I'll stand by the recommendation. Plus, I'll add this. Electricity and water do not mix. Don't do it. I make a living electrofishing and managing lakes. Electricity in water is dangerous. The device in question has no safety devices, no controls for conductivity. If not professionally trained to use electrofishing equipment, don't use it. It ain't a hobby, even if someone's ponds are. A few amps in your body can't be undone. It ain't worth it.
