ive tried everything with these deltas they keep diving way down, ive built out shelf ive lowered nock point tried raising it nothing is working i dont get whats going on they dive straight down after flying about 12 yards
i even shoot a delta head that the tip is very bent and it flies a ton better then a non bent one
The delta is the widest Zwickey, right?
Try orienting the broadhead horizontal. That is, horizontal if the bow is held vertical. My theory is that it starts to deflect the wind upon release due to the paradox of the arrow. Oriented any other way, the head becomes a paddle and will start to steer the arrow and rob it of some speed. But with a horizontal orientation, it slices through the air better. I sometimes shoot the No Mercy & that fixed my drops and funky flight patterns.
I also shoot the Grizzly Kodiak and found that when using a straight 4" fletch, the cock vane had to face inward otherwise the same problem resulted. But on my 5" helical, the cock vane orientation didn't matter at all.
In all cases, I mount my heads horizontal & get more consistent flight that way.
i tried mounting it different ways and still same has happened, however if i shoot one with the really bent tip it flies good even on a bad arrow missing half fletching
Given all that you have tried and all the input from everyone, I suspect your problem has nothing to do with the broadhead.
I agree with toej. I've shot Zwickey Deltas (2- and 4-blade) for more than 40 years, on carbon, wood and aluminum arrows, mounted vertically, horizontally and at an angle. Have never had a problem with them. One of the best flying broad heads out there, IMO.
all thse problems starting when i i went to an anchor point past the corner of my mouth which is earlobe pocket in jaw, i started getting string slap and all that stuff, i just put a 200 grain vpa on at my old corner of mouth anchor and it goes where i look, does this make sense? is it possible i was throwing everuything out of alignment before by drawing past my old anchor?
Torturing, or dropping bow arm?
dont believe so, i put a new zwickey on and the arrow fys good even with a fletching missing almost a whole flethcing this is weird
I think when you starting drawing farther you made spine weaker, try another spine.
i got some full length 340 spines coming, so if i went back to corner of mouth i would be good with 400s?
my draw corner of mouth is 27 3/4 and new draw is 28.5 thumb in jaw pocket under ear
I've had the same problem. I always tune by bareshafting but it didn't seem sufficient so u went to paper and discovered a nock high issue. Fixed it them my deltas shot real nice.
i have moved my nock up and down did not fix anything
If your anchoring in corner of mouth and get good flight and your draw arm is align with the shaft go with it. Over drawing can cause alignment issues.
You definitely may have changed the spine needed pulling to your new anchor point, but it's easy to malign your draw hand with the bow at that anchor point, that's where I pull too and always have. It's quite possible you are torquing the string. Pay attention to that for a couple of shots and see if that cleans anything up. If it don't it don't, but it's worth a try
Over drawing was a big problem of mine for awhile and it would give me all sorts of random flight results with broadheads...I'm guessing from torque. I thought that back tension equaled pulling real far but it isn't. Now I hit my anchor and use my back to put my arm in alignment and my flight issues are gone.
The overdraw issue my be it.
I was shooting a lot prior to my bear hunt this fall.
I took two bows that I thought I was shooting well with. When I pulled them out to practice at camp, it was, well- embarrassing. I was all over the place. I think that overdrawing was my issue. It took quite a bit of practising with one bow to get back my confidence.
Kind of funny, but the way I "fixed" it one year was I started practising with arrows that were marginal in length- the back of my STOS broadhead would touch my bow hand, the arrows flew so nicely that I intentionally shortened my draw length to use them. I had forgotten about that this year.
Your broadheads may not be on straight they need to be spin tested
Or as you drew longer you were putting odd pressure on the string. Pulling more with the middle finger causing the arrow to bow. I've seen alot of shooters pull the string with very uneven finger pressure and those arrows look like they are being test flexed.
Yes, NHbuck, drawing past your original tune DL can cause this. Toe jammer's post X2,3, whatever. Again.
I have shot Zwickey's for several years now and never had an issue with them diving on me. Now I have had a poor release every now and again. But I believe what the others are saying about a "longer draw" and the weakening of your spine. Tinkle with your brace height, keep it simple and try not to over think it. Take a minute and put the bow down if it's becoming frustrating. Sometimes it does me good to walk away for a day or two when things becomes frustrating.
If you make a change and it does not work switch back to what works

Been shooting Z Deltas since the mid 80s....
No Problemo....
I hope you get the issue figured out and resolved.

why you changing anchor? just go back to what worked before..... all this advice including mine and everything you ever heard or read take it all with a grain of salt,,,,,, stickbows you do what works for you..
already did that as suggested i was over drawing, shooting much better now thanks for the help
