Hello all,

I haven't dived a rebreather but would love to when cash prevails....but in the mean time, could anyone help with a few questions? I have been trawling various sites but one or two short answers from those at YD could be useful.

I know so little but can someone sweetly explain the various rebreather options, OC, trimix etc. OC vs CC is OK...I have that sussed in my head.

I am a bit curious, knowing little about rebreathers at this time but, I understand that the comp on board top range models, will adjust the pp of O2 as you descend/ascend. Am I right in thinking that the trimix rebreather does exactly the same as diving trimix OC and just keeps the N down?

Also, what happens with a big helium load....surely that can bubble too....any posts ot thoughts on that?

Thanks all.
