Hello All,
With regards to the posting asking about Mares MR12 Rigs, I have a couple of comments, one nice and one not so nice.
Firstly, the first stage and the assocated second stages are wonderfully light and small.
I bought it because of this fact and the fact that it was relatively cheap.
However this rig is definately not to be used in colder waters, it really doesn't deal well in my experience with waters of 10 degress or less.
So much so, that after a free flow at 30mtrs, I have now gone out and bought the ScubaPro mk25 and X650, which are definately suited to the colder waters.
I don't see the MR12/16 being an issue for diving in sydney, but just wanted to point out that it's a point people should consider.
Paul
