Wireless connection - under water?

NOW this would be a game changer: IF the wireless connection will remain communication when the control box is submerged.

Both the ATMAX with the Z-Lynk and the CTX3030 loose connection between the control box and the headphones when the box is submerged.
The ATPro with the Z-Lynk system is not submersible.
The Deus has a wire aerial antenna kit to bring the signal up from the coil to the control box, but the waterproof headphones are still attached to the control box via a wire. Really...not wireless headphones.

Any of you tester --- comments please.

Unless Minelab has found a way to violate the laws of physics, there's absolutely no way a bluetooth frequency/device can penetrate any distance in/under water.
(Especially seawater.)

Laws (physics and otherwise) are made to be broken (see faster than light and sky hooks). Okay not yet, but we still try to figure it out and the one who does wins! :beers:

+ that thing where they can slow down the speed of a light beam.

Lower radio frequency's will travel through salt water i believe. Higher freqs don't cos the conductive salt water absorbes much of the signal.

Yes, ELF (extremely low frequency) frequencies can...but the transmitters and antennas are huge...as are the power requirements.
That's how submarines communicate.

See Wiki article here:
https://en.wikipedia.org/wiki/Extremely_low_frequency

A good rule of thumb is that the 2.4gHz band...in salt water...gets attenuated by about 200 db/meter. (In other words, it kills it off dead immediately.)
Underwater communication normally requires very low frequencies (10 to 30 kHz) (where attenuation is in the order of 3.5 to 5 dB per meter) and lots of of power.
