BMCL good or bad

jkaterenchuk · 5th February 2008, 14:29

I have read the posts on BMCL and am still undecided if I would want to make this change. To help me make a decision I would be interested in hearing from those that have actually made the change.

1) What are the good and bad points with the new config? Aside from the clear chest area what new issues came up as a result.
2) What method did you use to convert? Buy one of the kits...do it yourself?
3) Was the extra cost worth it?
4) Would you do it again?

I would never dive a OTS-CL unit. Have used the same BMCL on YBOD, Meg and soon Pelagian units.

Good points:

Clean chest
Easier to kit on/off
More protected when diving around sharp or abrasive objects
Same WOB - if using the right BMCL design
Easier to customize for MLV

Bad points:

Everyone wants to steal mine

DT BMCL system.

3) Was the extra cost worth it?

Yes, most definitely.

Quote:

4) Would you do it again?

Yes, most definitely. Would NOT dive YBOD/Meg/Pelagian without one.

I've a better fealing of the gas in the loops. Easier to stay trimmed. I can open my dry suit valve without problem ;-))
Bad points: You have to buy some extra to be able to put off board diluyent. Either Narket at 90 sistem or something with swagelock. You don't have a push botton to inject diluyent but you can do it with the ADV. (easy enaught)

I bought the kit from Paul Channing. I spend lot of time thinking about the way to do it and at least this was the way.

3) Was the extra cost worth it?

Absolutely

4) Would you do it again?

Yes, and i recommend it. This way the inspo is a fantastick rig. Always, and if you thing about it will see, people complain about the couterlung position :-<

My 2 cents

Why not ?

Pelagian comes with HUGE OTS-CL system that tucks under my arm pit so not difference than the YBOD/Meg OTS-CL systems.

I sent the Pelagian lid to Bruce to fit the Pursuit since it already came with HUD. I will pick it up sometimes in March when I come to the US, then try it out in the Red Sea one week-end.

I like BMCL
I was wondering HOW you are doing it.
I am thinking of trading in my Sk for either a Pelagian or a travel rEvo.
Thanks

1) I'm sure a proper breathing machine can detect some kind of change in the WOB. However I can't. The way I have it set up, the ends of the counterlungs are comming over the shoulders and the T-piece is sitting in it's original position.
The balance of the rig has improved a lot. The inherent unstability with having lift placed below you and negative bouyancy above you are a thing of the past. You are now far more stable.
However it now requires a bit more effort positioning yourself in odd angles.

I had a chance to test the watertrap that John Routhly made on the O2 add, it works just as well as the original one. On a hardworking dive I had a leak in the mouthpiece, about 2½ liter of water ended up in the exhale counterlung. About one cupfull made it towards the bottom of the scrubber.

2) Paul Channing BMCL kit, brilliantly made.

3) Absolutly

4) I would not dive any OTS rig again. It feels good to be free.

Sorry that I wasn't clear on the last post.

I will be diving the Pelagian with the DT BMCL system, same as how I dive the YBOD and Meg units with.

I have it configured so I could pick up the same BMCL and install on any of the 3 units without changing anything.

No can do for 2 reasons:

Sea containers are still with Egyptian Customs for 3rd week now. The ba$tard$ have opened every single box in 1 x 40cf and 1 x 20cf containers, then determined that I must pay 3000% import duties since I have "too much dive gears" so must be a professional
Can't show pics of DT BMCL system, it is DT's baby.

But it is simple enough to explain... Just make 2 additional hoses (per unit) to connect from the lid of each unit to the CL. The hose connection on the lid is specific to the unit, the other end is same as on CL.
