Today I heard an interesting thing from a very experienced diver:
When you put air into your BC and you are at 40m you start to sink because of negative bubbles. If you are a lot below 40m, adding air in your BC does nothing, hence there is no fast ascend like that from beyond 40m.
Is this the case? wth are "negative bubbles"?
