I am a new diver, and all of my dives to date have been off a dive boat in the Caribbean/Florida. For the most part, they have been with certified PADI instructors/divemasters.
However, this last dive trip I went with a group that was SDI/TDI certified. We explained that we were newbies, with only our PADI OW certification that allowed us to a max dept of about 60 feet.. however, it was my understanding we could go deeper as long as we were accompanied by a divemaster.
There was what I believed was an appropriately certified crew person who said she would guide us on a dive to a wreck at 100 feet. We stayed down for about 30 minutes, but did extra stops on the way up.. 1 minute at 40, 1 minute at 25, and 4 minutes at 15. This instruction was given to all divers on the dive.
When I later looked at my dive tables and log, I did not know how to fill them in! The tables did not have a pressure group for 100 feet at 30 minutes.
Later we talked to the group about what actual bottom time was.. some said it was from when we entered the water to when we got out.. others said it was until we started to ascend, while still others said it was everything minus the decompression times.
Can someone advise me exactly how bottom time is calculated? And what should I have used when filling out my log book using the PADI tables?
It is my understanding that PADI tables are for no-decompression diving.. but it appears that this SDI/TDI group took us on a decompression dive.
