Certified fins obligatory for: • The participation in CMAS championships, World Cup and in international competitions. • Certification for any records with Monofins On each Monofin, the sticker provided by CMAS to the manufacturers must be stuck on the blade before to sell, thus certifying the homologation of the Monofin. Manufacturers make sure the sticker is properly glued to the top of the blade and use a glue that allows the sticker not to peel off over time and use the material.
2.5.2. Equipment allowed in pools and in open water for Bi-Fins (BF) events:
