Heard shock springs cause more pull out than regular chain, what are your experiences. Thanks

Not in my experience. All my coyote traps wear them on the stake end.

I use them too, O'Gorman has a good price

I use them they do great.

From a physics point of view I can't see how that would be true as far as causing more pull outs

tried em.
didnt like em. too much more to bed

I assume we are talking coyotes? I tried them on a 2ft.over all chain length with earth anchors. Chain would hang up on trap levers etc. I much prefer a clean swiveled short chain set up around 18" for coyotes pretty easy on their feet. As to pull outs I really do not know. I think they are beneficial on the longer chains & drags. My shock springs are sitting in a box. lol.

What?? No way!!

I wouldn't want my traps to not have them

Nope, no extra pull outs on the traps that have them. If anything they should cushion the blow on an iffy toe catch. But I consider them to one of those extra Cadillac type deals. Nice to have but you can't prove to me that they actually are worth the extra dime.
The only shock spring I ever saw that I thought was value added was those that were built into the KB traps that put the spring tension onto the levers on a lunge and tightened the jaws on a hard pull.

All good here.
Great for many reasons.

Until I trapped coyotes for the live market I didn't realize the true benefits of shock springs. Held coyotes consistently in 1.5 vic soft catch with 3 inline shocksprings on a drag. You really see the benefit of the springs on the condition of there feet.

With the quality of traps being produced today and for fur trapping is there any advantages to shock springs?

I wonder if he started using them because the traps and staking systems weren't as robust as what is available now?

The quality of a trap has nothing really to do with using shock springs. The entire point is to let the animal have give when it's trying gain momentum to yank away. Keeping the line static gives it something hard to pull against and pull out of the trap easier. It's the same as if I am holding your hand, and you try to pull it away and I move my arm towards you, you are going to have a tough time pulling from my grip. If I kept my arm and hand in one position, you could crank, torque, pry, and whatever else to get out of the grip.

So the shock spring is to help prevent pull outs and quality traps don't figure into this?? Must be way over my head...??

I use the KB, they are "built in", when I used them for cougar I put a JC inline spring 100#s, caught several when we could keep them.

I have them on 98% of my canine traps ran out and did'nt order any yet.

Good quality in-line springs, such as PITs and Connors, help prevent shoulder injuries in live market coyotes. Lessens that hard jolt when they lunge. If you have ever seen a lunging coyote in a trap with an in-line spring being worked then you will see the advantages here.

The springs also lessen the likelihood of a pullout and pulled stakes. But, if the target is coyotes, the spring needs to be the heavier wt pull rating. That strong spring will be like a straight chain if a lesser sized critter is caught such as a fox.

Now the negatives.....they get in the way when bedding if you have shorter chains. After a catch: scat and urine-soaked dirt wedges in the spring coils. When trap is re-set critters tend to dig at the in-line spring due to the odor, especially coons.

During my live market years I had springs on all footholds...about 250 traps. Since getting away from live market a few years ago and re-tooling to different type/brand/size traps, I am slowly removing them from my custom chains.
