I used some Duke 650's this season, and like them as well. They bed like a dream, but yes I agree, they lock up HARD sometimes. One downside, chain and swivels need upgraded.

I run 650's. Over half of my coyote line are 650's now. I giggle a bit about the guys that go straight to buy MJ's on a thread about a different trap. Mj's are a great trap. They are also in a completely different tax bracket than Duke 650's. Maybe two tax brackets off lol. Anyways back to the guys looking at Duke 650's. The only upgrade you might consider as mentioned before is the chain. I change the chain setup on every trap to suit my setup so that doesn't really matter to me.

Yes

Awesome.Thank you Wheelers

Dave makes setters for ALL coil spring traps and jumps. I have several pairs and they are an awesome tool!! They also have a safety hook on them so you can lock the trap open if you are doing some work on them. Works great if you are adjusting pan tension and have a pile of traps to do , ya dont wear your hands out resetting all the traps.

My Duke 650's held everything that stepped on the pan. All good catches above the pad. And like said above, they bed real nice. I did replace all the chain on mine and used sterling type swivels.

Thanks Jacob....choices choices choices.

Anybody have any advice on pan tension adjustments??

I have 15. Let a landowner borrow two for a couple beavers and he is buying them from me. Get some One Hand Setters or eat your wheaties cause they’re a grown man trap! I consider myself a sufficiently strong guy and I bought some setters.

I've Run 2 Dozen Duke 650's this year mixed in my line. Caught a good pile of coyotes and a Handful of Bobcats with them.
Been very pleased. Strong Springs Lock up tight. The J hooks could used replaced like others said.
At 189 Dollars a Dozen Plus shipping They make a Darn Fine Trap. Yeah they arent U.S.A made , but Duke company is U.S.A based.
For the Price I'd say they are Hard to beat, unless your dead set on U.S.A products.
My Mj600's are nice , but not comparable at this price point.

Jerry is spot on.
Adding on to the pan will increase sub-par paw catching = toe catches.
Steer clear.

I always thought that when giant pans came in

Thanks for all the Information.Right now I'm leaning towards mb 650's.

I will stay with the MB550, single springs and offset jaws. Easier to set and I like the click of the pan when pulling it down. SET!

After watching Mark June's video I'm planning buying both mb 650's and mb 550's for different type sets I have in mind.

Also thinking of duke 550's in areas where a trap would be more likely stolen.

Just orders a 2nd set of the one handed setters for my cat bag if I remake a yote set I leave them in my set bucket and forget them when walking the cat line.
