Freediving is a sport where you dive as deep as you can, for as long as you can on one breath. Freedivers push themselves far beyond what is considered normal, diving to depths of over 100 meters, diving along a fine line that could easily spell life or death. This line is what holds the diver in place, preventing them from drifting away, also acting as a form of navigation/orientation. It is also the one piece of equipment that can help pull them back up to surface quickly in an emergency. A freedive line is quite literally a freediver's lifeline, holding them in place between life or death.
