anybody knows where could be a good area to organize a potential trip to Portugal with some deep dives in reach? experienced group looking for wrecks down to 100m.
i found Algarve but all the infos are about shallow wrecks around 30m.
thanks :)
hi everybody!
I’d like to learn more about the system used to get the helium percentage using just 2 oxygen sensors and no helium analyzers at all, in this mixing stick i’m using at the moment for the blending.
I couldn’t find much on their website...
Anybody can give me a full explaination...
