Practicing emergency ascent procedures is a vital training aspect for users of the MK-20 system, as it prepares divers for unexpected situations that could occur while underwater. In the event of an emergency, divers must be equipped with the skills to ascend safely and quickly while minimizing risks such as decompression sickness. This training ensures that divers are familiar with the proper ascent rates and techniques to use when they need to surface quickly due to a variety of potential emergencies, including equipment failure or health issues.

This aspect of training is crucial, as it fosters a deep understanding of safe diving practices and reinforces the importance of preparedness. Divers are also trained to remain calm and follow established protocols to enhance safety in challenging situations. Understanding how to execute emergency ascents correctly is fundamental to a diver's overall safety and competence.
