"Calling fish" is called "monkeying" by people that equate cranking the old generators to an organ grinder and his monkey.

The more modern method uses a re-rigged heart pacemaker and 12 volt battery.

The very small pacemaker rigs are easy to hide and there are plenty of reasons to have batteries.Poachers don't even have to crank the new monkey rigs.

Does a pacemaker use a diode cascade?
