Abstract: A small watertight electronic module is provided that wirelessly connects to a smart device, e.g., a wearable device such as a smartwatch, a Smartphone, etc., and that wirelessly connects to underwater diving equipment and/or accessories, e.g. a SCUBA tank pressure transmitter, skin temperature sensor, heart rate monitor, pressure sensor, navigation buoy, etc. The module is positioned in close proximity to the smart device and utilizes a terrestrial communications protocol, e.g., Bluetooth, WLAN, Ant+, etc. for connection thereto. In an embodiment, the module also utilizes an underwater communications protocol, e.g. VLF, ultrasonic, etc., for connection to the underwater diving equipment and/or accessories. A display is provided in certain embodiments to display information, e.g. SCUBA tank air pressure, to the user.
