LIGHTJET fins with negative springs

Tecline LightJet Fins - Negative Buoyancy with Stainless Steel Springs

The Tecline LightJet fins represent the evolution of technical thrust fins. They combine the traditional "Jet Stream" design with modern high-performance materials, offering millimeter-precise control of movement. This specific version is designed with negative buoyancy, a fundamental feature for those looking to stabilize their trim, especially when using drysuits.

Main Features:

• Negative Buoyancy: Designed to sink slightly, these fins help balance the positive leg buoyancy typical of drysuits. They are the ideal solution for divers struggling with "light feet," eliminating the need for ankle weights.
• High-Tech TPE Material: Made from an extremely durable vulcanized thermoplastic technopolymer. This material ensures a constant elastic response in both icy and tropical waters, maintaining shape and power over time.
• Stainless Steel Spring Straps: Equipped as standard with stainless steel springs and an ergonomic pull tab. They guarantee an immediate fit, constant tension on the heel, and virtually unlimited durability.
• Optimized Propulsion: Hydrodynamic vents reduce effort during the recovery phase and maximize thrust during frog kicks or flutter kicks, offering precision even in backward movements (Back Kick).

Size Guide and Applications:

• S/M: Recommended for those with small feet or using thin wetsuit boots.
• L: The most common size, perfect for those wearing standard drysuit boots (sizes 41-44).
• XL: Designed to accommodate bulky Rock Boots or rigid cold-water boots, thanks to the 11 cm wide foot pocket.

Why choose LightJet Negative?

Unlike classic rubber Jet fins, which can be excessively heavy and tiring, LightJet Negative offer the perfect weight for impeccable horizontal trim without sacrificing agility. They are modern technical fins: short for maneuvering in wrecks or caves, powerful for combating current, and built to last a lifetime.
