Mysterious Baltic Sea Object Disables ALL Electronic Equipment

Very strange object! 

The strange tale of the 200-diameter wide  circular object discovered last year on the  floor of the Baltic Sea gets curiouser and  curiouser, with guesses as to its purpose  ranging from a crashed UFO to a Cold War  submarine base.   Described as shaped like "a huge mushroom"  and rising 13 feet off the sea floor, recent dives  by the professional Swedish Ocean X Team have  revealed several other strange features - and "ALL"  of their electronic equipment was repeatedly  disabled as they swam directly over it.     Video: Mysterious Baltic Sea Object Disables ALL Electronic Equipment
