Ice Diving

[mndiver]

Hello all you ice divers....  I posted this question on MNScuba and did not got much response. I hope I can get more here. 

I really love ice diving.  It is great to drive up to the dive site and jump in.  No boat to tow, better vis, no $@*#&$) sailboats!  What's not to love?

In an never ending quest to satisfy my curiosity I have a question.  How do you ice dive?  What procedures, equipment, percautions and so on do you use?  Any books on the subject you like? Best place to get gear?  I have heard of several methods from; two down on one rope, one down using a cave reel, one down on one rope, attaching the rope below/on top of the ice and so on......  I know how I do it, but it never hurts to learn from others.  So again, how do you ice dive.
