A: This question gets a huge discussion from a variety of people in the cave diving community. 95% of my students fly into Cancun from all parts of the world. Examples are Finland, Sweden, Belgium, Switzerland, Norway, Korea, Japan, Thailand, United Kingdom, Canada, United States, Germany, Australia, Brazil, Argentina, South Africa, and Israel. Most students prefer all of their training combined as they would rather avoid multiple trips to the Riviera Maya since it can get quite expensive. Some people argue that complete training is too much of an overload at one time. Statistics say not so. Of the 70+ certified cave diver fatalities since 1970, 97% are from the module or multiple-step type of training. I agree. I think that statistic alone shows an obvious message.
One training agency forbids the complete training at one time. The concept has merit as the idea is to gain experience between different levels of training. However, because most cave diving is only available in select regions of the world (Florida, Bahamas, France and the Riviera Maya) and usually offers challenging logistics for access to the dive sites, it’s not like you can jump into your vehicle and go cave diving anytime you wish. For the majority of people, cave diving participation requires extensive planning, financial discipline and available time. Instead of learning only some of the information, why not learn all the information?
From common sense and logical approach, this is what I suggest. If you are not 100% confident about your physical and psychological ability to participate in cave diving training I recommend either gain more open water diving training and experience or take the CAVERN/INTRO TO CAVE DIVING courses. If you are psychologically and physically comfortable with your diving ability and experience level and want to seek the best-disciplined training available, the complete cave diving course training will reward you with far-reaching achievement, satisfaction and success. There is no better joy in teaching than watching students evolve from awkward little ducks and progress each training day into confident and competent cave divers. In addition, gaining experience is always the best teacher!
