Carbon Fiber Blades MANTRA key features:

1) 100% IM7 carbon fibre.
2) The material used is 100 % Carbon Prepreg produced with hot melt impregnation system, using a micro-toughened tetra-functional epoxy resin.
3) 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.
4) FEM Design: MANTRA blades are optimized 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.
5) Signature model: developed in collaboration with the world champion CWT bi fins Michele Giurgola.
6) DRS (Dynamic Resonance System) innovative and exclusive CETMA COMPOSITES system. DRS implies that MANTRA blades were designed to reach in resonance in a definite frequency of kick. Resonance phenomenon is well note physical phenomenon characterizing all the structures. Simplifying, when a structure is forced with a frequency close to its natural frequency the amplitude of vibration increase in a very efficiency way (low damping). Operating by distribution of the stiffness along the blade we “tuned” the blades to certain natural frequencies. So when the blade is driven, by kicking, with a certain frequencies range the user feeling is a very low effort with an outrageous thrust. This study is done using a laser vibrometer (LDV) to perform a modal analysis, which helps in a stiffness distribution design of the blade.
7) Dimensions: Width 195 mm; Length from the bending angle 742 mm; bending angle 33 degrees.
8) Available stiffness: super soft (XS), soft (S), medium (M).
9) Colour choice: White, Gold, Magenta.
10) Footpocket fitting: CETMA COMPOSITES, Mares and Pathos.
11) Water rail: CETMA COMPOSITES Water rails with variable height and high efficiency.
12) Warranty: 2 years on carbon parts; 5 years if fitted with CETMA COMPOSITES footpocket ( Find out more ).
13) Prizes and awards: Italian Champion 2016 CWT bi-fins -92 meters in 2 minutes and 55 seconds.

    Buonasera io sarei interessato alle vostre pale pero' vorrei ulteriori consigli da voi . io pesco tra i 15 ed i 20 metri di profondità' quale pala secondo voi e' la più adatta per me sono una persona alta 1, 68 e 65 di peso . Grazie della vs. cordiale attenzione . Roberto Giare' Answer:
    Salve, nel suo caso potrebbe optare per una prana soft (pala corta è più economica). Chiaramente in un'ottica di miglioramento futuro delle prestazioni, potrebbe optare per delle mantra soft

    G'day, I'm interested in getting a pair of your fins, the Mantra i think or the Edge, I've tried the old model of the Edge and I really like them. To give you an idea of my activities, I'm a freediving instructor, doing occasionally Spearfishing, and i'm soon gonna be working with an NGO doing Coral Rehabilitation, I'm 1,75cm and weight around 67kg. I'm hesitating if I choose Mantra which stifness I should take? Now the for the Foot pocket my size is 42 and i'm wondering if I should take 40-42 or 42-44, considering I want a Pathos pocket. And last question, I'm going soon to Asia, by the end of November or early December, should I get the delivery here in France or directly to Asia? It all depends on how long you take to deliver them I guess Thank you for your time, and have a great day ahead Nicolas Answer:
    Hi, we strongly recommend mantra soft, it is more suitable for your need. Regarding pathos number, I think 42-44 should be ok. Regards

    Buongiorno sono interessato alla pala mantra che dovrà essere utilizzata sia in piscina per gli allenamenti di dinamica in piscina, sia per la pesca in apnea; avrei un unico dubbio dettato dalla rigidezza della pala; il peso potrebbe variare tra gli 80 kg e gli 85 kg, ma in generale non dovrebbe ne diminuire ne aumentare oltre i due valori; a tal proposito, vorrei chiedervi, quale rigidità consigliereste? non vorrei che la S risulti troppo morbida e viceversa che la M risulti troppo rigida, annullando quelli che possono essere gli effetti della pala, se scelta accuratamente. Stando alla tabella da voi indicata opterei per l'acquisto di una mantra con rigidità M, ma ho voluto chiedere un vostro parere prima dell'acquisto. Vi ringrazio. Cordialmente. Andrea Answer:
    Salve, le suggeriamo di scegliere la mantra medium. Comunque non è una pinna rigida, e quindi andrà sicuramente bene. Saluti
