Best Mono Fins 2020

A mono fin is typically used in fin-swimming and free-diving. It consists of a single surface attached to foot pockets for both the free-diver’s feet.

Mono fins can be made of glass fiber or carbon fiber. The diver’s muscle power and swimming style, and the type of activity the mono fin is used for, determine the choice of size, stiffness, and materials.
This type of fin is not used in Scuba Diving.

The arrival of the monofin in the early 1970s led to the breaking of all finswimming world records by the end of the decade due to the improved performance possible when used instead of two ordinary swimfins.

The monofin swimmer extends arms forward, locking hands together, locking the head between the biceps. The undulating movement starts in the shoulders, with maximum amplitude towards the hips; the legs almost don’t bend to transfer the movement to the monofin. This technique is called the dolphin kick.

By slowly oscillating the surface of the monofin when submerged, divers can generate large amounts of thrust even with small or slow movements. This preserves energy which helps when breathholding.

Most monofins consist of a single, wide, glass or carbon fiber reinforced composite blade with graded flexibility, attached to the diver by two rubber foot pockets. The leading edge may be thickened and faired. The blade flexibility is generally controlled by tapering the amount of fibre and thickness of the blade to make the trailing edge thinner and more flexible.

They are often self- and handmade because there are not many choices on the market.

Here are a few recommended mono fins
