I question the need for some of these super powerful traps. I have 4 coiled some of my #2 Bridger dogless but to be honest, I have never lost a Yote in a 2 coil #2. Beefing up a 1 1/5 or 1.75 I can see but these 2 & 3's seems like over kill.

I 4 coiled some of my MB 550's and now find them harder to set than my MB 650's. I too have never had a problem with them holding even the nastiest coyote but do like the extra power for dealing with frozen ground. If your not dealing with weather extremes then I personally don't see the need to have them 4 coiled.

Need to couple the springs with laminations. Really can't do one or the other. Weak springs can allow side to side movement in the trap resulting in cuts

I only four coil after years of service on a trap and the original springs lost some of there strength. I use only Bridger and MB Coilsprings and two coil always were enough for me. I think the ones I started turning to 4 coils I had purchased while I live in the UP which was around 15 years ago. You would be surprised over 20 years how many get stolen, run over, etc,.

What about places that have 0 fox ? Why not have a powerful trap? A powerful trap can break threw mud ,snow, and some frozen stuff and catch a coyote. I use mostly MB 550s BUT see the need for powerful traps

In my opinion 4-coiling is not needed until the original springs become weak. I have some four coiled bridger #3s, bought them that way, and I have held antelope and deer in them, I don’t like that. My two coiled mb550s haven’t met a coyote they can’t hold in ten years of use. Around here there’s always a chance you could catch a lion, and I’ll tell you what I want that sucker gone when I check because the law says I have to release them (thanks hound hunters)

Center located swivel helps with the trap sliding back and forth, along with laminated jaws. Shock springs also cut down on damage and plenty of swivels. Four coiling doesn’t seem to make much difference other than holding critters I don’t want to hold.

4 coil is flat out faster.
Fast traps mean less toe catches and misses

I don’t believe that one bit. Pan tension has way more to do with it than speed. Even my slowest traps are way faster than a coyotes reaction time. Does anyone really think that a coyote can process and react in the amount of time it takes from the dog releasing to the jaws being closed? No way. It doesn’t even know something is wrong until the jaws are shut.

To each their own

I thought the point of 4 coils was to bust up through crusty snow or ice? I'm s newbie and that's just what I've read.

I own only a few 4 coil traps that i picked up cheap at a flea market. I use them ONLY on beaver here in PA

4 coil beds better with my bedding system. I bed with a hole under my trap. Sorta like Zaggmans, but my hole in the ground looks more like an egg because I have a loose jaw trap. The extra springs just give me a little more to hang on the edge of the hole.
Do I need the extra power on a new trap? No I don't.
But I need it. Hope this helps.

I was also referring to some of the super heavy frames of these traps. To me it is like the guys that buy a 1 ton diesel dually PU to pull a single axle trailer.

Ok this might be off but here is my take on this ,
The only reason for lamination is because of 4 coils.
The reason for 4 coils is because of lamination.
Now that said a trap with proper jaw lock up needs no 4 coil unless its laminated ,because the trap once laminated produces a wider surface. Which in turn produces less pressure on the foot.
Lock up is everything.
For real freeze thaw conditions , 4 coils will help break the the crust , but if the pan can not go down the trap will not go off.
The only reason to use 4 coils is poor lock up, of winter time conditions imo. Square jaw type trap have are not as fast to break cover imo and do not lock up as well imo.
Merry Christmas everyone.

A frozen trap is a frozen trap, doesn’t matter how many springs it has. It doesn’t take much ice at all to hold open a 4 coiled trap. I just pulled some 4 coiled Bridger #3s and some 2 coiled mb550s and none of them would fire with a skiff of crusty snow on top.

That's what I was thinking so to speak. I was also referring to the super heavy frames too. They are good as drowners but if you have to hump them all over dry land they get heavy. Like I said, I have never lost a MN Yote on a Bridger 2x2 # 2

Do the music wire springs for somewhere between stock two coiled traps and four coiled traps?

If it takes a hammer and chisel to get a trap out of baked SOWEGA red clay, I don’t care if it has 6 coils, it ain’t gonna fire. I’ll stick with the 2 coil MB550’s. They’ve held every K9 that’s stepped in them, even if just a toe.

I don’t think 4 coils add much holding power. The holding power is more determined by the levers. I believe 4 coils gives you more power when the trap is fired. So if you have frozen ground, 4 coiled will break through faster and easier. Or if you have heavier and thicker jaws from laminations.

I think high levers are the key to holding power. I grew up about 30 mi .north of Bernie Barringer. He is just So. Of the IA / MN border. He likes the high lever theory. His book "Farmland Trapping " is a very good read. He compare's B&L, Monty's .....
