Then I went to stacking cylinders on the left --- it took about 3 or 4 dives to move some things around but now --- its pretty simple --- the biggest problem ocean divers have with stacking tanks is the physical position they are in when sitting on a boat waiting to get in. While sitting I have one attached -- then stand up clip the next on and jump in --- its pretty simple This year i went to having all students stack on the left --- and they have no problem with it --- especially with 40 cube bottles --- but we also have them stack 2 80s also --- aluminum bottles work best -- they are easier to move in the water than steel -- sure it takes a little getting used to --- but balance is rarely a problem when set up properly. Having one side free makes doing so many things easier -- especially gas sharing drills. I belive that a diver should be able to do both unilateral and Bi-lateral methods -- but the unilateral is the preferred method.
