Last year was my first year trapping. I used cable restraints and caught 3 greys and 3 coyotes. Location, location, location, To me this is one of the most important thing to consider. Next thing is anchoring. Last year we had a season where the ground would freeze then thaw. When the ground was frozen I would use a 1/2" by 20" steel stake with a nut welded on the top. Make sure when to leave a little bit of rod above the nut so when you drive it into the ground you don't deform the nut. Now slide your restraint on the stake. Then you slide a support on the stake made out of #9 wire. Drive the stake into the frozen ground. As the stake is being driven into the ground the friction will melt the ground ever so much. After it will refreeze in and thats all you will need to have to hold even the biggest coyote. To remove stake take a socket wrench and turn the stake by the nut. As you turn the stake, the friction will thaw the ground around the stake and it will come easily. You have to keep an eye on the weather. If it warms up you might loose your anchor. If the ground is not froze I still use the stake, but only to hold the wire support. Then I use an earth anchor to hold the restraint. I hope this helps. Good luck.
