                          SKILLS TO BE CHECKED IN THE THIRD OPEN WATER DIVE
In this third dive students should be tested in more demanding skills. Some exercises are repeated from
previous dives for continuous evaluation. The depth of this dive should not exceed 18 meters (60 feet).
Suggested bottom time: 20 minutes (15 minutes in cold water).

2. putting the equipment on and taking it off

3. (*) underwater (pivotal method) buoyancy control

4. swim underwater (finning methods: Frog and Dolphin)

5. (*) proper descent and ascent procedures (e.g. equalizing pressure in ears and mask, rotating during ascent,
hand up, Ok sign, etc)
6. (*) mouthpiece clearing - regulator (Purge method)

7. (*) mask clearing, including removal and replacement. Please note: Special safety precautions are to be taken
during the removal and replacement of mask in open water, specifically in those areas with cold water.
8. (*) underwater regulator recovery (two methods: back reach and side reach)

9. (*) descending and ascending with a buoyancy compensator and safety stop

10. basic instrument monitoring (often)

11. equipment care and dive log, including tables calculations


                         SKILLS TO BE CHECKED IN THE FOURTH OPEN WATER DIVE
This fourth dive should be a relaxed, end of the course dive, with minimal skill testing. Some exercises are
repeated from previous dives for continuous evaluation. The depth of this dive should not exceed 25 me-
ters / 80 feet (only if conditions allow it). Suggested bottom time: 15 minutes.
1. (*) air consumption consideration and dive planning for this type of dive (25 meters/80 feet)

2. buddy system (above and below the water)

3. diving equipment assembly and disassembly (at water's edge)

4. putting the equipment on and taking it off

5. (*) proper descent and ascent procedures (e.g. equalizing pressure in ears and mask, rotating during ascent,
hand up, Ok sign, etc) and safety stop
6. (*) underwater (pivotal method) buoyancy control

7. (*) mouthpiece clearing - regulator (Purge method)

8. more often than usual basic instrument monitoring (own and buddy’s)

9. equipment care and dive log, including tables calculations




Instructors can do more skill testing dives if they wish, however, the above four dives must be done and the skills
defined in those dives must be tested, following the skill increase difficulty process outlined
