I can easily figure out doing dynamic apnea in a swimming pool with nose-clip + goggles...
but when it comes to constant weight, it is another story...
what should I do with my goggles ?
should I put them on once in the sea, filling them with water directly taken from the sea :waterwork ?
should I bring physiological serum with myself on the boat ??
