For the life of me im having troubles visualizing how the dog knot system works. I cant see how that small lump is going to hold a yote! Or is the long chain the key to it all similar to portable pockets? I had a coyote hound that could pump a 24" rebar stake on 20' of chain! It was constantly jumping getting a wave action in the chain.i'd love to find a easier alternative to cable stakes for mid season relocation! Im wore slick after pulling 100 wolf fang anchors
Larry makes a great point . . . and not to beat a dead horse, but the genius of the stake was that if you drove the stake in the ground and then pulled it out (i.e. you didn't make a catch), the stake usually comes out fairly easily. However, if you make a catch, the animal circling the stake drags dirt and small rocks down into the stake hole where they land on top of the "knot." it then acts like a disposable and its very hard to get out. Like Larry says, many a time I've seen a coyote with the stake half out of the ground but still well held because he'd tamped so much dirt and rock down on the knot that the stake wasn't coming out.
Also, on the long chain, the G men had that huge swivel, heavy chain and long chain for several reasons. One of them was that it helped pump the stake out of the ground without tools. If you hold the trap in one hand and "whip" the chain toward the stake, that 3 feet of chain will most times pop that stake right out of the ground.
While every staking system has its pros and cons, the old government 3N with a long, heavy chain, heavy swivels and a dog knot stake had a lot of advantages and stood the test of time for tens of thousands of coyotes.
