since it's almost winter and there will be no more dives for me this year it's time to think about next summer and buy/build gear.
spearfishing went great this summer in the black sea, caught mostly small fish but tons of it, and i was trying to think of a way to extend my time under. most of the times i dived was under 25 ft, since most of the fish inhabit the shallow waters. personally, i hate going up for air, even if i only do it through the snorkel. for me it ruins the whole experience of freediving or underwater hunting, it takes away most of the freedom.
now i don't want anyone calling me stupid for what i am about to ask. i haven't done any research, and i am asking here because i thought that if it's impossibile, or harmful, it's better if someone tells me straight up than if i find it out through research or...practice (might cross my mind you know....). so here goes:
if i only had to go up to 5 ft or 10 ft to get air, it would be perfect. then i could probably stay under a lot longer (preferably at least 3-4 normal dives' time). so i was thinking of attaching a fine piece of tubing to a small diving buoy. on the sunken end it would have a one way valve so that no water goes in. also a weight close to the end so that it would hang down in the water, not float aimlessly.
now my questions would be....
1)are human lungs strong enough to bring air down to a certain depth (or do i need a small pump??) ? what depth would that be??
2)what depth would i have to be at so that the surface air would not be harmful to me?
3)how long would it be safe to be submersed like this for?
