Pigs are far and few between here, but we have a few. I haven't caught any yet, but I did build a portable rotisserie, and these anchors to tether my 'yote traps. Might work for pigs. These anchors I make, will not pull out with #300 pull straight up, when sunk 1' deep. Should hold more when pulling sideways.
I used a #300 game scale to test, and maxed it out before retrieving my anchor with a comealong.

An unemployed Jester, is nobody's Fool.

the only real difference between a good tracker and a bad tracker, is observation. all the same data is present for both. The rest, is understanding what you're seeing.
