We need some more conversation in here. I'm curious as to how many of you guys treat rock bottom when you have a multilevel profile. It's geared more towards a simple single tank dive and not necessarily a thoroughly planned technical dive.
Do you treat your rock bottom pressure as static or dynamic?
Personally I treat it as dynamic based on the profile I'm diving. For example, a dive on a live aboard in turks and caicos. The dives typically start out at around 50-60 feet. We'll typically follow the ridge of the wall away from the main dive site to where the reefs are healthier until we reach 2000 psi, turn the dive and head back until we are back under the boat. By this time we are at around 1000 psi and at rock bottom for our depth. At which will typically do a minimum deco ascent and goof off under the boat at around 10-20 feet until we get bored and get back on the boat. I've been known to get back on the boat with around 300-500 psi after this. If I treated rock bottom as static then we would have planned the dive so that we were back on the boat with 1000 psi left, based on rock bottom for our maximum depth. Thoughts?
