In a nut shell we have you doing a dive without any means of counting for depth or bottom time. OK, not problems here. Your life, your dive. You diving without a means of counting for depth and bottom time and posting about where we have new divers reading about it is another situation all together.
I knew the depth because there is a cave line and the cave line is surveyed and verified and personally dived that run in that cave 400+ times.
I knew the time because I know the time it takes to run from waypoint to waypoint in that run in that cave whether it is by scootering, swimming, or crawling through the silt. Time need not be accurate because there no deco requirement can be incurred in that run in that cave on the available gas. A knowledge of time was only necessary to make sure I was not in a SPG stuck situation.
New divers can understand that, and furthermore can get a glimpse at the importance of a cave line in a cave, and in any event can learn at par with me about a mistake I made, if I made one.
I could have miscalculated that dive, that day, but I did not.
In that cave that dive that day to have or not to have a Dive Computer/Bottom Timer was inconsequential/immaterial.

one thing I think we all can agree on is that it's a bad idea to post it on an open forum.
Why not post it?
It was pertinent to a different thread where I originally posted it as it was an example of a calculated risk.

If you truly believed that, you would never use a computer or bottom timer. If you don't need it, why do you ever carry it?
Pure nonsense.
I carry it because I need to know depth and time and in 99.999% of the situations without one I cannot know depth and time.
This was a particular situation because the cave was surveyed with a line and I dived that run 400+ times (depth and times won't change and would be known for that run).

He included that information on the first page.
"Went in 600 meters, then back out 400 meters, then back in 200 meters, then back out 200 meters, then recovered the jump line, then around and about here and there within 250 meters of the entrance, then went exploring a line the very last bit (leading to a small dry chamber) I never dared to follow before with the rebreather due to size/buoyancy considerations, and then got out (having had more fun than if I had done my otherwise planned exploration rebreather dive for the day).
Pertaining to a map is one thing but doing it for the first time is different.
As explained, it was a line going into a dry chamber.
Really no big deal to follow a line to surface into a dry chamber (if you enter the chamber carefully at the right angle not to dislodge mud/stones...).
It is exploring (visually) a dry chamber, but the line goes from a known point at a known depth to another known point at a known depth (surface)... about 20 meter run at a 70 degree angle beginning at 10 meters and ending at 0 meters.
Worse case I was at surface off-gassing - a non-risk relative to having no Dive Computer/Bottom Timer that day.
P.S. "Turtle Nest" is just a name I made up to get you off from repeating asking for information you won't get... call it innocent disinformation!
