So do you need a twin-set for 30m dives?
You don't need any of them but manifolded twins give better redundancy and are better all rounders in that they are more capable than a single and pony.
I have one 12lt twinset now as I have sold everything else. These are perfect for going and doing my two "normal dives" on a normal diving day with everyone else like yesterday or for my trimix/deep doing in conjunction with stages.
My wife has a 10lt twinset and only dives what would be classed as club diving (ie two dives in day to a max of around 30m or so)
the main advantages are -
Kit gets set up at home so very few failures as it has been put together in no rush and checked.
I only pay £2 for a fill for a full days diving.
The kit gets put on the boat and is not touched except to dive, no messing about changing cylinders etc.
Lots of redundancy and plently of air
Easy to dive, one SPG, one reg getting used.
With a long hose on the main and going onto the backup reg, one SPG to monitor.
One set of kit does all.
And many other minor ones.
ps I only boat dive so I can see the advantages of a single if shore diving a lot
