CONCLUSION AND RECOMMENDATIONS 



The major conclusion reached from the rebreather training course on 

 TEKTITE II is that it safely fulfilled its primary purpose to train aqua- 

 nauts in the maintenance and use of a closed circuit diving apparatus. 

 More divers spent more in-water hours on a closed circuit diving unit than 

 ever previously recorded. This feat alone speaks very highly of the train- 

 ing and of the reliability of the Mark X rebreather. Although the units 

 suffered from the problems associated with the introduction of any new gear, 

 the problems that did arise were diagnosed and corrected by the aquanauts. 

 Their training and personal diving capability are what kept malfunctions 

 from becoming serious problems.
