Many times agencies end up with multiple courses when it appears there should be one. A good example is some of the gas blender courses. Why make trimix blending a separate class? I am under the impression that the GUE introduces trimix and other things earlier than other agencies. They still have multiple tech level classes. I would assume the limits progress at each level. I think the arrangement makes sense. I also think (hope) that the trend in training will be to introduce He sooner.
The IANTD Advanced Nitrox and Deep Diver course combination are meant to introduce redundant equipment, more in depth dive planning and deco procedures. The course takes place at or above 130 ft. The student develops important skills at recreational depths. When I teach this course combination there are several classroom sessions, at least one pool session, several shallow dives (confined open water) and a bunch of dives. I have dedicated sessions for assembling doubles, introducing dive planning software and configuring equipment. This course is a real culture shock for some students. At this level you cant make any assumptions about prior knowledge or attitudes, therefore there is just reams of info to cover. Most students really have their hands full. This is not a one-weekend class. To add more would obviously increase the length or task load of the class.
The next level is Technical Diver and Normoxic trimix (old name intermediate trimix). In the Technical Diver course the max depth is 170. I took Normoxic trimix right away because I didnt like 170 on air. Combining the two courses sort of fixes that problem though.
I think you will end up with multiple classes regardless of how you organize things. I will not dispute the GUE max END of 100. I like mix myself. With a max END of 100 you are forced to use mix earlier. However, there are many rec divers with little experience and inappropriate equipment going to 130 and beyond. Talk about END trouble.
Without comparing them to other agencies, IMO the IANTD curriculum, when administered as intended, is very good.
