In 2010, after an accurate planning work which foresees a structure with 6 different thickness, two years of tests and the realization of 8 prototypes, was born the shovel PROPEL.
The material of carbon Prepeg worked in autoclave of pressure and temperature of aeronautical level confer on the shovel extraordinaries characteristics of resistance and elasticity. A product of big quality with an interesting price.
From the experience with PROPEL today is born the PROPEL HOLE.
But what have more the Hole since materials and formalities of working are the same?
It has more only a hole.
It isn’t easy suppose which only a hole can improve the performances so significantly, and yet it is just that empty which allows of downloading the part less active of the shovel concentrating the effort in the apical zone where the coefficient of elasticity is maximum.
With the hole we reduced the surface less reactive of advantage of the apical zone more high-performace.
Result: the best dynamical answer with less difficulty. Even from first dives it’s evident how the lower use of oxygen is an advantage for the apnea.
