  • Apple Watch Ultra is impressive, but can't replace my dive watch just yet

    The issue with Apple Watch Ultra is that it has no way of connecting to a transmitter. Bluetooth is used for countless accessories but isn't feasible for underwater use because it can't reliably travel through water.

    Aqualung, Suunto, Mares, and Scubapro all use RF, while Garmin developed its own Subwave sonar system that is even more reliable. Neither of those options will work with the existing Apple Watch Ultra.

    RF stands for Radio Frequency, therefore Bluetooth is also RF. What RF bands do the named devices use that allows them to work reliably under water?

     Dive Tank Pressure Gauges use 123Khz to send the signal to the dive computer. Bluetooth is 2.4Ghz. Doesn't travel well through water.

    "Translation", "Translator" =TEXT "Interpretation" "Interpreter" = Spoken word. Important when distinguishing the capabilities of people and devices. An interpreter can tell you in your language the meaning and often nuance of the speakers words. The Translator will give you word for word translation.
