Communication equipment

[Niazi]

Hello!
Anyone who can help me with a little detail of underwater communication equipment used by divers. Actually i have to deliver a presentation on underwater comm equipment starting from description, types, different manufacturers and specifications, etc. Anyone willing to help or tell me where i can find some good info. BTW i have very little idea about underwater communication equipment.

Are you interested solely in wireless communications used by recreational free-swimming Scuba divers or hardwire used by commercial, military, and public safety divers as well? Can you explain more about the purpose and audience?

Wireless or hardwire? How technical is the presentation? Do you need Helium speech unscrambling? Best source off the top of my head is Amron International (http://www.amronintl.com/). They do a lot of commercial and military.
