Deep Diver

1. This Program is designed to provide responsible training to divers who plan to dive to a maximum of 130 fsw (39 msw) on air.
2. The IANTD Deep Diver Program trains divers in skills, performance, theory and planning of deep dives. This Program remains within the commonly practiced depth of 130 fsw (39 msw), and is the first sanctioned international Program to provide proper training in safe deep diving skills and performance.
3. It is recommended that this Program be taught in conjunction with the IANTD EANx Diver Program.

Prerequisites

1. Must be qualified as an IANTD Advanced Open Water Diver or equivalent.
2. Must provide proof of a minimum of 10 logged dives.
3. Must be a minimum of 15 years of age with a parent or guardian authorization, or a minimum of 12 years of age for Junior Diver qualification, or a minimum of 18 years of age without guardian approval.

Texts

1. IANTD Deep Diver Student Manual & Workbook, or equivalent text(s) approved in writing by the Board of Directors (written approval will be issued by IAND, Inc./IANTD World Headquarters).

Program Content

1. All lecture and theory material must be completed.
2. This Program must include a minimum of 100 minutes of OW bottom time completed within 4 to 6 dives, 2 of which must be to depths between 100 fsw (30 msw) and 130 fsw (39 msw). If combined with an EANx Program, the dives in both Programs may be included within the minimum 100 minutes of bottom time.

Equipment Requirements

1. Same as Equipment requirements listed in the general Sport Diver Programs overview.

Program Limits

1. There may be no more than 4 students per Instructor. This ratio may be increased by 2 students for each assisting IANTD Divemaster, up to a maximum of 8 students with 2 IANTD Divemasters per class session.
2. No dives may be conducted to depths greater than 130 fsw (39 msw).
3. Appropriate safety decompression stops must be performed.

Waterskills Development

1. A confined water session must be completed before conducting any OW dives.
2. Swim in full underwater equipment for 5 minutes.
3. Calculate RMV from gas consumed during a 10-minute swim (based on change in cylinder pressure).
4. Become proficient in the following propulsion techniques: modified flutter, modified frog, modified dolphin and standard shuffle kicks.
5. Demonstrate buoyancy control by:
   1. A timed ascent at a rate of 20 feet (6 meters) per minute.
   2. Hover at constant depth for 3 minutes.
   3. Swim 75 feet (23 meters) in full equipment without mask.
   4. Deploy a lift bag in less than 2 minutes.
   5. Air sharing skills or appropriate rebreather gas management drill for 0ut-of-air diver
6. If a rebreather is used by the student, the appropriate rebreather drills must be incorporated.
   1. Swim in a simulated out-of-air situation (without breathing, and exhaling slowly) for a distance of at least 45 feet (15 meters), and commence gas sharing. While gas sharing, continue to swim for at least 4 minutes while maintaining a normal swim rate; or appropriate rebreather gas management drill for out-of air diver.
   2. Repeat the above step with the gas-recipient diver wearing a fully-flooded mask (or no mask at all), and swim 2 minutes while sharing gas; or appropriate rebreather gas management drill for out-of air diver.

   NOTE: All gas sharing drills are via the alternate second stage and not manual air sharing from the same second stage.

7. Perform valve shutdowns: change regulators and shut the primary-regulator valve off, then reopen valve and repeat as if the secondary (backup) regulator had malfunctioned. Repeat until skill (both valve openings shutdowns) is completed in less than 2 minutes.
8. Close and open tank valves on all dives.
9. Deploy lift bag on at least 2 occasions.
10. Remove and replace tank and BCD at surface on at least one dive.
11. All ascents are to be at a rate of 30 feet (9 meters) per minute or slower
