all fitted with our exclusively produced wide water channeling rails. This means less fatigue and lower oxygen consumption for divers who appreciate the advantages that can be gained from high performance equipment.
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.
Carbon 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.
Once moulding is complete fin blade profiles are CNC machined to an accuracy of .01mm. Penetrator Fin’s proprietary rubber water rail is then added with cyanoacrylate adhesive in purposed built pneumatic clamping jigs.
