Because of the rapid dive, the pressure increases, so the free diver's ear pressure balance rate needs to be faster. Pinching the nose by hand to balance ear pressure can strain muscles, consume extra oxygen, and disrupt body streamlining. Using a nose clip eliminates the need to hold the nose with hands, allowing shoulders to remain relaxed and improving focus during ear pressure balance practice. Therefore, the nose clip is an essential tool for free divers. This nose clip is designed based on Asian nose dimensions and human body statistics, effectively sealing the nostrils without causing discomfort and aiding in ear pressure equalization. It features excellent craftsmanship that ensures no discoloration, no fading, and resistance to seawater corrosion.
