The rope has a direct impact on your safety in freediving. It helps with technique tuning and posture adjustments during training, too. Finding a good rope is not easy.
A stretchable rope is not suitable for freediving training. It can stretch or shrink, depending on many factors including aging and variations of the bottom weight. Such a rope can be dangerous. The reason is simple: it would be impossible to know its “real” length with precision (diving depth limit is set by the length of the rope).
STATIC (not dynamic) climbing ropes are an acceptable option for freedivers. But they do elongate,too. A static climbing rope elongation is generally less than 2%. This is not a problem if you are shallow, but for dives deeper than 40m it can be dangerous. Even with 2% elongation the rope will absorb your efforts while pulling yourself up (FIM freedives). Thus a freedive would take more effort and more oxygen, which is not good nor safe. In addition, please imagine a freediver aiming for 100m, finding himself accidentally 2m deeper! It’s two meters deeper than 100m.
A 12mm rope is a good choice because it is comfortable to grasp for pulling up. Last but not least, it should be sinking and not floating on the surface!
