Excessive counterlung volume on my MEG

depth · 11th July 2007, 08:40

Hi Rebreather World

When i bought my meg I thought "wow, these cordura counterlung are huge for me". I am only 174cm and weigh approx. 65kg (US: five foot seven and 143lb).
Even after diving the unit more than 40 hours (minimum volume), I still find the lungs excessively big, and come to realise that i never will be happy with them and dream of replacing them with custom ones.

I measured my own lung volume by blowing in to a bag and sinking it in a bucket of water to see how much water i displaces, and it came out to about 4.8l. I measured each Meg counterlung to be 4.5l.

What is the optimal counterlung volume for me?
Has anyone successfully modified the supplied cordura counterlungs?
Are there any other sollutions?

Safe diving

Christian

Trade them for a pair of neoprene Meg CL perhaps ?

I have a pair of neoprene Meg CL that I don't use, but I am hanging on to them so when I sell my Meg, it will be complete.

But I am wondering which is more attractive to the globally average Meg user who are not required the neoprene for added warmth (like you), cordura or neoprene?

If cordura, then I might be interested in a trade.

Hi Christian

My CL's seemed huge also, but after having ISC sew the inside seam down it was less noticable. It gives a streamline look for the front and it gives optimal volume for me. It is another option, plus I am to rough on things to have neoprene CL's

I will consider this..... But, I will most likely say no, because the Neoprene ones are less tolerant for abuse!

Ill let you know....

This sounds like a usable solution. Like gtzavelas, I would appreciate if you could post some pictures.
Any idea what the Volume of the modified lungs are?

Thanks, but that wasn't an offer to trade (yet)...

I was polling to see which CL material people in general tend to prefer to increase my chances of selling the unit later on...

Both. Neoprene for deep, long, or scooter dives, and cordura for when travelling abroad and you don't want to worry about punctures or pinhole leaks developing during transit, especially when weight and space (i.e., tight packing) are an issue. All that being said and FWIW, the crushed neoprene is pretty robust.

Yes, the set I got came with the Smithers electronic but still in great shape. And I know Ron dived the sh*t out of them too...
