Composite Fins
Penetrator Composite blades are manufactured from Glass Fiber and Epoxy resin; using the same advanced vacuum molding process and high temperature.
Here are some key specs and features:
| Specification | Value / Detail |
|---|---|
| Blade Material | Composite: glass fibre + epoxy resin. |
| Manufacturing Process | Advanced vacuum moulding, digitally controlled high-temperature cure cycle; CNC-cut profiles. Ensures accuracy and consistency. |
| Blade Sizes | They provide different working lengths: e.g. 72 cm for full-size Ghost model; smaller “620” version ~62 cm for smaller framed divers. |
| Blade Width | Approx 19 cm |
| Insert Length (where blade meets foot-pocket) | ~14 cm |
| Blade Angle to Foot Pocket | ~25°, which affects how the blade aligns and where power is most efficiently applied |
| Weight (bare blade) | For composite Ghost 720 (72 cm): approx 395 g (medium stiffness) and ~345 g for a softer version. For the smaller 620 version composite: ~280 g. |
| Stiffness Options | They have multiple stiffness grades (soft, medium, sometimes others) so divers can choose what works for their strength / depth / style. |
| Warranty | Composite blades carry a limited 3-year warranty against blade breakage. |
They offer a progressive flex along the blade for efficiency and are super durable! These are the ideal fin for all round shore based and boat freediving and spearfishing.
Blade Angle
Penetrator sticks with 25° because it’s a good balance between surface comfort and efficient vertical kicking, especially for freediving and spearfishing.
Rails or Ribs
Color of rails or ribs are already fixed and cannot be changed anymore. If in case you want other rail colors this is upon request and and will take around 1-2 weeks availability. Colors available: Black, White, Red, Pink, Blue.

STIFFNESS
Choosing the right blade stiffness for freediving fins really depends on personal preference and diving style. However, as a general guide, we provide recommended stiffness levels based on body weight to help divers choose the most suitable option:
