A fairly common practice in shore diving is to do surface swims (sometimes longish ones) to a drop down point.
Sometimes this may be unavoidable as when at a shallow dive site but since exercise and diving don't mix that well regarding bubble formation isn't this a rather poor practice at deeper sites where more nitrogen will likely be ongassed in the course of the ensuing dive?
If the Navy has divers exercising to be able to quickly get the 5% hits for table research it strikes me as odd that so many divers begin many shore dives with surface swims where they aren't totally necessary..meaning that they could just drop down at the beach and just use more gas.
What are your thoughts on this practice. Is it not enough exercise to be meaningful or should it be reduced?
