[Logosease] is an underwater two-way ultrasound wave communicator device, with which you can enjoy conversation in scuba diving. Just set a pocket-sized Logosease at diving mask of each diver, you can use it easily even with the air regulator in your mouth.
Not only for the advanced divers diving all year around, but for beginners who take diving course in diving school, and tourists who experience diving in resorts, we provide the new joy of sharing discoveries and excitements underwater with [Logosease].
Communication is done with ultrasound. Bone-conduction microphone (built-in) collects the vibration of sender's voice from his/her bone, and send it via ultrasound. After a receiver catches it, the bone-conduction speaker (built-in) will transfer to the receiver via his/her bone.
