Minelab Equinox blue tooth test (underwater)

Some new folks to detecting may see the Equinox models are indeed waterproof, but additional headphones will be necessary to use detector with control panel submerged.

Maybe some day the technology will exist. I really do not mind the cord. What I mind is the price of another pair of headphones. I spent 500.00 on a barely used 600. A good deal. For bluetooth headphones, waterproof headphones, and a 6 inch coil.....another 500.00. It adds up quickly. I wish the gold added up that fast.

This shouldn't be surprising to anyone -- Bluetooth simply doesn't work underwater.

Correct since BT runs at 2400MHz.
It is the Carrier Frequency that is important for underwater propagation.
If you could find a TX/RX for audio that runs at a much lower frequency, below 1MHz then this would work.

Maybe the MD manufacturer should be researching this as a method for wireless underwater headphones.

Yes, I was using little BT earbuds and was searching underwater in Clearwater, FL with the Nox. Does not work when the head unit is submerged.

Will work in waist-deep water with the main head unit above water.

Outside of that, you'll need a corded headset to work with the unit submerged.
