I know the adage plan your dive and dive your plan which becomes even more true when you are tec diving. I am not tec yet and maybe this is something answered in the training. I am not looking for specific answers as I am not planing on doing this type of diving until we (dive buddy) get to that point but trying to understand better how it would work.
I know most dives are planned in the fact of the "wreck" sits at 200' so you are going to go down to the wreck, spend XX amount of time. Based on XX amount of time you have a set Deco profile.
How does it work when you want to explore a new area? Say you don't know exactly what depth you will be at or for how long? Do you just set a max depth and time then stay within that?
Here is an example of why I am asking. Right now we have a train wreck that the upper car starts at about 80 FFW (depending on water level) and the lower car sits about 112 FFW. There are rumors there are more cars that lay deeper. On air this only gives you ~ 10 min bottom time (NDL) to explore is not time to get much done. When doing a search like this obviously you can set a time limit, but what about depth when you don't know how deep you are going to be?
Again not looking for exact answers as it is not something I am planning on doing till trained, just curious. In our area we have lots of unexplored areas so trying to get an idea of how to safely "explore". Our plan is to go CCR but OC answers would be great too. Here is the information I have on the train wreck site, from my website Scuba Dive Sites - Trestle Creek
