Hi Mark,

Thanks for making your lists public.

I am curious that your pre-dive checklist does not include a check on the correct operation of the DSV one-way valves. If checking of loop integrity by way of negative and positive pressure tests is warranted, shouldn't verification of correct gas flow direction also be checked?

This check also appears to be missing from the Diverite "Survival" pre-dive checklist.

Regards,
Tony
