Fitting 3 Way Block and Blanking ADV

Dave1w · June 8th, 2012, 07:11 AM

I bought a 3 way block thingy with orifice for my Classic as I like the idea of a proper manual dil add. I am toying with the idea of blanking off the ADV now, mainly because the manifold I am using only has three outlets, so it saves me getting more complicated with hoses and connector. Other than that I have never had a problem with the ADV, other than it being stiff.

I have the 2 addition options remaining with the BOV and the new manual add, but there is that slight worry of not being able to add dil hands free.

I guess the early inspo's got on OK without an ADV, does anyone else dive without one?

I've dived without one and as with all things it's fine. But I would not be without the ADV now.

The only time I dive without the ADV is when I off-board my gas for blue-water gas diving - and it's OK, but I like it when I get back on the ADV.

I'm not sure what you've bought...picture?

I see this is the KISS forum so I assume Classic KISS (not Inspo!).

I dive without one, due to reasons I won't go into...
In short I like not having it although would prefer to have one if I could but it has helped considerably with O2 and DIL usage and helps you know what your buoyancy is doing rather than having to look at the handsets. It's a future criteria on any CCR that I have manual shut off for the ADV but having one would be nice if I spent over.

The down sides are obviously the descents are busier but not intolerably so but also any activity where you might loose loop volume while trying to do something like a boat collection or loss of buoyancy while doing something. In these instances you need to plan ahead, give yourself a good burst of gas and avoid the loss of volume by accident as it's no fun having crushed lungs while trying to get back on the boat.

As I dive mostly hypoxic gas then I consider the flow-stop mandatory. I switch off as I start the ascent and keep off till back on-board.

It's one of the things I don't understand about folks with ADV not having flow-stops. I'd prefer no ADV than ADV without flow-stop and hypoxic gas.

Dave,
try this: remove the ADV hose and adapter and plug it with a 3/8 unf first stage plug. Go diving. If you like it, leave it at that. That gives you the possibility to revert.
Now, I dove sans ADV my Azimuth for some time but as soon as I got the opportunity to add one, I did.
Best

Due to a problem with my counterlung too complicated to explain in a sentence, I sometimes end up without an ADV as well.

It isn't the end of the world however I'd rather have one than not.

My onboard is always my hypoxic dil so just turn off the onboard and have the off board available with shutoff in the shut position during ascent. If I had to BO then it's just a turn of the shut off to get gas.

I am not diving deeper than 90m at the moment so that works fine.

Hi Dave... My triple gas block with orifice arrived on Friday... I fitted it yesterday and am going to try it in the pool tomorrow. I have disconnected the ADV. Like you said I still have 2 means of adding dil... BOV and MAV on the block. I'm going to try it and see how I get on. Its integrated really well and looks nice and neat... I'll let you know how I get on..
