Came to this video browsing Youtube and thought it would be interesting to send link here.

Wow :thumbsup:
-
well, that was interesting. I wonder how many dry fires a typical bow can take?
-
Well, zay are ze Germans no? LoL. Neato. Those bows seem like a great value for the money.
-
Wow, 72 dry fires
-
i cringed every time he released.
-
cool video, I have read before that hoyt dry fire tests their limbs also. I think 1000 times was how high they went
-
Interesting...I wonder how much that black bow holder (at the handle) in there helps?
It is large enough that the string must also hit it taking some of the force and energy from the bow limbs.
I ask because every time I see something like this, I always wonder where the energy is dissipated and how a device (like the bow) absorbs the near instantaneous forces that are not supposed to be there (or are not there when an arrow is launched).

Nice video! I wonder how many #s that bow is?? That bow shop is awesome! lots of nice tools ..This pic is of a 46# @ 28" D/R hybrid longbow I built 3 years ago has been dry fired over 40 times by its owner.. The string in the picture was one of my "shop" strings I use to tiller bows and try them out after finishing..It typically has a skinny endless loop D97 FF string built by LBR with no string silencers. Limbs are 040 glass, actionboo tapers and 024 zebrawood veneers, it has no stress marks or cracks. She still shoots it when she is not shooting her new Olympic style bow.

I, too, was wondering about the bow holder not allowing the string to complete it full forward cycle, thus adding an additonal layer of forward stress.
Still impressive and that shop make me drool.
thanx for sharing

A bowyer once told me that a good bow should be able to handle a dry fire without issues. He said a lot of bowyers say that the bow can't take it to give themselves a warranty out. He may be right, but that video still made me pucker
-
I'd be interested in knowing how that bow performs. Seems like a bowyer could make a bow that would withstand a lot of dry fires, if he was willing to sacrifice a lot of performance.
A couple of years ago I blew out the top tip on my Black Widow recurve in an accidental dry-fire, from full draw (31"), on a 62@31" set of limbs. Dragged the tip of the bow about 2 inches through the fiberglass into the limb. Bow never unstrung, and remained all in one piece. Wasn't a good day for me though.

I had an old Bear Kodiak that didn't survive one.
-
Two observations:
1. I only saw 7 dry fires, and the way it was edited, only 3 in a row at best. The guy might as well write 172 or 1700.
2. Why was he afraid to hold it?
-
I have dry fired my sarrels a couple times due to nock failure. No damage yet, but no way I would try something like that!

It does look like the black piece holding the bow is absorbing some energy, and the editing made it difficult to see if they actually dry fired it more than a few times, but.... It's a pretty sweet promotional video.
I got a kick out of it.
-
Being that Bodnik is not a sponsor is it fair to criticize them without allowing them to respond ?
-
This man on video is master bowyer of BearPaw. You think that is fake ?
That bow is just good, accept that
-
Looks like a nice, professionally produced video by a reputable manufacturer. Criticism seems unwarranted.
-
There are always the NAY sayers and pick something like that apart. I would say for the sake of time they edited it. Bearpaw makes some Quality stuff. Think about this have you ever dry fired your own bow? did the string hit you in the back of the hand? I haven't ever dry fired my any of my Bows(thank God) but I think that is a non issue (JMO) What I would like to see is that test done on a Heavier bow say 60lbs? Now that would tell you something. I have never held or shot a Bodnik Bow, but if there willing to video a dry fire test on one of there Bows, I might have to check them out. Looks tough enough to Me....

I've seen quite a few bows survive a dry fire or two, but then I've seen a few that didn't survive the first attempt....

I think the test is valid. Your hand holding the bow isn't rigid either. Granted the bow was 45# and the energy storage isn't very high for this type of mild rd longbow with 58" length. But 100 dry fires is still pretty amazing.

Checked out the info connected with the video. It looks like this video is a work in progress about a new model bow that is being torture tested before production.
With that in mind, the arty slow motion scene could be for capturing the final fatal dry fire. Curious to see how many dry fires this bow survives. The caption says they stopped at 72, but the guy running the test must be dying to see how far it goes.
I mean, nobody will sell this bow after 72 dry fires, right?
-
I remember a video from Bodnik, shooting with a 50 lbs bow at a concrete wall with carbon arrows at full draw and at short distance. According to this video, his carbon shafts stayed unharmed, shot after shot.
When I do so, my shaft is ruined after just one shot.....the part where the point is, looks like an opened umbrella after just one shot....
Since then I watch the videos of mr. Bodnik with mixed feelings... :)

These bows are brutally strong and ugly as sin.
They come with a 30 year warranty.
They're as fast an as efficient as any bow I have ever handled.
I don't own one, but have shot every model but the Hawk recurve.
I trust the test
I think Bearpaw losses some of my votes because they focus purely on function with their products and little towards the form.
For that reason I tend to lean my personal purchases towards custome and unique bowyers.
