Wet suits are far better than an actual semi-dry one in an amateur scuba diver's, or a seasoned scuba diver's, diving expeditions. This is because, for an amateur scuba diver, getting another suit, if he manages to become well accustomed to diving, would generally be more expensive. That is, than settling for a good wet suit. As for seasoned scuba divers, these guys dive in depths deeper than 200 feet. Thus, it would be suicide not to use one, you know. So if you're either a newbie or a professional, when it comes to actual scuba diving, you should use a good wet suit over an actual semi-dry one.
