PASSING GAS BELOW 20 FEET WITH A RGU

WARNING

This is another 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. Pure oxygen rebreathers are probably safer than fully closed circuit rebreathers as long as you stay in 20 feet of water or less. Throwing caution to the wind, having lived at least 80 some percent of my life, I decided to increase the depth. This means adding some diluent to the oxygen to keep the partial pressure of oxyten within a reasonalble range. I already had the sensor system. If you don't know what a reasonable range is---get out now---go take a course---take up something safe like testing grenades in your garage. You ain't ready for this.

The componants of this modification include:

A six cubic foot pony bottle.

A first stage regulator.

Scubapro Air Two Regulator. .

Adaptor for the air inlet and oxygen sensors.

Tank holder addition for the RGU.

Enlarged Counterlung



In another project, I replaced the counterlungof the RGU with a more functional larger one with much better color for sport diving. The bright colors make it easier to find find the body. One of the advantages this replacement is that there was a built in port for an inflation hose and inflator mechanism that can be replaced with an Scubapro Air II.. Ninteen years ago, I bought three of the vests for a family trip to Hawaii. Fourteen years ago this same vest had been modified to make a BC for my nine year old son Patrick. Talk about a packrat--talk about recycling--I am the King.
