Mantis Fin is designed to provide a smooth and powerful kick. Its wide entrance and narrow exit jet holes stabilize the fin reducing turbulence
and side planing for a steady kick
every time. Great for skin and
scuba diving.

  • Flexible Foot Pocket Easy to put on and take off
    Close Flexible Foot Pocket The foot pocket is constructed using a more pliant rubber material allowing for more flexibility. This makes it easier to put on and take off the fin, even for first time users.

  • Smooth Water Flow Blade Tip Allows water to escape smoothly
    Smooth Water Flow Blade Tip The V-shaped tip of the blade allow water to smoothly flow away from the fin as you kick. This allows the blade to rebound more quickly ultimately allowing you to kick more efficiently without tiring out during your session.

  • Hybrid Rubber Greater Propulsion
    Hybrid Rubber Gull’s innovative production methods integrate varying stiffness levels of rubber for the foot pocket, ribs, and blades of a fin. Each engineered carefully for powerful and smooth propulsion.

  • Raised Ribs Stronger down kicks
    Raised Ribs The raised blade ribs eliminate side planing and blade twist, which would otherwise occur with long fins. Fin work is smooth. The ribs maximize rubber rebound to enable you to enjoy confident, powerful propulsion.

DX Spec Fin Buckle

The buckle is now easier to deal with. With a better-designed center guide, the quick-release locking mechanism can be latched and detached even by weak and tired hands. Less force is also required with the improved strap adjustment button. As required, you can easily fine tune the strap fitting.

Jet Holes (Two Locations)

Jet holes funnel water rearwards, reducing turbulence and side planing when you kick. To achieve a powerful jet flow, these new-design jet holes have wide entrances and narrow exits.
