I’m a fairly longtime Hoyt guy after being a long time PSE guy.
I’d buy a new Hoyt every year.
From Alpha Max to Carbon Matrix to carbon Element to Carbon Spyder Turbo with the Z5 cam.
The following year when I went to pick a new Hoyt out I passed, was not impressed with the cam. Same thing the next 2 years. I settled on the fact the Z5 cam was Hoyt’s best work inspite of being told otherwise by others. I’m still sold the Z5 cam is Hoyt’s best cam.
Now let’s talk vibration. Hoyt uses the “Hybrid” cam system, string stop with an upper yoke.
Here is what causes some vibe and noise, the cam orientation. If your cams aren’t in tight unison they will vibe because they hit home separately from one another.
Time your cams @ full draw to hit together, some say top cam a smidge before, I prefer perfectly together. Then using a draw board, come off your stop, if one cam is delayed, you’re not good. Both need to hit, and come off full draw together.
When the bow then is shot, you have 1 finite termination to the cam @ rest and the bows engineering to squelch vibe and noise does its job.
Therefore, I’d say anyone having noise vibration issues, please draw board your bow. Check your cams @ stop and coming off stop. Check cam lean @ full draw !!! Cam lean can cause issues as well.
These carbon bows do not vibe or make noise.
Right now I’m currently restringing my carbon spyder turbo z5 because I noticed for some reason, the bow was “kicking” after the shot to the left side. Looking @ my cam marks I place where cams intersect limbs, I saw maybe 1/8th inch gap. Not bad for 4 years. Didn’t think it was the issue. So I decided to try other stabilisers or side bars thinking my face or grip had somehow changed.
Before I did, I ordered new custom strings from my Hoyt string builder , Viscosity Strings and sent the bow home to Connecticut where I met it while visiting family.
My brother who was a Hoyt guy and myself put the new threads on, set the yoke, and had bulletholes in now time.
I then just shot the bow into a bag target @ like 5 feet trying to set the strings in. I quickly noticed something, no kick. With an ultra lite grip, I shot, and she fell dead straight forward. I was in shock.
Moral of this long story ? Cam orientation is more critical then you realise. 1/8th inch !!! That’s all, nite and day shooting !!
Then I heard the combination of the shorter 6 inch brace, the speed and power it generates, makes cam orientation more critical. Not so sure on that, but I can tell you, 1/8th inch mattered huge on mine.
