I plan on bringing my collection of OTS comms to the convention in July. I have three diver units and one surface unit. If we can agree on a standard thru hull design and then everyone would just have to have the appropriate size opening to accept the pre-wired penetrator. When not using the comms a plug could close up the opening. We could dive two subs at a time and leave one unit for the standby diver/ underwater photographer.
