    Was talking to a representitive regarding pairing ADV Nitrox and Deco Procedures, and I was looking more at the course flow chart and the Helitrox course looks good also and seems that you can take it in conjunction with ADV nitrox.

    Question is with what I saw the Helitrox has some of the same elements of the Deco Proc, so do you also need to take the Deco course or does the Helitrox cover it with the added element of HE in your mix?

    Hope that makes sense.

    Thanks

    I'd do the heliotrox class as its essentially the same as the Deco procedures class yet adds helium. It gives more options.

    Helitrox includes all of the components of decompression procedures, there is no need to take both courses.

    Helitrox is just DP but you use helium in your backgas.

    Although to be honest, with the latest studies showing that the "helium penalty" is a load of c**p, I don't know why there's even a separate course. IMO, normoxic trimix shouldn't require a card at all. If you can perform to the standards required to achieve your DP ticket, you should be good enough that trimix isn't an issue.

    Hypoxic, absolutely, normoxic, not at all.

    I can't see any reason not to add Helitrox to your AN/DP course.

    Tell me what issues you think a diver would have running normoxic trimix as opposed to straight air or nitrox for any of the actual dives for AN/DP.

    The fact that it can be taken as a "replacement" for Decompression Procedures shows that the required skillsets are equivalent. Hell the standards are almost identical except for some added lecture stuff about the benefits of helium. They've already proven there's no such thing as a helium penalty, which was the impetus for treating them so differently in the first place.

    And if a diver doesn't have their fecal matter situated BEFORE they do the actual deco dives of DP, helium isn't going to change what happens, and realistically they shouldn't even be at that point anyway.

    This is the agency forum, so not really the place to be debating the finer points, but I will say a few things.

    Going from AOW no deco and a max of 130ft, with 50 dives under your belt, to doing decompression dives using trimix to 200ft is quite a jump. I have no problem with teaching trimix in a deco course (I do teach a combined helitrox/deco course, and prefer to teach it that way). My issue is more of the depth, because in a helitrox course most agencies max out around 150-160ft which I feel is reasonable, but going instantly to 200ft is quite a jump.

    Thanks for the input and I agree this is not the place to argue the point plus that was not my question and it has definitly been answered. My wife and I are mainly looking to extend our dives in the 100-130 foot range on wrecks but also would like to increase our depth too if need be. I just noticed when reading the courses that the Helitrox and DP seemed to be the same but add He to the mix. I would rather have that and really that has make my decision for me. Again thanks for the input everyone.
