RDW, Hi. I'm switching to 12v for the same reasons as others have eloquently expressed here. Also, my
Alberg 35 doesn't have space to stow a clunky, stinky, soon to be rusty, gasoline motor/compressor rig. My
diving interests now max out at about 30ft, where, as others have said here, the best scenery is. Been there done that at 100ft +, and survived.
One additional note that has been missed or misunderstood by other posters in this thread, is that toxic contamination of compressed breathing air is very dangerous b/c of the increase of partial pressure. The smallest amount will sicken/incapacitate you at
depth, you don't want to hear the fat lady singing that song . IN my original
posting I truthfully stated that we got away with an informal rig, and now re-reading my post, I realize I should have included a caveat to take more care to prevent
exhaust contamination.
