Cetma Composites produces a range of high efficiency, fully scientifically engineered carbon freediving and spearfishing blades.

Mantra CWT, sister of Mantra, has been specifically designed for constant balance, therefore for pure freediving.

In this blade the stiffness distribution has been studied with the aim of minimizing the fatigue on the calf and tibia muscles.

Furthermore, the lean angle, reduced to 27°, allows the athlete to keep a perfect trim during both the descent and ascent phases on the cable.

It also offers good performance in terms of dynamics, and in particular for athletes who prefer to use a longer blade in this discipline.

Carbon Blades MANTRA key features:

• 100% IM7 carbon fibre.
• The material used is 100 % Carbon Prepreg produced with hot melt impregnation system, using a micro-toughened tetra-functional epoxy resin.
• 3D-Tech: Proprietary Technology, of CETMA COMPOSITES exclusive know-how, with high pressure, high temperature and high degree of applied vacuum, which lead to a component with 0% void level, without defects, with a uniform matrix/reinforcement ratio across the whole blade.
• FEM Design: MANTRA CWT blades have optimised trough an accurate design by means of Finite Element Softwares (FEM). The Design trough FEM software allows an optimized distribution of the stiffness, with the aim to obtain a deformation ensuring the maximum hydrodynamic efficiency.
• Signature model: developed in collaboration with the world champion CWT bi fins Michele Giurgola.
• Dimensions: Width 195 mm; Length from the bending angle 742 mm; bending angle 27 degrees.
• Available stiffness: soft (S), medium (M).
• Footpocket fitting: CETMA COMPOSITES. Can also be adjusted to be used with other footpockets, such as Mares and Pathos.
  
• Water rail: CETMA COMPOSITES Water rails with variable height and high efficiency.
• Warranty: 2 years on carbon parts; 5 years if fitted with CETMA COMPOSITES footpocket.
• Prizes and awards: Italian Champion 2016 CWT bi-fins -92 meters in 2 minutes and 55 seconds.
