Going with the Dive Rite Nomad LT Cave. Also getting some Faber LP 75.5 Cu ft tanks. 6.75 inch diameter with new hydros and vis. Plan is to use them or a couple al80's with it. Just got in my valves and reversible HOG second stage. Looking forward to getting in the water with it thanks to a local shop owner I work with from time to time. Then in a month it's Doppler's SM workshop at Gilboa. Will be taking it and if needed helping him with other participants. This is something I've wanted to for a while for a number of reasons. I want to offer it in the future to some of my students with back and knee problems that have issues with back mounted tanks. being able to just wear a harness in and out of the water and clip tanks on and off may extend the dive life for many people. I've been diving with slung bottles for years with my doubles. But I realize that proper SM is something different so it's little steps and proper instruction with as much practice as possible.
