Advance Nitrox or Deep Diver

[Andy_W]

Hi Guys

Please help me to think and decide of these;

should I go for IANTD deep diver course or advance nitrox or both.
(I'm a normal rec diver and it's never cross my mind to be a tech diver one day)

What you will learn in that course? how usefull is it for rec diver like me. :huh:

thanks a lot

Andy

Advantages , if you can that combine both courses in the same time, IANTD deep diver carry twin tanks different with NAUI, PADI or other agency, you will learn more technically skills.

Good luck mate.

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. No dives having a mandatory decompression Stop exceeding 3 minutes may be made, unless the course is combined with
Advanced EANx or Advanced Recreational Trimix.
G. Water Skills 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:
a. A timed ascent at a rate of 20 feet (6 meters) per minute.
b. Hover at constant depth for 3 minutes.
c. Swim 75 feet (23 meters) in full equipment without mask.
d. Deploy a lift bag in less than 2 minutes.
e. 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.
a. 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.
b. 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.

Go deep. It'll offer you more experience outside your comfort zone so you'll be a more proficient diver.

Advanced EANx Diver

A. Purpose
1. This Program is designed to extend the diver’s knowledge in the use of EANx for Sport diving. It further develops diving skills
and provides a greater understanding of the EANx concept of diving.
2. The Program employs EANx mixes up to 1.5 PO2.
3. This program qualifies divers to do dive to 140 fsw (42 msw) and do decompression stops required dives up to 15 minutes.


B. Prerequisites
1. Must be qualified as an IANTD EANx Diver and IANTD Deep Diver with proof of a minimum of 30 logged dives or sufficient
experience to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.
2. Must be a minimum of 15 years of age with a parent or guardian authorization, or a minimum of 18 years of age without
guardian approval.

C. Program Content
1. All lectures completed with IANTD Course-specific Slides pertaining to the theory in the IANTD Advanced EANx Diver Student
Kit.
2. This Program must include a minimum of 120 minutes of OW bottom time completed within 4 dives, 2 of which must be to
depths between 100 fsw (30 msw) and 140 fsw (42 msw) If combined with a Deep Diver Program, the total dive time for both
Programs must include a minimum of 160 minutes completed within 6 or more dives. Even if the time and skill requirements
are met within fewer than 6 dives, the minimum 6 dives must be made. If combined with a Deep Diver Program 3 dives must be
made to depths between 100 fsw (30 msw) and 140 fsw (42 msw).
3. Students are taught the use of EANx mixtures to a maximum of 40% oxygen for the non decompression portions of the dive.
To teach the fundamentals of safety and decompression stops EANx mixtures that contain 1.5 PO2 for decompression may be
used. This too is calculated at the deepest depth to which the gas will be switched.


D. Equipment Requirements
1. IANTD Advanced EANx Diver Student Kit.
2. A safety or decompression gas cylinder (if used) rigged as either a pony or stage cylinder. Gas cylinders must be oxygen clean
and oxygen serviceable where needed.


E. 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 140 fsw (42 msw).
3. All dives must be conducted using EANx (maximum 40% oxygen). PO2’s as high as 1.5 may be used at the decompression or
safety stops. No dives made me made with any PO2 greater than 1. 5.
4. All appropriate safety or required decompression stops must be performed.
5. Mandatory decompression stops are limited to a maximum of 15 minutes.


F. Water Skills Development
1. A confined water session must be completed before conducting any OW dives.
2. Demonstrate proficiency in a variety of dive techniques and employ precision buoyancy control.
a. Swim in a simulated out-of-air situation (without breathing, and exhaling slowly) without a mask for a distance of at least 50
feet (15 meters), and commence gas sharing; or appropriate Rebreather gas management drill for out-of air diver. While
gas sharing, swim for 3 minutes, then replace and clear mask.


3. On an OW dive, demonstrate dive planning abilities, especially for avoiding CNS exposure risk.
4. Perform a gas sharing ascent using the alternate second stage.
5. Perform valve shutdowns on each dive.
6. Deploy lift bag 2 times, using it as an ascent platform.
7. Demonstrate a safe attitude and awareness to the Instructor’s satisfaction.
8. Remove and replace tank and BCD at a depth greater than 20 fsw (6 msw).
9. Remove and replace tank and BCD at surface.
10. Demonstrate acceptable navigation / orientation abilities.

Andy...I am thinking deep diver course first then advanced nitrox. I am assuming the deep diver course is the basic entry level deep diving course. When you get to the advanced nitrox I think you will absolutely love it. It is your basic first step into using different EAN mixes. It also goes into alot of other skills...gas switching, gear configurations, emergency scenarios. It gives you an entry level exposure to stage bottles. It goes more deeply into the physics...It is a fantastic course. But do the entry level deep diver course. You don't have to but I just think it's the right progression. Have fun...I would go with TDI I gotta plug my agency...The best!



Jason...My goodness...Did you get that reply published?...

 

[sbrooks]

If you read the red stuff in Jason's second posting, you need to have your advanced nitrox BEFORE you can get your deep.

Looks like it's the other way around.

 

[JKSteger]

I'm in the same boat. I would like to get some basic deco & accellerated deco training in at some time too so this thread is great for me too.

I would go the Nitrox route. Do Nitrox and adv Nitrox, deco procedures and on to other gasses. There is no need to do deep air course. TDI has a nice path for this.

But what is your goal? If it is just to do another course, any course will do. If it is to go deeper, then take the shortest path and get a good instructor. The courses are pretty much all the same (the diving is the same), and if you are lucky, the instructor will teach you a lot that is not in the books. The certifications are just to get gas, the instructor signing you off is your 'you are okay to do this type of diving'. This is more and more apparent when you go down the tech route.

I would go the Nitrox route. Do Nitrox and adv Nitrox, deco procedures and on to other gasses. There is no need to do deep air course. TDI has a nice path for this.

First, combine deep with advanced nitrox. They combine nicely with TDI and IANTD.

For Meng - The deep class is a standard rec deep class. Max depth 130ish and no deco unless taught with adv. nitrox. Its not what I would call deep air. (that the technical nitrox class)
