Need Help with TDI Courses

[airmonkey]

Hi,

I'm planning on doing TDI advanced nitrox and deco proceedures this coming summer (so a good few months off yet) and was going to follow this on with either the extended range or the entry level trimix course but out of the latter two I don't know which is best for me to do. Ultimatly I am aiming to go on to the advanced trimix but not in the immediate future or so.

So what would be the pros and cons of the two courses? Stick to the extended range and leave the trimix til later or do the entry level trimix?

Thanks in advance

The Adv. Nitrox and Deco Procedures are the best two courses I have ever taken. Find an instructor with a few thousand dives who goes to deep, dark, cold places for fun and make these courses count.

I would not suggest you bother with the Extended Range course. Air to 180' is pretty much widely recognized as a bad idea. Entry Level Trimix will be a much better way to go. You would likely be narced A LOT at that kind of depth on air.

My deepest dive on air (or period) has been to 160' and I most notice the martini effect when I descend below about 140'. Not drunk or freaking out but I can definitely feel the buzz. As we all know, not a good thing considering the environment. A good instructor would discourage you from the Extended Range course.

thanks for the heads up i was interested in taking the extended range. my instructor even offered i could jump up to advanced recreational trimix with only a nitrox certification. been doing a lot of sitting in and know quite a bit about these procedures. its not common to jump pre-requisites but its the discretion of the instructor

I would also recommend against extended range. It's best to do adv nitrox & deco then get 50 dives or so, then progress onto entry trimix. I'll be doing entry trimix early next year. I don't feel I'm completely ready for advanced trimix, so entry trimix will get me to the wrecks I want to go.

The next course I want to take is entry Trimix. I see no reason at all to take Extended Range.

I agree with what everybody else about the extended Range course, go strait to entry level Trimix. In the old days (early 90s) a lot of Divers/instructor thought it was a good idea for a diver to learn to dive deep on air before moving to trimix. It not the case anymore. We all know that deep air diving is dangerous even at depth around 160ft.

starting to look as though the extended range has no redeeming features?

thanks for all the info

I've been through the extended range course and was very glad I did for a number of reasons. If you ever happen to dive in a part of the world where helium is not available, such as Truk Lagoon or Bikini Atoll you will have the training to maximize your experience.
