The patent on the Grizz Trap was for the complete trap, not part of it. The language of the first claim on the patent was written wrong due to a misunderstanding between my patent attorney and the USPTO patent examiner. The USPTO office recognizes myself as the inventor of the Grizz DP concept.

One thing I will add to this post. There are many great ideas that have been invented for the trapping industry. Unfortunately, there is always someone waiting for the next big thing to come out so it can be copied.

I know what Rob Caven is going thru and wish him luck.

Most bodygrips look very similar to the one Frank Conibear invented.

I am really not sure if I do.I got six quite some time ago.I will have to look through mine.Come to think of it,Mark June said he has had his for 11 years.

Not 100% sure,i think they came out in 2005,GREAT TRAP....

The nature of opinions:

Unfortunately many folks mistake their own opinions for either facts, restatements of the law, persuasive arguments, or “the way the world works”. In reality, they are none of the above.

There are way too many opinions being projected as some type of authority. Opinions stated louder and more frequently are no more statement of authority than from the first utterance.

An opinion slightly modified to better fit a situation is still an opinion and of no real value.

The original post asked the question “Would you use Duke 550 traps?”
Again I answer the question. Emphatically, No!

Well stated Willy.

Hi Mark,

Thank you my friend.

I really liked you mb550 family photo.

How is school going? I respect you for following your calling. That takes very strong faith, and the courage to act upon it. Probably no one there to discuss trapping with? I like your signature for graduation.

Since retirement, it is best that I not get involved in legal arguments. That door is closed.

Stay healthy!

Willy,

Appreciate the nice comments. My family photo with Donna and Grace is one of my favs.
Seminary is wondrous for the heart and incredibly tough for the work load. I took 15 credit hours and my courses at this evangelical, non-denominational Seminary with the motto of "Preach the Word, Love Well" are;

Trinitarianism
Intro to Old Testament studies
Educational Ministries and Leadership
Greek II
American History of Theology
... and then I have a 4 man Spiritual Formation group that I'm leading in a spiritual sense.

So there is a bunch of learning going on, but I can't really describe how blessed I feel to attend. I have a VERY supportive wife!
We're all online because of Covid-19, which isn't optimal, but it the best we can do of course at this point.

You know what they say, "You're never too old to learn!"
Blessings
Mark

Hi Mark,

I sent you a Private Message.

After the Wuhan debacle, nobody should buy anything from China

I never buy from China!!!!

I buy from other people that buy from China, so I should be ok

Pretty sure it was 08, Rob was still in high school. Tim let him design and fab on his own.. Got my first one in 2010 to test here, Needless to say I was impressed. Now I have 10 dozen, I'm even more impressed. 10 seasons only 2 losses out of a bunch of fox and yotes. No maintenance except for 550s ran over by heavy equipment. Even the springs are still strong. I've got 10 of the originals, my wife will bury me with those .. There are situations and conditions were a larger jaw spread is better especially for straight fur trappin yotes.

The 2 losses were before I 4 coiled them...…...

Thanks Gary.

Has anybody that you know of tested by using a Duke 550 and a MB 550 at least 20 feet apart and at least two locations on a farm and tested on 40 or 50 farms or locations. Then figured how many coyotes were caught and what the ratio is.Just because a trap looks similar or identical does not mean it is or has the same ability.After two years or less there should be no question.

Do the non targets count?

I would think so as long as coyotes would be targeted. It would also need to be enough trap nights at each location.Coyotes would be the hardest to catch so they would have to be the focus.

I don't think all that is necessary especially in this circumstance. Because the taps are let's be honest, a exact duplicate the only thing that could be flawed with this trap is inferior metal or springs everyone knows the design is exceptional.

Even if it were slightly different it's still just a foothold for the most part traps are simplistic in design and that is what makes coil spring traps so effective . Basically jaws,springs, levers,base, pan,dog and chain . That's also why so many people still use so many long springs even simpler

Ok I know where your going but If one or the other trap catches lets say a grinner should that trap be replaced and set In new location? I just think there are to many variables to pick one trap over the other.

That is why you target coyotes As your main focus. Just as you would target beaver or otter.
