    SSA (Surface Supplied Air with SL-17) is best, the others are second best, in part because they do not provide full encapsulation.

    Another option to read gauges etc is to fill a small ziplock with some clear water. when you need to see your gauges just hold the baggie against your mask and then position your gauges on the other end.. now if its black.. do the same after you hit your gauges with a light to get them to glow... keep in mind... I have seen it tooo dark and muddy for this to work..
    good luck

    Yes, surface supply just for black water. The whole point is you don't know what's down there and surface supply, done properly, gives you a virtually unlimited gas supply. It also removes gas management from the diver, letting him focus on diving.

    As has been pointed out prior, it is far more gear and personnel intensive. We need 6 people absolute minimum to put two of them in on surface supply. Longer to set up, much more training needed, but it is really a quantum leap in safety and efficiency (given that most PSD dives are shallow enough to not need tables, you can work for hours and hours). You also have the most trouble free coms system you can have.

    I've penetrated into some overhead environments, once in true black coffee water, that I simply would not have done without surface air.

    We only go scuba/aga with a 100 or 80 plus a pony on a hard line coms tether when its essentially a bounce dive to an already located and roughly identified target.

    Hey bleeb..... there are no stupid questions.... but I have been on a recovery dive and the vis was so bad even with my flourscent gauge and a light I was unable to read my gauge... We ALWAYS have a tender and in really bad vis we use a 30 min cycle.... some guys don't hardy burn any air and some burn 1000psi but it is the safest solution to the "black water" problem that we have come up with.
