first deco dive

[Tortuga68]

I've done 2 deco dives in a day more often than I've done just 1

My last deep dive workups were (all deco dives unless otherwise noted; all deco dives are on air as back/bottom mix with 50/100 stages for deco):

March
Day 1 - 43m (no deco)
Day 2 - 50m & 32m (no deco)
Day 3 - 50m & 55m
Day 4 - 65m & 70m

April
Day 1 - 46m
Day 2- 50m & 19m (no deco)
Day 3 - 55m & 23m (no deco)
Day 4 - 55m & 65m
Day 5 - 64m & 75m

July
Day 1 - 45m & 55m
Day 2 - 30m, 37m & 31m (all no deco)
Day 3 - 18m (no deco)
Day 4 - 33m (no deco) & 65m
Day 5 - 75m
Day 6 - 29m & 19m (no deco)
Day 7 - 85m (birthday dive!)

That's what's in my logbook anyway, the days might not be exactly right as I only filled it out later - but the order is right. SI between deco dives is usually 2-3 hours, with the runtime cut on decoplanner as a series of 2 dives (where applicable)

I dunno if I should put a disclaimer on this or not - people complain either way. Anyway, here it is: I suggest you don't do deco dives without proper training/mentoring/understanding/equipment

2 questions: what is a 'bounce' dive and what is SAC?

"bounce" is fairly descriptive... drop to a desired depth and come straight back up.... "Tag" would work too


SAC - Surface Air Consumption... useful for predicting gas utilization

2 questions: what is a 'bounce' dive and what is SAC?

For commercial diving companies (and that's what I meant) a "bounce dive" has a rather short duration (from one minute up to one hour) at the maximum depth, compared to a "saturation dive" that lasts for days or weeks at working depth.

As I mean it, it can be more (much more) than just a "touch an go" which is a "short" or "weeny" bounce.

SAC, as already written, is Surface Air Consumption. Fundamental for gas management.

My two cents on the original issue: For anyone that progresses toward agreessive dives flirting deco, or "tech-light" dives with small decompression obligations, keep in mind that you have stepped over the line that you are trained to handle. The temptation will be to step further and further over that line with longer, deeper dives with more deco obligation and as long as nothing bad happens the temptation will remain to go even further. For those that find themselves flirting the recreational limits, I say just get the training.
