Confined Water Dives

which is an open water site that offers swimming-pool-like conditions with

respect to clarity, calmness, and depth. Confined water is a general term that refers to either a pool or confined open water site.

Equipment Assembly and Disassembly:

1. Before the end of Confined Water Dive 3, the student must:

   • Assemble and disassemble a scuba unit at least 3 times

   • Demonstrate proper post-dive care for scuba equipment

2. Before the end of Confined Water Dive 5, the student must assemble and disassemble a scuba unit at least 5 times, with little or no assistance during the last three assemblies/disassemblies.

3. Before the end of Confined Water Dive Three, the student will demonstrate the proper post dive care of scuba equipment (some simulation permitted as described under Recommendations for Training).

4. During all confined water dives, students must have streamlined, secured equipment

Confined Water Dive 1:

By the end of this confined water dive, the student will be able to:

1. Don and adjust mask, fins, snorkel, BCD, scuba and weights with the assistance of a buddy, instructor or certified assistant.

2. Inflate/deflate a BCD at the surface using the low pressure inflator.

3. In shallow water, demonstrate proper compressed-air breathing habits; remembering to breathe naturally and not hold the breath.

4. In shallow water, clear a regulator while underwater using both the exhalation and purge-button methods and resume breathing from it.

5. In shallow water, recover a regulator hose from behind the shoulder while underwater.

6. In shallow water, clear a partially flooded mask while underwater.

7. Swim underwater with scuba equipment while maintaining control of both direction and depth, properly equalizing the ears and mask to accommodate depth changes.

8. While underwater, locate and read the submersible pressure gauge and signal whether the air supply is adequate or low based on the gauge’s caution zone.

9. In shallow water, breathe underwater for at least 30 seconds from an alternate air source supplied by another diver.

10. While underwater, recognize and demonstrate standard hand signals.

11. Demonstrate the techniques for a proper ascent.

12. Student time for fun and skill practice.

13. Exit and debrief.

Confined Water Dive Two:

By the end of this confined water dive, the student will be able to:

1. Perform the predive safety check.

2. Demonstrate appropriate deep-water entry(s).

3. Clear a snorkel of water by using the blast method and resume breathing through it without lifting the face from the water.

4. Exchange snorkel for regulator and regulator for snorkel repeatedly while at the surface without lifting the face from the water.

5. Swim a distance of at least 50 metres/yards at the surface, while wearing scuba and breathing through the snorkel.

6. Demonstrate a descent using the appropriate five step method.

7. Completely remove, replace and clear the mask of water while underwater.

8. Breathe underwater for not less than one minute while not wearing a mask.

9. Demonstrate the response to a leaking low pressure inflator by disconnecting the low pressure hose from the inflator mechanism in shallow water (either underwater or at the surface.)

10. At the surface in water too deep to stand in, orally inflate a BCD to at least 1/2 full and then fully deflate it.

11. Adjust for proper weighting, which is defined as floating at eye level at the surface with an empty BCD and while holding a normal breath.

 Confined Water Dive Three:

By the end of this confined water dive, the student will be able to:

1. Independently establish neutral buoyancy under water by pivoting on the fin tips, or, when appropriate, another point of contact (both oral and low-pressure inflation).

2. Swim at least 10 metres/yards underwater while maintaining neutral buoyancy.

3. Demonstrate the cramp removal technique for self and buddy.

4. At the surface in water too deep to stand up in, perform a tired diver tow for 25 metres/yards.

5. Respond to air depletion by signaling out of air, then securing and breathing from an alternate air source supplied by a buddy for at least one minute while swimming underwater.

6. Share air with another diver using an alternate air source, acting as a donor.  NOTE: Student divers who act as an alternate air source donor in the air depletion exercise or during the Confined Water

7. Dive One alternate air source breathing skill have completed this requirement.

8. Breathe effectively from a free-flowing regulator for not less than 30 seconds.

9. Simulate a controlled emergency swimming ascent by swimming horizontally underwater for at least 9 metres/30 feet while continuously exhaling by emitting a continuous aaahhh sound.

10. Time for fun and skills practice.

Confined Water Dive Four:

By the end of this confined water dive, the student will be able to:

1. Swim underwater without a mask for a distance of not less than 15 metres/50 feet, and replace and clear the mask underwater.

2. Using buoyancy control only, hover without kicking or sculling for at least 30 seconds.

3. Optional Skill:  Buddy breathe sharing a single air source for a distance of at least 15 metres/50 feet under water both as a donor and a receiver.

4. Time for fun and practice.

Confined Water Dive Five:

By the end of this confined water dive, the student will be able to:

1. Remove, replace, adjust and secure the scuba unit and weights at the surface, with minimal assistance, in water to deep to stand up in.

2. Remove, replace, adjust and secure the weight belt on the bottom in water too deep to stand up in, or for students using integrated BCDs or weight harness systems, in shallow water, remove weights while underwater.

3. Remove, replace, adjust and secure the scuba unit on the bottom, with minimal assistance, in water too deep to stand up in.

4. Time for fun and practice.
