The Mares Avanti Quattro + diving fins are the perfect choice for divers of all levels, from beginners to experienced professionals.
Here’s a breakdown of the features that make this fin one of the best-selling in the world.
Fin Design: The Mares Avanti Quattro + diving fins boast a sleek and functional open-heel design. The four-channel blade system, a trademark feature of Mares fins, is incredibly effective in channeling water efficiently with each kick. This design not only maximizes propulsion but also minimizes leg fatigue, allowing for longer and more comfortable dives. The foot pockets include perforations that prevent a “parachute effect”, a type of drag that is sometimes reported by divers.
Materials: The foot pocket of this fin is made from Thermoplastic Rubber, a material that has characteristics of both rubber and plastic. This offers protection and comfort. The blade is made from Tecralene, a high-performance technopolymer. Tecralene is flexible and durable, allowing the blades to arch during a fin stroke.
Maintenance: Keeping these diving fins in good working condition is easy – simply rinse them with clean fresh water after every use and dry them in a shaded area. Store fins in a cool, dry space.
