Leave them set or or unset

I have had the same question. But I leave them unset as that's how they are when purchased.
Plus this sounds stupid but I think that leaving them set might give them a reversed memory as they are spose to be open when they go off but I'm probably wrong..

doesnt matter.
The only times my trap springs are not set is when an animal is in the trap.

Supposedly doesn't matter. But I was taught as a kid to always store them with springs relaxed (unset) so that is what I do.

I leave them set and I see no loss of spring strength. And they are way easier to store when they are set.

Either way with me. Depends on how I put them away

Mechanically speaking, if the springs have been designed correctly it won't matter. The material stress when set should be below the fatigue stress of the steel. That being said, being relaxed is the second lowerest stress on the spring. So it gets down to what's your preference.

This seems to come up every now and then, the longer one should’ve been moved to the archives…….maybe it is?
You damage your springs by working them. Mine are all set. If it’s empty but set off, I reset it because eventually I’ll have to set it again.
Extreme temperatures seem to do funny things to springs sometimes. I’m not talking like oven heat, but +40 to -40 or more.
Hopefully a spring manufacturer might see this again and comment.
Each to their own, I set mine.

Set, easier to store and ready to go when I grab them in the fall.

I see several of you saying they are easier to store with springs set? That is probably one of the reasons I continue to store them unset, I find them easier to store unset, with springs folded in, so they are a nice square without springs flopping willy-nilly.

Yup, this^^^^

Always decompressed when not in use. Something causes springs to weaken, and the only explanation is its from them being compressed. I have bodygrips I've used for years and years and theyre nearly as strong as they were when I bought them.

I store mine set, can't stand it when the safety's hook on to everything.
Also first after I buy any coni-bears I cut the chains off.
And use cable for tie offs.

Same here. There's always stuff on traps that'll hook, the dog is probably the worst on a Belisle. A guy could pinch it tighter so it's not so loose on the jaw, but I don't screw with it. When stored, they're not flopping around, they're in a milk crate or something. 330's are wrapped with the cable tie off that's connected in the eye loop. The 330's don't get much rest though, they're getting use year round.

Mine stay set, wire the springs together with the trigger between them .
