Hello all,
I am new in this and I am reading though the PADI Open Water Diver manual to get certified.
But, i am kind of lost in "how to calculate the different scenarios of reserve, safety stop and turn around point" Need some guidance.
I have this question:
My buddy and I are planning a shore dive. We're descending onto a very gradual slope that begins at 5 meters/15 feet, so our descent and ascent will be gradual part of swimming out and back underwater. We have similar cylinders filled up to 200 bar/3000 psi. We plan:
*50 bar/ 500 psi reserve
*20 bar/300 psi for our safety stop
*To turn the dive when we've used one-third of the air available to use on the dive.
This means we should head back when either of our SPGs read
a. 70 bar/800 psi
b. 145 bar/1900 psi
c. 157 bar/2270 psi
d. 170 bar/2500 psi
Thanks for your help,
G
