All valid points, the reason we are doing this is because we have received feedback that Homebuilders are being denied the possibility to travel and dive their units from centres that ask for proof of certification or of relevant training for certain dives.

My experience of most self-builders is, that whilst they are completely bonkers , they do, on the whole have a reasonable grasp of what they are doing and Phil and I, with our experience, should have a decent grasp of what should be included in a homebuild CCR.

If someone turns up with a unit with no oxygen monitoring with at least 2 cells, we ain't going diving, same for someone without an ADV and no manual diluent add, extreme examples but nevertheless important to know .

This is not being forced upon anyone, if they see a need for it, and market dynamics have already demonstrated that to us, then given our location within Europe, outside of the EU and it's sometime 'Nanny-State' regulations, then we are happy, as divers and as a business, to assist.
