Farm where I used to shoot had all electric fences powered on the mains, gave a shock many times worse than battery power. I got belted twice and it REALLY hurt. Any dog affected was useless for the rest of the day.

Use a blade of grass to test the fence. The tighter you hold the grass the less of a tingle

How very true!  My technique is to sweep the floor if I can't see the screw quickly.  Surprisingly, it often works.  However there are items I've never found - even things as big as allen keys.

Back to electric shocks, in the 80s I built a pulse jet and for ignition used a mini spark plug attached to a oscillator/capacitor discharge electronic ignition/ignition coil, all mounted in a box.  The box had a momentary button that activated the sparks that could be as long as 1.5" and some 200 per second.   Pushing a button whilst trying to start the jet was a waste of a hand so i used to put the 12v battery on the button to free my hand up for pulsejet starting activities.

 

When it burst into life the first reaction is to remove the crock clip from the plug like you do for a glow (and not remove the battery off from the button).

 

That wakes you up!!!!!  

 

Must have done that dozens of times!
