Please give me a call or contact us.

We are a Danish company, who have developed a new headset to be used by professional divers. The product called "Invisio Swimmer" is developed from a communications product, that is patented and have sofar only been used by Military special foces and Govermental organizations. Further references can be given by contacting our company or more information to be found on:

Since we do not have any experience or know how concerning underwater/diving communication equipment, we are seeking information on communication equipment and test divers, who would like to try out our new product for FREE.

I would be glad to receive information on underwater communication when diving professional or just as a hobby from any diver interesting in new technologies.

Please give me a call, contact our company or visit our web site (www.nextlink.to).

Thank you in advance!

u/w communication device


i was wondering if you could answer a few questions about your product. i briefly browsed through the website, but couldn't find info on u/w specs.

the majority of the members on this part of the forum are freedivers. we do not have full facial enclosures such as scuba divers, and therefor cannot transmit vocal signals to the receiver via air. obviously it would be pointless to try to communicate while holding your breath.

i do, however, could see a possible use for the device for spearfishers. although, i'd imagine it would be quite expensive.

so, i guess the most imperative questions would be what's the proximity that the devices need to be relative to eachother in order to communicate effectively? and, if the microphone is submergible, what depth is it rated to?

good luck with your product and hope to hear from you soon.
