By using a kicking motion with your legs, the fins help in propelling you forward and moving you through the water with greater ease and speed.

### What does dcs stand for:

Decompression Sickness
Explanation
DCS stands for Decompression Sickness, which is a condition that occurs when a person experiences rapid changes in pressure, typically when diving or ascending to high altitudes. This condition is caused by the formation of nitrogen bubbles in the body tissues and bloodstream due to the rapid decrease in pressure. Symptoms of decompression sickness can range from mild joint pain and fatigue to more severe symptoms such as difficulty breathing, chest pain, and neurological issues. Prompt medical attention and proper decompression procedures are crucial in managing and treating decompression sickness.

This is crucial for effectively filtering out airborne particles and protecting the wearer from respiratory hazards. A mask that doesn't fit well may not provide adequate protection and can compromise its effectiveness. Therefore, regardless of the color, style, or cost, the fit should be the top priority when choosing a mask.
