I did sort of "poor mans free immersion" two weeks ago in Dahab... I had the idea of doing a free immersion dive head up, asked Lotta to hand me over her 6kg weight belt and went down to 45m with 8.5kg (6kg plus my 2.5kg) and my old 3mm. I found it funny until I started the ascent. I soon realised that I was a LITTLE overweighted, but didn't want to drop the weight belt(s). "poor mans free immersion" I'd call it. It was 45m only... seemed like 100m to me though... I made it clean to the surface but my arms burnt like hell.
