ex. Dräger Ray

I bought a Ray and modified it into a holiday rebreather,  also I
modified a standard aluminium box to get a light heavy-duty transport box.
19.980 + 4.5 Kg.     :-)

One additional T connection allows me switching between SCCR and MCCR
Image 06 shows CCR mode with the not used tube above the big diluent bottle
Image 07 has the T connection in the diluent gas flow. O2 can be left home.
In case of typical 12 litre aluminium bottles I use config ( 07 ) without O2 parts.

As I disliked the burden of bottles weight and  weight belt in my back,
I made an epoxy integrated back plate. Very comfortable. ( 08 / 09 )
Next I "screwed" 2 weight pockets on the harness. Works fine. ( 10 / 11 )

MeRay  based on lead integrated semi rigid jacket = Great improvement !
