Float around on your backs,keep the heads up,no bending over backwards and breathing in...!
Add the weight belts..
This is were...if that was me under the water...this whole expedition would blow up...I get claustrophobic...standing on me and keeping me under would not go down well at all!!!
Now you get the big guns out...
Oh my word,do you really expect us to go under the water wearing these heavies....!
You have to spit in those masks to be able to see clearly....
And lads and lass,you are hereby pronounced, ready to go diving in the Ocean!
