| Water Skills Development |
|
1. A confined water session must be completed before conducting any OW dives.
2. Swim with full underwater equipment required in Program for at least 5 minutes.
3. Swim in a simulated out-of-air situation (without breathing, and exhaling slowly) for a distance of at least 60 feet (18 meters) with full gear, then commence breathing. Repeat previous drill with 2 divers swimming side-by-side, but have one diver hand-off the long-hose second-stage regulator to the other diver and commence gas sharing. After remaining at rest for 3 breaths, continue swimming at an average pace for at least 10 minutes.
4. Remove and replace equipment during confined water training (doubles and stage[s]), first on the surface, then on the bottom, in less than 2 minutes.
5. Remove the harness and cylinders from a simulated unconscious diver in less than 1 ½ minutes. (Students who exceed the time limit on this skill must have a quick-release added to their harness).
6. Divers using a quick-release on their harness or backpack must, in confined water, swim the system while the instructor disconnects the quick-release to simulate a failure. The student is to swim the system demonstrating control of buoyancy and body positioning with the quick disconnected for sufficient duration to satisfy the instructor that the student is capable of managing.
7. Demonstrate an ability to respond to a single-bladder BCD failure by the two methods listed below. (Students using gear configurations that prevent accomplishment of these two skills will be required to wear a redundant BCD. Students who already have a redundant BCD or dry suit may use one of these alternates after attempting perform the methods without the use of the alternative.)
a. Completely deflate BCD and swim while maintaining buoyancy control for at least two minutes.
b. Completely deflate BCD, ascend safely to the surface, and remain afloat for at least 3 minutes.
NOTE: If at any time the student starts to over-exert, or if it is obvious that the skill cannot be accomplished, the instructor is to ensure that the BCD is inflated.
8. In confined water, have a student lose buoyancy by deflation of the BCD and then attempt to utilize a lift bag or other secondary buoyant device as a BCD.
NOTE: This skill is to demonstrate how effective these devices are and to reinforce that even if not suitable for a redundant BCD they still provide an option for self rescue in an emergency situation.
9. Two divers approximately 60 feet (18 meters) apart, with blacked-out masks or eyes closed, and while simulating an out of air situation (without breathing, and exhaling slowly), locate each other (using side of pool, rail on wreck, guide line, etc. for orientation) and begin gas sharing via long hose. After taking 3 breaths at rest, continue swimming while sharing gas for at least 3 minutes. This drill may be accomplished by having one student swim 30 feet (9 meters) to donor, and repeat for other diver.
10. While two divers are swimming side-by-side, the Instructor signals one to remain stationary while the other continues swimming for at least 3 more kicks. The stationary diver then simulates an out-of gas situation by swimming (without breathing, and exhaling slowly) to the other diver and commences gas sharing for at least 2 minutes. The instructor may substitute this skill by starting the drill at some time when the students are apart from each other by a comparable distance as would be achieved by 3 kicks.
11. Simulate gas failure with valve shutdowns for both primary and secondary regulators. The entire drill must be completed in less than 1 minute.
12. Close eyes, remove and replace stage cylinder, make regulator switch to stage cylinder, then switch back to primary gas supply.
13. Perform gas shutdown at least once per dive. (It is not necessary to remove mouthpiece.)
14. Remove and replace stage cylinder on all dives with as little buoyancy change as possible.
15. Demonstrate use of a safety reel and deploy a lift bag while maintaining a stable depth.
16. Demonstrate good dive technique and swimming (SCUBA) abilities combined with correct buoyancy control.
17. Determine RMV and demonstrate ability to calculate and perform gas matching. |

4. Deploy lift bag in less than 1½ minutes, and repeat at least 5 times during the Program.
5. Swim a distance of at least 75 feet (23 meters) without wearing a mask.
6. Practice removing and replacing a stage cylinder. Must be completed at rest and while swimming.
7. Have 2 divers swim side-by-side, in full equipment, simulating an out-of-gas situation (without breathing, and exhaling slowly), for a distance of 60 feet (18 meters), then stop and begin breathing with one diver handing-off the long second stage hose to the other diver. Divers should remain a rest for 3 breaths, and then swim at an average pace for at least 10 minutes. On Rebreathers this drill should be done with the diver breathing from the stage cylinder.
8. Remove the harness and cylinders from a simulated unconscious diver in less than 1½ minutes. (Students who exceed the time limit on this skill must have a quick-release added to their harness).
9. Divers using a quick-release on their harness or backpack must, in confined water, swim the system while the instructor disconnects the quick-release to simulate a failure. The student is to swim the system demonstrating control of buoyancy and body positioning with the quick disconnect released for sufficient duration to satisfy the instructor that this type failure may be managed by the student.
10. Demonstrate an ability to respond to a single-bladder BCD failure by the two methods listed below. (Students using gear configurations that prevent accomplishment of these two skills will be required to wear a redundant BCD. Students who already have a redundant BCD or dry suit may use one of these alternates after attempting perform the methods without the use of the alternative.)
a. Completely deflate BCD and swim while maintaining buoyancy control for at least two minutes.
b. Completely deflate BCD, ascend safely to the surface, and remain afloat for at least 3 minutes.
NOTE: If at any time the student starts to over-exert, or if it is obvious that the skill cannot be accomplished, the instructor is to ensure that the BCD is inflated.
11. In confined water, have a student lose buoyancy by deflation of the BCD and then attempt to utilize a lift bag or other secondary buoyant device as a BCD.
NOTE: This skill is to demonstrate how effective these devices are and to reinforce that even if not suitable for a redundant BCD they still provide an option for self rescue in an emergency situation.
12. Following a means of reference (pool wall, guide line, ship railing, etc.) with eyes closed, remove stage cylinder and swim a distance of at least 15 feet (4.5 meters). Reverse direction, return to stage cylinder and replace it on correct side.
13. Two divers approximately 60 feet (18 meters) apart, with blacked-out masks or eyes closed, and while simulating an out of air situation, locate each other (using side of pool, rail on wreck, guide line, etc. for orientation) and begin gas sharing via long hose.
14. Prior to dives, students must use IANTD Gas Management Charts to match gas turn points.
15. Open and close tank valves at least once on all dives.
16. At least once on each dive, Instructor is to signal to student(s) that one of their regulators is malfunctioning and the student is to take the corrective action (Open Circuit only).
17. Perform gas sharing in one form or another on at least 3 of the air dives. It is recommended that the Instructor do this at times when it surprises at least one of the divers, and at a point when there is a reasonable distance between the divers. Determine RMV and demonstrate ability to calculate and perform gas matching. (Open Circuit only) |

1. This Program is designed for those individuals already involved in deep diving activities, but is not intended to be used as an enticement to divers who are content to remain in Sport or EANx diving limits.
2. Trimix affords a safer means for deep-water exploration for divers who dive deep or perform with a clear head at depth. The IANTD Trimix Diver Program requires the diver to be self-sufficient/reliant.
3. The knowledge and skills taught in this program are more than adequate to qualify divers to perform Trimix Dives outside of training up to 333 fsw (100 msw). |
|
Prerequisties
|
|
1. Must be qualified as an IANTD Technical Diver or Technical Cave Diver or Technical Wreck Diver or Normoxic Trimix Diver or equivalent.
2. Must provide proof of a minimum of 200 logged dives, of which at least 25 were to depths between 140 fsw (42 msw) and 200 fsw (60 msw) or sufficient experience doing technical dives to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.
3. Must be a minimum of 18 years of age. |
| Program Content |
|
1. All lectures completed with IANTD Course-specific Slides pertaining to the theory in the IANTD Trimix Diver Student Kit.
2. Perform two skills-training dives following completion of the confined water session(s) add in and a total of 4 dives will be conducted in this course with a minimum in which two stage cylinders are used, to a depth between 60 fsw (18 msw) and 200 fsw (60 msw). These dives may be on air, EANx or Trimix provided the depths are acceptable for the gas used, and two gas switches are practiced during ascent. Divers may not do dives on air deeper than 130 fsw (39 msw).
3. All depths must be worked up to incrementally with no increase greater than 40 fsw (12 msw) from one dive to the next (the first dive in the course on mix must not be more than 33 fsw (10 msw) deeper than the student’s previous experience in deep diving). One dive must be to at least 200 fsw (60 msw) or deeper, and the deepest training depth may not exceed 333 fsw (100 msw).
4. All dives must include two gas switches.
5. Divers entering the Program on equivalent experience must complete the above requirements plus make two additional training (for a total of six training dives) dives using two stage cylinders. These two additional dives may be on air, EANx or Trimix at the instructor’s discretion.
6. If the course is a combined course (e.g., Technical Diver and Trimix Diver), the Program must include a minimum of 420 minutes of open-water run time completed within at least 7 dives.
7. To complete the course within the minimum specified dives. With 2 or more additional dives the student may graduate from the course with an overall average score of 6 points. |

| Water Skills Development |
|
1. A confined water session must be completed before conducting any OW dives.
2. Two divers approximately 60 feet (18 meters) apart, locate each other while simulating an out of air situation (without breathing, and exhaling slowly) and begin gas sharing via long hose. After taking 3 breaths at rest, continue swimming at a normal rate while sharing gas for at least 2 minutes.
3. Simulate gas failure with valve shutdowns for both primary and secondary regulators. The entire drill must be completed in less than 1 minute. This drill should be completed at least once each dive, with a buddy acting as a safety diver, then switch roles. Upon completion of skill, verify both primary tanks are turned back on.
4. While swimming, demonstrate efficient switch to stage cylinder regulators.
5. Following a means of reference (pool wall, guide line, ship railing, etc.) with eyes closed, remove stage cylinders and swim a distance of at least 15 feet (4.6 meters). Reverse direction, return to stage cylinders and replace them on correct sides, identifying each cylinder by feel.
6. Prior to dives, students must use IANTD Gas Management Charts to match gas turn points.
7. Remove and replace stage cylinders both at rest and while swimming.
8. Deploy and use a lift bag or up line at least once in OW.
9. Remove and replace equipment during confined water training (doubles and stage[s]), first on the surface, then on the bottom, in less than 2 minutes.
10. Simulate the rescue of a diver. Tow the diver on the surface for a distance of at least 40 feet (12 meters) while simulating mouth-to-mouth resuscitation. Go through EMS procedures and remove equipment from victim in the water (equipment removal must be accomplished in less than 1.5 minutes, students in continuous webbing who cannot have their equipment removed within the time limit must add a quick release to their harness). Repeat until proficient. |
