Once you come back from the dive and your tank is back in place, loosen the first stage so they can fill the tank right in front of you. Tidy up your belongings and hang up your suit with the zipper closed. Taking care of your diving equipment is your responsibility at all times. So if something breaks or you lose something, that is not only a shame, but that is also for your account. As a rule, you do not rinse your equipment after every dive, but only at the end of the trip. This prevents unnecessary water consumption.
