Tom you are so right, but do you need to spend thousands to be able to say a few words??? My device is now being used by Underwater Astronaut Trainers. Also many professionals. Something Mario does not understand is big price does NOT mean better. Also I did not start this thread for advertising but to get a feel for what people are looking for. I have used high dollar com units and believe for Commercial diving it is needed but not for speaking "are you OK, look at that eel, hey dive buddy look..." This is what we offer and will have a $10,000.00 challange at DEMA in New Orleans this year. NO we have not spent a million on advertising yet but that is comming this year for 2001. As I have said many times this is for the true Sport Diver who loves to dive and share what they see with a true friend or partner. Why wait till shore and who really dives side by side and able to HEAR or see hand signals. Oh yeah I can blast my SUB DUCK and wake up everthing in a 50 feet area. Thank's again and hope to see you all at DEMA. If you don't believe put up 10,000.00 and take the challange we will. I really enjoy the imput everyone is saying and it is helping us find out what real divers really want...J.P>
