The student's do some form of navigation, in varying difficulties, on all dives in the class. It may be taking us back to shore from some random point in the dive, to leading us to a specific spot, or getting us home on the night dive. The navigation specific dive, however, is a mid-water...

Sorry, misread this (missed the 50ft part).... 2 experienced divers can expect to use approx 750 - 800psi, sharing a single tank from 50fsw, with a 3 minute stop at 15fsw.

Not sure what you're referring to, but 2 experienced divers, sharing a tank, can expect to use about 400psi at 15fsw and the following ascent, and that's IF there's 500 psi in the tank. Once tank pressure falls below 500psi, spg's are horribly inaccurate. That is cutting it way too close for...

This is controlling the pace of the descent to the slowest diver. Anyone can descend alone, at their own speed, meeting others at the bottom. Descending/ascending together, prepared to offer assistance, can be quite challenging at first.

I don't see any adv nitrox/deco material in his post. What are you referring too?

Realistically, I don't expect every student to walk away from the class adhering to Rock Bottom like the bible. I don't like 1/3rds, however, as I think it's way too dangerous for some divers, and can be quite conservative for others. A general rule of thumb I give my students is to never...

That's why I made my own test :D

Personally, for my class; Horizontal descent, face to face, not touching the bottom when reaching the bottom Proficient buoyancy control and trim thoughout the dive, even when tasked (OOG, mask skills, navigating (some degree of navigation is done on every dive) Horizontal ascent, face...

I think that would potentially get a lot of divers into trouble.

I spend about an hour to 90 minutes on that. I cover that in Advanced, Nitrox, and Open Water.

And there may not be anything wrong with it. But how does the student know if it's safe or not? In my Advanced class we determine every student's individual SAC/RMV. In one particular instance, one student's SAC rate was so high, that his Rock Bottom for 100' was 2900psi. He'd hit his RB...

Which paragraph?

You don't have to teach all the compartment models, but if you have a basic discussion on slow tissues vs fast tissues, and how minimum deco will get you out of the water much cleaner than the tradition ascent profile, it's pretty easy to grasp.

I have to disagree with this. Presented properly, an instructor can let the student come to his/her own conclusion that diving to 100' on an al80 isn't the smartest thing to do. A discussion/presentation on basic gas planning and management makes that abundantly clear.

Since the deep dive is one of the madatory dives, in addition to gas planning and management, bubble management needs to taught as well...Buhlman vs minimum deco, etc.

Awesome! Great to see this forum here ...

Bob (NWGratefuldiver) has taken some amazing pictures up here as well. You may want to look at his gallery or search for his posts...

Wow, if that's true that would be awesome. I've been wanting to dive the bomber for quite some time.

Congrats! I'm not familiar with the specific requirements and functions of the Divecon, but I believe it's similar to a Divemaster. As a DM, you'll be in a leadership position and will be responsible for certified divers and students. It's in your best interest, as well as the students...

Works for me!
