Critics of the buddy system state that the proponents project the image of a "totally reliable buddy" that does not generally exist in reality. Some buddies lack skills or experience and some are unfit, and some personality types are outright dangers; these types have been described as "the untrained diver", "the high-flyer", "the falsely confident diver", "the angry diver", "the buddy from hell" and several others. The bad buddy problem is compounded by training that pressurises the diver to "stick with his buddy" at all times, leading to the situation that the bad buddy sets the criteria of how (badly) the dive is carried out. The solo diver avoids this problem altogether.
