Does anyone know how to rig up a device that works like an old timey telephone that can shock fish up? I know TP&W uses them to survey fish populations in lakes and I need to do the same in my pond. Fish truck is coming in two weeks. Thanks in advance, an oh yeah, I am serious.

You can get a pretty decent rig right off the shelf...

Or there is a somewhat crude device you can build...

Usually best to hire it done by a fisheries biologist.

Thanks so much. At 3/4 of an acre, a biologist is just not in the budget.

Lots of magnetos on eBay
