Having seen the semi closed rebreather Rick Stanton used to push the end of Cocklebiddy and after some conversations with John Volanthen about small rebreathers he agreed to loan me a small 1kg scrubber he’d had made – complete with male p-port. I purchased a CDBA mouthpiece from a diver on Rebreather World, an extra p-port from Tecme, an MSR water bag and away I went – armed with some other bits left over from the first rebreather I built – my chest mounted “silent green”. 

The results are below, the whole rig is nice and compact and I’ve done several excellent test dives on it. The plan is that I’ll use this in Culimebro this summer.
