REPLACING THE COUNTERLUNG OF THE RGU

WARNING

This is a damn fool project. No one in their right mind would do this. If you repeat this you are a fool and will probably die using your creation, leaving some very unhappy loved ones. I did this just for the experience and to solve the technical problems. Everyone that I talk with says this unit is a piece of junk and should not be used as a life support system. Experimental life systems can be deadly. You have been warned. I will probably use the grown up version a couple of times, take some pictures and take the thing apart.

Lets face facts. Unless you are a Dave Sutton type who will dive stuff that has that GI Ivan look, you can't be serious about taking a RGU out in public. Not only is the color terrible, but there is one real flaw. The counterlung is a tad small. My solution was to dig out an old snorkle vest and replace the RGU vest. This gave me several advantages.

It has more volume.

The color is much more fun.

It had an oral inflator for the oxygen sensors and diluent inlet.
