Underwater Communications Applications :
Wireless underwater communications uses water to carry an acoustic signal from one transceiver to another, much like the way dolphins use sonar to communicate -the rest is magic (or, technology). Underwater acoustic hydrophones are battery operated, push-to-talk, and with ranges that can reach up to 10,000 meters! We offer many features underwater acoustic transducers such as multiple channels, frequencies, and menus, with options such as volume control to enhance the experience. Similar to a two way radio, simply push your push-to-talk button, say what you want to say, release the button and communication is underway.
