Agreed on the husband/wife *team*... been there done that. I just let him go.

novadiver:Three diver teams are fine in open water, but in a cave or wreck the " team " just added more failure points in their gear. When I'm diving in a group of three I make it known that I'm the solo third diver, They should dive like a buddy team and never look for me.This takes all the stress out of their dive and works well for me.
I'm not trying to highjack the thread, But there are several dives that just don't work as a three diver team. Most of the dives are very advanced and should not be tried by any diver that isn't prepared to finish solo

If the third diver in line , is in zero viz, than there is no use in being there. That diver adds risk just because they are in the water, and they can't come to your aid because they can't see, But I will agree that these dives are more technical in nature to start with.trob09:The glass is half empty, eh Nova? Those same 'failure points' can also be seen as additional safety factors.
Pug is right though, it requires a team-minded approach rather than same water/same day diving buddies. With a true team, it doesn't really matter if there are 2 or 3 divers. The challenge - I've found - is to have that team approach hold true as dives get more serious.
I am fortunate to have found a buddy who shares the same mindset on our dives. By that I mean not just protocol on things like order, signalling and deco proceedures, but also interest and pace. We generally look forward to doing the same things on dives at the same pace. It is truly a joy to dive with this buddy and I would prefer to dive with him anywhere.
We have had a 'third' on many of our dives and I have been on other teams of 3. While this has always worked, I notice an increase in divergence as the dive challenge grows. simply put, the more serious the dive, the more individuals want to follow their interest. And when you're talking about $1,000 boat fee and nearly that much in gas for a deep technical charter here in the NE, I understand that desire. It's one thing to have an instructor or senior diver leading a couple of other divers. It's another to have 3 equally skilled divers share a plan AND a mindset.
The problem is that these are the very dives where the team approach has the biggest benefit. So, to answer Mike's question, Teams of 3 can work and work well. My experience is that it's easier to have a 2-person team on the same page in more complex/serious dives.

Push, pull, sqeeze two times, figure 8 in the hand, works well with two divers, but three divers doing zero viz touch contact signs are burning through gas quick and slowwing the exit, that's a bad thing in overhead. Three diver teams in open water pose no additional risk( imo) but three diver teams are not always the answer in any overhead ( wreck, sump, cave or well )trob09:If your mindset is that other divers are a liability, it's better that you stay solo. I choose to believe that my buddies are assets and treat them that way.
It's pretty easy to make vis go to 0 inside a sub at 230' or wreck at 250'. I have had no problems with maintaining buddy contact and communication in those situations.
If you want it to work, it will. If you don't, it won't.
gas and deco mix - yes. Sac rate, not necessarily (answered later)novadiver:But the three diver team question does lead to other questions , do all the divers in the team have the same sac rate, gas mix, deco mix.
The team stays together.novadiver:Does one diver stay outside and let the other two penatrate.
No, the plan does not change, the first diver to thirds turns the dive.novadiver:Does the gas management plan need to be changed( or is it , the first diver to thirds thumbs it )
Probably best you stay solo. Someone with this mindset is a detriment to the team, especially when he insists on "being the last in line" and doesn't believe in the team concept.novadiver:All things concidered , I'll stay solo or be the last in line for the three diver team
