At the surface:
1. Put on and adjust mask, fins, snorkel, BCD, scuba and
weights with assistance.
2. Inflate/deflate a BCD using the low pressure inflator.
Underwater in shallow water:
3. Breathe compressed air by breathing naturally, without
breath-holding.
4. Clear a regulator using both the exhalation and purgebutton
methods, then resume breathing from it.
5. Recover a regulator from behind the shoulder.
6. Clear a partially fl ooded mask.
7. Breathe from an alternate air source supplied by
another diver for at least 30 seconds.
Underwater:
8. Swim with scuba equipment while maintaining control
of both direction and depth. Equalize the ears and
mask to accommodate depth changes.

9. Locate and read the submersible pressure gauge and
signal whether the air supply is adequate or low based
on the gauge’s caution zone.
10. Recognize and demonstrate standard hand signals.
11. Ascend using proper technique.
1. Perform the buddy predive safety check.
2. Demonstrate appropriate deep-water entry.
3. Clear a snorkel using the blast method, then resume
breathing through it without lifting the face from the
water.
4. Exchange snorkel for regulator and regulator for snorkel
repeatedly without lifting the face from the water.
5. Swim at least 50 metres/yards while wearing scuba and
breathing through a snorkel.
6. Adjust for proper weighting — fl oat at eye level at the
surface with no or minimal air in the BCD and while
holding a normal breath.
7. Orally infl ate a BCD to at least half full in water too
deep in which to stand, then fully defl ate it.
8. Remove weights using the quick release mechanism
with minimal assistance
9. Remove weights, scuba unit and fi ns (if necessary) in
water too deep in which to stand and exit using the
most appropriate technique. (Buddy assistance allowed.)
Underwater:
10. Descend using the fi ve-point method.
11. Remove, replace and clear a mask.
12. Breathe without a mask for at least one minute.
13. Disconnect the low pressure hose from the infl ator in
shallow water (either underwater or at the surface.)
14. Respond to air depletion by signaling “out-of-air” in
water too deep in which to stand.
15. Ascend using the five-point method.
