Had some say they got the neoprene counterlungs for that very reason. I have a pair but haven't tried them yet so I can't say but they are definitley smaller and more streamlined.

Also of note is that they were the first counterlungs to be used on the Meg and are the type chosen for the Cis Mk16.

I believe there are pros and cons no matter what configuration you use.

Let us know what you think of the neoprene when you do try them. Leon suggested I give the neoprene a try which I'm going to do as soon as I can.

I like the shape and size of the neoprene CL's, but they are more boyant and not as tough as the standard ones. If Leon decided to make CL's with the same shape as the Neoprene version but in the nylon fabric I will place an order

So back on topic now...

Thanks for the Pm,

I have just got rid of a pair of Neo lungs I only used them 3 times and found that the ADV was to active and called me to isolate it more than I like, not to mention the ease of a puncture. I have done over 700 hrs on my existing lungs with no problems, its just added weight for travel I’m looking to get rid as I have used and recommended the ankle weights as they fit great in the pocket at the rear, but an extra 2kg just for that is a pain in the ***.

After reading through this thread, I wanted to give my opinion, which is that even though it appears to be a pretty logical and intuitive procedure, and after all, only takes a sewing machine and thread, I would recommend against sewing your own counterlungs, without taking one step first. What seems to be a very simple process, can easily cause some very negative breathing characteristics and counsequences underwater, if overdone, or not applied in the right areas. Instead, I would make a friendly recommendation that anyone considering doing so should contact ISC first. They have a lot of experience in this area.

Be safe,

Jim

Just an idea, but being new to Megs, not sure if its a good one.

What if a heavy duty plastic Zip was stitched down one side of the counter lugs( say the inside edge), then you can zip the two halfs together and adjust by how far you run the zip down the length of the lung.would this would have the effect of pulling the two halfs together and adjusting the internal vol.
Or even use a short zip length either at the top, or bottom.

Good or bad idea.?

I basically glued strips of velcro onto the inside edges of the counterlungs. Once the velcro is stuck together, I have reduced the volume of the counterlungs, but can pull them apart underwater if I have any issues.

It's also a non-permanent change, as I can take off the velcro at any point.

Interesting -- did you use glue and velcro or that industrial strenght velcro with glue on the back? how does it hold up in the cold water?

I decided to try blackwitch to glue the velcro down. I wanted something that remained flexible (doesn;t go hard like aquasure) and was removeable. It's messy as hell to use, but seems to hold fast. Going to be in Scapa in 2 weeks time, so I'll give it a proper work out then, and see how it holds up in cold water.

so I finally had the chance to make a handful of dives on my new stitched meg lungs and they work a treat, I am now able to archive good horizontal trim without any additional top weight and still the tanks in standard configuration (valves down).

I had them stitched on th inner sides and its reduces the total volume but not that it creates me an issue for lung volume even working very hard. Great job ISC.

As an update - the velcroed CLs have done a few cold water dives now. Worked a treat and the velcro is holding fast
