Logosease is a pocket-sized underwater two-way ultrasound wave communicator device which enables underwater conversation. Set it at your mask strap and with simple operation, you can start conversation at once.
Words have joined to the existing underwater communication tools as slates and hand signals. You can communicate with your buddies even when you can not see them. That’s why it will give you more relief.
You can convey what you see right there – share the excitement of diving in real time, with diving words – it is your buddy who can help you in an emergency.
