Because the bioelectric field created by the animal's heartbeat carries only over short distances, the shark's electroreception is effective only for finding objects that are very close to the shark's head.

Hi rube,
sharks can't find metals or discriminate between. To detect an electric field it must be present...to detect a current flow it must be present.
When an iron/metal boat is in water...electric field could take place by water/boat interaction--> electrization could be present...but all the rest e.g. a buried gold item how could produce such an electric field ? Sorrounded by the ground matrix ??? Not insulated I mean. You know that insulation occours in nerves...so animals are different from perfect conductors like metals...
Don't understand how a shark could find e.g. a gold coin...so this is another fake issue.
So all this stuff...e.g. connecting a battery pole to something...then expencting some detection IS NOT a simulation of what really happens few cm underground for a metal. So, means nothing that someone could detect a battery to metal connected say a mile away...at least for our purposes.
Best regards,
Max
