sundevil, scuba diving
, like every activity, is regulated differently in every jurisdiction. As is access to all resources, marine
or shore. At last count there were 192 nations in the UN and perhaps a few not in it, so there will be at least 192 answers to your question.
Last time I heard, in some places where there has been a lot of archaeological pillage with SCUBA gear
, like Egypt
, if you put on a tank and go in the water
without permission, you can expect be to arrested for the simple crime of using the equipment
. I haven't bothered researching that to find out if it is true.
