There are several regulations to using cable restraints.
Can not be set where the animal can reach Rooted woody vegetation greater than a 1/2" or any part of a fence or any other immovable object that can cause entaglement.
Can not place them closer than 25 feet of sight exposed bait.
You need to use a specifically made cable restraint for WI. regulations with the correct stops, breakaways, slide/washer, and cable length and diameter.
They work ok, but our equipment regulations are prohibitive to catching great numbers of yotes in them. You will need a catch pole also in case you get a non target animal and need to release it. A piece of 4'x4' with some slots at the top for handles and the corners rounded is nice to have as a block for releasing animals.
I know I jumped the gun on the carcass thing on public land. People get confused quick though when it comes to the regs. Did not want anyone to start thinking they could bait the on public. Although I do wonder about it. Since I have heard of people getting tickets for dumping fish parts on their land.
Yes, those snares would be illegal in WI. Would still have to follow the laws on their use on your own land. Although you could dispatch nuisance animals on your land without a license. A trapping license does allow for you to dispatch a caught critter.
Minnesota trap products has a book cheap. Think it is called guide to snaring. Also sell the WI legal snares. Just like the snare shop.
Really though the regs make it a pain in the butt!! Some of the best locations are illegal due to the entanglement thing.
I'm with Droptine. Legholds are normally more effective in this state. hard to beat a good dirt hole set. Either way it will not be instant success. It is going to take some time to get it down.
