In due time, an amateur scuba diver would gain the necessary experience from a lot of his diving trips. Plus, the proper scuba diving training programs provided by various groups and institutions would definitely come in handy. This would allow the
scuba diver to gain intermediary to advanced scuba diving skills. Thus, with the proper training and the proper equipment, a good scuba diver could go to depths deeper than just 18 feet. Now this would be the fun part of a scuba diving trip, wouldn't it? I guess it would be something to look forward to for those amateur divers out there.
