Introduction.

One of the skill building exercises of the PADI Divemaster education is called "Equipment Exchange":

In confined water, demonstrate the ability to effectively respond to unusual circumstances underwater by exchanging all scuba equipment (except exposure suits and weights) with a buddy while sharing a single regulator second stage earning af minimum score of 3* 

Conduct:

• Orient candidates to procedures for sharing a single regulator second stage, including exhalation between breaths and not covering the purge button as the regulator is passed back and forth.
• Give buddy teams less than five minutes to discuss the exercise
• Have candidates begin sharing a single regulator stage in water too deep in which to stand, exchange equipment and continue sharing air until they reach shallow water.
• Do not assign problems - allow candidates to resolve any naturally occuring onees.

 *) Scoring criteria not covered here. We probably scored 4 - 5. Better than minimum.
