| Re: O2 convulsion Hi guys I have been doing deep CCR dives on the YBOD, and decided some time ago, following some long stories, to reduce the PPo2 down to 1.1 for any dive deeper then 60msw and longer then 15min. Plus I have buddies take NO seasickness tablets/patches as tests show these do have an effect, although they can not be specific, with high O2 over prolonged exposure. So far So Good todate !
