As New - Never used in the water - Very minor signs of being moved around
Information:
The Cetma Composites Lotus HD (Hard) represents a major evolution in high-performance polymer diving fins, engineered specifically for demanding freedivers, spearfishers, and winter anglers who require explosive propulsion. Developed using Cetma Composites' advanced aerospace and automotive material design expertise, these fins feature an internally developed, specialized micro-composite polymer blend that provides unmatched stiffness distribution, reactivity, and long-term durability.
Compared to the smoother, more progressive standard Lotus LT model, the Lotus HD is roughly 30% stiffer. This design delivers a highly immediate snap and substantial bottom-heavy thrust, making it exceptional for deep ascents, navigating strong currents, or pushing off the bottom with heavy winter weights (12–13+ kg).
Key Features & Technical Specifications
• Advanced Material: Built from an internally engineered polymer micro-composite that mimics carbon-fibre finning techniques at a fraction of the cost.
• Dynamic Power Control (DPC): The optimized flex profile creates a perfect parabolic curve when under load, storing energy during the power stroke and launching it forward at the end of each kick.
• Ergonomic 30° Blade Angle: Aligns the blade naturally with the leg extension to significantly decrease ankle fatigue during intensive surface swimming or deep ascents.
• Variable Hydrodynamic Water Rails: Progressive, variable-height side rails eliminate wobble and prevent water from spilling laterally over the blade, translating lateral movement into clean, forward thrust.
• S-Wing Foot Pockets: Features the innovative Cetma Composites S-Wing Pockets that anchor power transfer straight from the heel, securing a comfortable fit without localized pressure points.
• Modular Compatibility: The modular, screw-attached design allows you to seamlessly upgrade to carbon fiber blades in the future without needing to buy a new pair of foot pockets.
