Well, today I started training in the pool,, I see I have many things to learn and a long way to go to get back into shape. One thing that really impressed me was the efficiency of my sporusub carbons compared to my old fins. I knew they were better but in the pool I was able to do some real comparisons. There is NO comparison. But try as I may, and I did many times... I never found a good way to turn around under the water with the long fins. Does anyone know of a good technique to get turned around at the end of the pool in both the shallow (1m) and the deep end???
