Although it shouldn't have happened, on a dive I fail to watch my SPG and run out of air. If my buddy is close by, my best option is to __________. Another option is to _____________, if I'm in shallow water and the surface is closer than my buddy.
NB: The options still remain as written in the question
Answer:
a) ascend using my buddy's alternate air source / make a controlled emergency swimming ascent
Explanation:
Since I have exhausted my own air source, my buddy's alternate air source will be the only saver if he is close by. Controlled emergency swimming accent is used if the swimmer's buddy is far but the swimmer is close to the surface. Buoyant emergency ascent can only be used if the swimmer is deep away from the surface and needs to make it to the surface.
B ) Ascend using my buddy alternative air source / make an emergency Ascent
Explanation:
From the description it can be seen his buddy is close by of which he can easily use the alternative air source. Also we can see that he is closer to the water surface than his buddy, of which controlled emergency swimming ascent is highly favourable in this condition.
