Have a few questions about multi-level dive planning. A little bit of history, I have taken this specialty, so I am familiar with the basics. It's just been a while. I currently dive from a computer when doing multilevel but I would like to be able to plan them before hand for practice. I would also like to take my tables with me as a backup. I don't have a wheel and I'm having trouble finding one. Can I just use the standard tables for planning it with a SI of 0? I tried planning a few and want to see if my math is right and see if its possible to do it this way.
Here is one example I tried.
Hypothetical dive on AIR, Planned depths of 100' (10min) 50' (30min) then 20' (20min).
After the dive at 100 it shows me being a D Diver, ascend to 50' and stay for 30 minutes puts me at an H diver (30 min BT and 29min residual) ascend to 20 feet and stay for 20 minutes. This shows I still get out as an H diver (279 residual and 20 min BT)
Seems to make sense to me, am I way off on this?.
I'm going to continue to dive my computer until I talk to my instructor about doing it this way. But, I would like some input from some of the more experienced divers on here as well .
Thanks,
Terry
