I'm not even going to ask their price. I can see its too expensive.
Anybody
know how to make one of these?

The classic fish shocker was a hand-cranked telephone ring generator.
Puts out ~100 volts at ~20Hz when cranked. They were a very common
military surplus item, having been used for field phones. I recall
seeing one advertised in the last year, although I was not looking.

Talking of mil-surplus, my father and his fellow squaddies in the UK Royal
Engineers used to fish in Ireland during WW2 using gun-cotton. He was there
looking after the mustard gas (which of course we didn't have), he also
trained special forces in demolition. Apparently, a standard slab of
gun-cotton (about the size of a paperback book) left hanging in the flue of
the stoves used in the army huts was the usual way of showing one's
displeasure with the occupants.
