EDIT: Changed the definition of RSDD to allow the use of EAN32 (or EAN36) as both the bottom gas and the single deco gas (rather than limiting to air only).
EDIT2: Changed the definition to allow for EANx (since NOAA has published tables for more than simply EAN32/36. For example, link to the download here: NOAA No-Decompression Tables for Nitrox Dives | Office of Marine and Aviation Operations).
A recent thread has me wondering who among us engages in what I am calling "Recreational Scuba Decompression Diving (RSDD)" by which I mean, "Making a planned decompression dive in a non-overhead environment, using open-circuit scuba, and using EANx for both the bottom gas and a--the only--deco gas." (No stage bottles can be used for extending the dive.)
One of my posts in that thread is: Wanna stay down longgerrr.
If you do this type of diving, please describe the particulars. For example:
1. Seldom, occasionally, or often?
2. Shore diving, or boat diving?
3. Fresh water, or marine?
4. Buddy diving, or solo diving?
5. Rig? (For example: Single cylinder, no pony/backup/bailout? Single w/ pony? Back-mounted independent doubles? Back-mounted isolation-manifolded doubles? Side-mount independent doubles? Something else? What is/are the cylinder capacity/ies?)
6. Exposures you typically plan for (i.e., planned max depth, planned bottom time, and planned deco stops and times)?
7. Typical activities? (For example: Simple sightseeing? Photography? Food hunting? Artifact hunting? Scientific/research diving? Something else?)
I am looking forward to your responses. (NOTE: I am NOT interested here in PSD-type nor commercial diving.)
TIA,
