I've recently started my application process to join the Navy as a Warfare Officer with the idea of specializing as a Clearance Diving Officer once qualified. There were a couple of questions I wanted to ask and if anyone had information about them I would greatly appreciate the replies. - Is it possible to solely specialize in clearance diving provided I passed my Basic and Professional training? - How long is the MCDO course and is it possible to be stationed at a shore based dive team once qualified? - How long is the time period at sea during professional training i.e. will it be months at sea or will ships continue to return to port? - How easy is it to contact friends and family once on board ships? I apologize for all the question and will appreciate the responses.
