A few buddies and I spent this past weekend at Portage Quarry in Bowling Green, OH. The whole time I was averaging about 1000 psi per 10-15 min or so, not very good basically. My buddy Redneck had a pair of Scuba Pro split fins that he ranted and raved on, and I was always saying how uncomfortable they were when I had to wear them for Divemaster training exercices. Well he was occupied with his family so I grabbed his fins and tried them out.
I immediately noticed how I did not have to force the fins to do their job and the relief of strain brought by my straight fins. I also noticed that despite this lack of effort I was still moving at the same rate of speed and it was much easier when alternating between flutter kick and frog kick.
Finally at the end of this dive (I started out with 2000 psi) I surfaced from this 46 ft, 31 min dive using 1500 psi. The relief of work from the fins allowed me to consume less air and I could have added at least 15 min to the dive had I been using a full 80 cf tank.
Needless to say I ordered a pair from LeisurePro. Anyone else had the same epiphany?
