Hello Gabor.
-> I heard about an electronic device, wich generates electrical or
-> magnetical field/frequency somehow around the diver (applicated next
-> to the airtank), wich scares away any shark, wich gets too close to
-> you while diving. Is this a true news, or just junk? If it's true,
-> can it be purchased somewhere?How does they work (I hope it will not
-> hurt by any means phisically the animal)Thx, bye:
I can tell you that the device does indeed exist and it has been said to
work very well, however I do not know for sure how well it actually
works (if at all).  I am sure there will be a lot of talk  about it just
keep your eye out for it.  The only thing I can confirm for sure is that
it does exist and is "said to" work.
Hope that helps you out.
Type to you later
