Would an MB550 be large enough for coyotes, or would the 650 better fit the bill?
Looking to replace some older traps next year.
Using #3 Bridgers, Victors and older Herters traps at present.

In my opinion the 650 Is over kill.

My 550’s work just fine. But that’s as large as I can go legally.

The Bridger #2 or #3 dogless is a good alternative and frankly, the lower cost allows you to buy more traps. I have never had a problem with them even when they have had to hold an inadvertly caught wolf. I guess it depends on what label you need to see on the back of your jeans.

The 550’s are a perfect all around trap.

I'm with the largest legal crowd.I ran 650's for a while and switched to the no bs k9 extremes.I could not be happier, they are built better than any trap I have seen.Everyone raves about the Jake traps but the extremes are just as good.They have a huge kill area,the pan sets below the jaws when set and bed wonderfully.They are twice the trap of the 650 and the 550 (I own both).If you are a small dirt hole guy and want small traps go with the extreme jr. I use a 3" hole that gets bigger after remakes and for blind trail sets and flat sets the K9 extreme gets the job done better than anything I've found.

Love my 550s. Best coyote trap. Love they come night latched

Thanks to all for your input!
Much appreciated!

Man those 650s are known for a bad dead spot on the pan, I had some and was always jacking with them trying to get the tension to stay right. If you are after a dogless trap as stated above the k9 extremes are really nice, as well as the jakes. I have both and they work really good for me. I also have some k9 juniors and really like them too. If you get some of them 4 coiled though you will want to use some wax on the pan catch to get the tension lower. The 4 coiled ones I had were probably 5 lbs or a little higher on a floppy pan. I have some 2 coiled ones now and the coils are on the loose jaw side and they set right around 3 lbs on a floppy pan. I have not tried any of the dogless bridgers, but they look to be a well designed trap at a really good price. If I changed one thing on them I would make the pan catch below the top of the jaw like the extremes, and the jakes, just personal preference I sure the work really well the way they are set up.

For a 24 hr. Check any of them will do alright.

Little adjustment on nut holding pan to increase pan tension and I have had nothing but high pad catches. I am a financial conservative (cheap) and have no need for what is most popular

As stated above maintaining pan tension on the 650's is an exercise in futility.I have adjusted pan tension,added a washer to the dog/jaw holder to take out end play and they can be 4 lbs today and 2 up to 10 lbs tomorrow. I am as big a financial conservative as there is but I am positive my son will be setting and using the K9 extremes 25 years from now or longer
If I prorated that out the Extremes are very financially consciousness.

I bought a dozen 650 this year and set them on the coyote and bobcat line and can’t say enough good about them some of them have had a couple coyotes in them with no broken or damaged part and also love the low profile

I've caught a dozen or so yotes on my MB450s so I'd say the 550s would be perfect. Thinking of purchasing a 1/2 doz. 550s or Extreme (Jr?) for next year though to try something a little bigger for yotes & cats.

I use mostly 550s and have caught everything from possum to bobcat in them and every in between. I like the size and how easy they bed. I use only 2 coil also. They are great traps. Never had to straighten a trap out after a catch since I switched.

I’ve caught a slug of coyotes in the 550. You get a bent dog on them every once in a while but they are a strong little trap. I prefer a dog-less #3 trap anymore.

I’ve got some 650’s also but don’t use them much. I should sell them.

If a coyote steps In a #2 duke square jaw he's yours.

HIT THE NAIL ON THE HEAD RIGHT HERE!! Plus they come right out of the box dipped and ready to go and that coating will last a couple of years. Financially conservative, yeah what ever, I'm always out of money and if I made more I'd still be out of money, hahaha. Tell ya what, take the cost of a dozen mb 650s, add the cost of your preferred treatment and your time/labor to treat them and I'll bet they come out to close to the same price as the k9 extremes, but you still might have to tinker with the pan tension, hehehe

They are actually very good due to the lock up and physical weight they allow very little to no foot movement. I am convinced that foot movement causes the most damage

Love the K-9 extremes I have. I use the 4 coil and do have to wax them but high foot catch on mine this fall. They were not going anywhere.
