C4 Flap VGR Fins
C4 Flap VGR Fins
  (Enlarge)  
The first and foremost objective of the new Flap VGR T-700 is to reduce any waste of energy thereby maximizing safety so important to freediving. The new C-4 composite carbon blade will flex using 75% less energy than conventional blades. The water channels down the face of the blade and the Flap increases propulsion by incrementing the blade surface and the flow of the water over the blade through the tip.

In our opinion the Flap may be a more efficient fin but it’s not for everyone. We feel the “Flap” protruding from the front of the blade could be a virtue for an open water diver and a disadvantage for divers prone to hitting the bottom of their fins on the sea floor.

The new VGR (variable geometry rails) blade offers a 40% increase in structural strength compared to the standard T-300 model. With a standard carbon blade the outer layer is subjected to a wider curvature and stretching than the inner layer which is subjected to more compression, consequently increasing the cause of breakage.

Thanks to the new flexible fibers the new T-700 offers 40% higher tensile strength thus avoiding breakage due to high external stretching and high internal compression. The C-4 Fuego VGR blade extends all the way to the heel which distributes the flex and the weight load to which it is subjected. This ensures the best degree of performance coupled with lightweight structural resistance.

The advantage over the C4 Flap is reported by C4 to be 15% over the Falcon. A diver can therefore expend the same amount of energy for a more efficient return of power and thrust.

· Every C4 Flap blade is marked individually with the guarantee number on the back of the blade.
· The C4 Flap fins – VGR are available in three grades of stiffness: 25 (soft),30 (medium) and 40 (hard)
· The C4 Flap blade dimensions are 780 x 190mm (31”x7.5”)
· All carbon fiber C4 VGR blades are made from 100% carbon T 700
· Two Year Guarantee

Choice of stiffness
Flap blades come in three grades of stiffness: 25 Soft, 30 Medium and 40 Hard in order to suit all different types of uses.

A soft blade will complement a dive in not too deep water where a sudden burst of speed is always required thus offering a relaxed and comfortable dive and good management of precious oxygen.

A harder blade will give the extra boost of power required from a hurried ascent in deep water or from a sudden change of direction or a swift U turn. In these occurrences a hard blade will offer the best chance for a safer and more productive dive.

Nonetheless a hard blade will take its toll on oxygen supply with only a moderate increase in speed and overall performance.

Pair comes with Omer Millenium foot pockets.
