Varmint Buster Zapper

Anyone seen or used this before? Supposedly you can put on your feeder and it will shock varmints(coons). Not sure how you would keep from shocking all animals.
Found at Academy, I'll post a pic as soon as my computer lets me

I won one as a door prize about 2 yrs ago. The metal wire ring cage that protects the spinner plate has rusted/corroded up pretty bad. Not sure how much longer it will last though. Won't find out since the timer crapped out.

So it outlasted your guard? Is it still working- keep coons from hanging on the spinner cage

how does it impact battery life?

When the timer quit working I have not used it since.

From what I remember about them they are low voltage(similar voltage to land line phone) and do not impact battery much at all.

Thanks
