The only difference between success and failure is in the training and discipline of the individual diver. CCRs are not for the average recreational diver. These units are complex machines requiring extensive routine maintenance. Training on the MK15, for example, generally runs about 7-10 days of intensive classroom, practical, and in-water drills. Every possible failure-mode should be practiced by the student-diver. Currently, courses are offered by IANTD and TDI. Once initial training is accomplished, the new rebreather diver should attain at least 100 hours of dives no deeper than 60-100 fsw on the unit before attempting to go deeper. Since the introduction of the Dräger Dolphin and Ray rebreathers, recreational divers can enjoy the benefits of diving an RB unit that requires very little tr
