The Hollis Explorer rebreather should be avoided at ALL COSTS.....it is trash....it gives you few if any REAL advantages of a rebreather yet it increases the risks you assume while diving.
I'm sorry to be so blunt and don't take it personally, I do know a little bit about rebreathers.
As your training allows I'd look at the "tried and true" rebreather list: REVO, Dive Rite Optima, JJ, Megaladon and Hammerhead.
As far as computers go there are just 3 computers to look at when it comes to tech diving:
1) Shearwater
2) Shearwater
3) Shearwater
Your Atomic is a good computer.....the shearwater is THE standard for tech diving with good reason.
If you PM me I'd be happy to discuss this with you, I'm not an instructor and I have no interest in the dive business so take that for what its worth.
The OP didn't say a thing about Tech diving.
