Dynamic Apnea Bi Fins

This involves finning up and down a swimming pool (or in the sea), to cover a horizontal distance, using two fins – use of monofin is prohibited. Physically, it is very demanding. This can either be done in a 25m pool or in a 50m pool. Using a 50m pool is better for this category since fewer turns are necessary which tend to break the rhythm.

In short: swimming as far as possible underwater using two fins
