Use what works for the mission. Surface supply dives in shallow water with AGA: that weight belt hurts after a couple hours. Mix of hard weights on the belt and soft or hard in the harness (no BCs on shallow dives like this). The harness helps keep some of the pressure off the lower back...

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...

Oh now and then. I find just closing my eyes and working makes me less disoriented when in zero viz. BTW I will simply not dive zero viz without surface coms and a hard line to the surface (preferably through a surface supply line). Doing it in recreational gear is bad juju unless you're in...

I use them at work. I could dive tham all I wanted recreationally free of charge. I dive bite reg scuba when I'm diving recreationally, as does every PSD I know. \ Man up. Bite reg is not that cold.

My wife and I dive PP2s when I dive with her, which is mostly all my recreational dives (in fact most of our gear is identical to ease maintenance and spare parts issues). I have a Suunto Stinger I dive with at the same time. I carry a simple guage in my spare parts kit. It will get swapped...

I think underwater wireless coms are notoriously unreliable.

I've seen bad things happen to FFM users who had little or no training. This is not something you just throw on and start using. You might get away with that for awhile, but there are any number of problems you need to be able to handle that require training. There is not much of that...

Oceanic is working on a hybrid that flows air to a vest type configuration on the surface and, when you fin yourself into a horizontal position, to modified wings on the back. Apparently they are shipping a female only version of the BC now and a male version shortly. A rep showed me the...

Good luck getting that out. In reality, your exam by the opposing attorney would be a series of short, clipped, yes or no type questions. His job is to make you look mean and negligent. He will. Your attorney's job, on cross, would be to get the facts out of you that make you look better...

When you get it back on your face you have to purge. If you forgot to close your eyes it hurts. If you remembered to close your eyes it blasts water and, as the water clears, air up your nose. You're holding down the purge button for awhile while this is going on, that's a lot more volume...

AGA's don't fog because of how the air is delivered across the mask face plate. Removal and recovery is not easy, esp demand AGA's because its free flowing until you manually shut it down. A bite reg second stage around your neck helps. Get it in your mouth ASAP, then take your time...

Removal/replace/clearing procedures are also much more complex than with straight scuba (as well as rather painful) and its not something you can practice at depth without ruining the coms gear.

I dive AGAs and hats for work, but do plenty of warm water recreational diving. Just not worth full face in my opinion for recreational dives, unless maybe you're really dead set on using coms, and I can't imagine using coms on warm water dives. 'Course my wife is my dive buddy for all...

About 25 feet from the deck of a large ship wearing a commercial diving hard hat, no fins, no bouyancy control device, and about 35 pounds of lead. There was 75 feet of water under us. You really have to trust your tender will let out enough unbilical to let the water cushion you but no so...

How does that prove surface supply "doesn't always work?" The surface supply was working all the way till when the line snapped. An untethered diver on scuba would have been "slurped" up as well, the only difference being no one would have known until the guy didn't surface a half hour later...

As to your first point, are you disagreeing with me as to the % of people of the dive population into tech diving or my notion that basic recreational scuba divers (AL80 divers) should have ditachable weights? I think we would disagree on either point. As to your second point, as I said...

Drowning is never survivable. Basically, on the macro level the entire disagreement comes down to this: The non ditchable camp seems to be more tech oriented divers who are doing deco obligations and are willing to rely on self rescue for all their problems. Assuming the validity of...

My wife and I both have ProPlus IIs. I was issued a Stinger through work. My recreational dives with my wife tend to be remote locations where we cannot buy replacement parts. I dive the stinger and PPII together and carry an analog SPG in my spare parts kit. If either PPII fails, I'll plug the...

This math makes my head hurt. Just send me another lift bag.
