Hi,

Ive used/taught a few CCR units over the years but tended to lean towards OC as it is more forgiving during the type of stuff i do. Im sure if id have caved more then i would have bought some kind of box to benefit from their relative cost effectiveness. If im working im not paying for gas and need the predictability that OC provides especially with unpredictable customers. Ive occasionally used boxes for fun but one didnt really stand out above the rest as i have developed special filters that reject the marketing 'claims' of manufacturers

I like the Pelagian for its size and it seems as capable as i need it to be. I havent seen any ECCR units that i would strap to my back for deeper dives. maybe if someone gave me a gold plated twin-boris i would like that too

I still like the odd deep dive and sometimes my mind is elsewhere and ive no established faith in electronics at the moment neither have i made my mind up about scrubbers in deep water either. The manual add system of the Pelagian seems to work fine if you use the correct first stages and i like the low profile lungs too - it feels only marginally bulkier than my existing OC harness.

I have incorporated my Pelagian into my twinset for deeper dives, this gives me both my faith in OC kit in deep water and plenty of bail-out if the rebreather has a hiccup. Ive learned over the years to take plenty because I still cant breathe the water yet despite nearly having to several times when i was a little too optimistic

hope that answers your questions
