When a student chooses to do a freediving course,  while their primary objective in most cases, is to become a safe freediver, they will also be expected to learn how to be a safe freediving buddy too. Any responsible freediver will ensure they have a qualified freeediving buddy with them at all times - one who is trained and able to rescue them from any scenario they might find themselves in, while extending the same level of safety and reassurance in return to their freediving buddy.
