I don't use shocksprings myself but have been toying with the idea of using some.But can't really see the advantage over what I'm using now.I'm running 12" of chain,nail swivel,3 links of #3 chain,nail swivel,3 links chain,nail swivel,then 3 more links of chain,then a quick link to cable stake.I drive the cable stake in the ground until the end swivel is below ground.Then give it a yank to set the stake and my end chain swivel is above ground and the last 3 links are below.I have the 12" of chain above ground.I've held the occasional toes catches nicely even a back foot 2 toe catch,of course the traps are fully modified and offset.There is definately a noticable catch circle from scratching and pulling.Most coyotes are laying down when I show up and pretty much don't move when I approach.I can't see where they could get a really good lunge on that setup,they really only have 2 feet of run way.I'm wondering if adding a shockspring is going to improve anything on this setup,and if I add a spring should I lengthen the chain out.My only reason for thinking about adding a longer chain and spring is badgers,the spring for the coyote and the length for the badgers,I usually average 3-4 badgers a years and release them.But using cable stakes these last couple years,and the way badgers are at digging,I had one that after releasing him out of the hole he dug under the stake,the stake just slid out like it was butter,the only thing keeping him there,in my mind,was daylight keeping him in the hole while the cable and chain was like looped over solid ground that was not dug and he was tucked under it.Here's a pic of my chain setup.

Here is said badger.

Most that I catch end up like this with dirt mounded up to the base of the trap.

So what are some opinions,should I go longer and springs or stick with what I'm using.My setup works well for coyotes but those badgers woory me some,there protected here and don't need one running around with a trap on its foot.Over the years I think I've only had 3 dig under with the short chains,all the rest were mounded.Will lengthening the chain cause them to dig a hole more often and go under but not under the stake,or make no difference.
