My drunken eBay purchase has the, frankly horrible, AP bondage kit on it. What do I need to fit my trusty OC BP and wing? Assume for now that I am stuck with the yellow box.

I did this on the one that I borrowed for a year.
It's do-able, but because I knew I'd need to return mine, everything I did was reversible.
The is a danger of the case splitting, but there is apparently a 'steel-rule' fix for this, I don't know if you do the fix first whether it will act as a reinforcement.
I found the biggest ball-ache the fact that the cl's were hard to clean as you can't get them off however there is a guy that'll cut the harness up and put Velcro on (or you can of course).

I also put an extension (not a break ;) ) in one side of the harness.

How did you tether the lungs at the bottom?

I just bolted it all together with lovely big penny washers. Works a treat.

Aquatec do the removable mod for 65

What size?

Mine are medium. I use a bungee loop on the bottom of the counterlung. Simply thread the harness waist strap through the loops when putting the unit on. Works really well.

This is what I did before putting the rear lungs on.....

It works fine....

or if you don't like the penny washers idea get a length of say 30mm by 25mm rectangular acetal and drill some holes in it to space the backplate

I didn't use penny washers as spacers. Just bolted it straight on backplate against plastic case.

Do you need to split the lungs before going to a BP or does it just make life easier?

you'll need to space it off when you put those BMCL's on it that you're secretly lusting after

I did pretty much what Woz does. I'm on the lookout for s Vision now, preferably with BMCL.

Saw a vision recently for 1800. Non AP bmcl 250 off eBay. As I have a Woz plate which has a deep bend on it instead of a normal shallow one, bmcl fit just fine with no special plate needed.

Tbh since I ditched the harness and put the bungee loops on the lungs so I can easily flip them up, the front lungs don't bother me at all. Clipping stuff on and off seems really easy I have no idea what all the fuss is about.

FWIW, here''s what I did. Firstly, get the removable counterlung mod from Aquatec and ask for the loops on the back that hold it onto the harness to be velcro rather than sown on. It's not that expensive and it works brilliantly. First class mod. Secondly, make a normal harness and backplate setup with whatever breaks or extensions you desire but FWIW, I suggest you use Kent Tooling's counterlung d-rings, as they make it dead easy to find the shoulder rings with stage clips by moving them from under the lungs. If you're worried about the box cracking, APD make an adapter to re-enforce the yellow box or KT make a nice backplate stabilising block set that works very well. Thirdly, if you fancy going for something a bit more fancy than bungee, Kent Tooling make a slider that you can put on the harness waistband (2") with a slot for 1" webbing at the top. If you don't already have a pair, the APD 1" shite crotch strap of doom can then be cut down to 2 nice neat pinch clip fittings that go through the two of these on the harness waistband, so you can neatly clip the counterlungs down. That lot together works a treat, looks good and solid and gave me several years of trouble free service!

I just used some 1" webbing, made a loop (stitched) to slide over the 2" webbing waist band I'm using (CD backplate/one-piece harness) then fitted the male clip on the other end & stitched over end so they don't fall off. On the open end of waist band I've a plastic weight belt retained clip so strap doesn't fall off when not attached to OTC c/lung.

All that work on getting the WOB down and then you add an elastic that you have to stretch to inhale. :)

Don't be silly. That's not how the lung covers are made and you know it.

I once missed the bungy on the exhale lung.... it made a cracking SMB at the surface... exhaling was a little tricky...

let,s just say , if your moding the straps on your lungs do a good job of it , as it can kill you if you dont,
thats all i was trying to say ,

i know two divers that had no problen getting down to 65m even tho they had left 8 or 10kg of lead on the boat ,
hand over hand down the shot , lol

no shot for comming up tho , plan B

Just saying be safe ,

You can do that with the regular harness, just unthread the lungs from the harness like you did when you fitted the backplate.

I agree about the OTSCL, no idea what the fuss is about, and very good flood properties.

Shouldn't be - the lungs should be empty at the point of submerging....

Yes but the rest of the harness is a dangly clip nightmare. Just did 3 dives on it today. Lovely. Easy to get into and out of, bungee loops work a treat on a standard harness and backplate. Feels completely nailed to my back.

Falling over on the very greasy slip didn't help things. Luckily the KT baseplate took all the impact and just bent up a corner.

Don't find it a problem, if I did I'd change it. The thought of dangly-clips doesn't give me sleepless nights, however :think: I find doing-it-up brings the hard-plastic-case to my back, perhaps your harness was the wrong-size. Each to their own.

The last thing I do before submerging is blow out through my nose to empty the lungs.... That isn't possible if you has a loose one pointing at the sky, trust me on this....

The harness fitted fine. I just found it annoying. Had a spare backplate kicking about so chucked it on took about 20 mins. I really like it now, especially with a pair of KT counterlung D rings. Makes clipping stuff off a doddle. That and the HUD have made a huge difference.

Takes about 30s to take the lungs off once you have unscrewed the hoses assuming they are unthreaded from the harness like mine.
