How many dives in a day is usually allowed or a safe practise? I heard that CMAS only allows 2 dives a day, but I am doing 2-3 dives a day. I have done 4 dives on one occasion. I have never felt any problem so far, but I would like to know if 3-4 dives a day is safe practise. I usually dive almost every weekend and plan my dive from deep to shallow (about 35m to 40m -> 20m, or 30 -> 15m thoughout the day). I put at least an hour break in between dives. Is this safe?
