My dives seem to be getting longer and longer. I am on open circuit and having a problem with the CNS clock. I found this paper and was wondering what some others are doing for their dive planning and maximum OTU's for a single dive on a fresh diver. I have been told to try and keep the OTU's for a single dive below 300 but according to this paper "It had been observed that an
operationally acceptable daily exposure for a “fresh” diver
was 850 OTUs." What are others doing?
