I have a 2002 ultratec with a whisker biscuit rest on it, and gold tip arrows. Everything is spined right, but I am getting bad groups. My arrow points are hitting low left of the fletching, and the arrows seem to fishtail and not fly true....whats wrong? What can I do? Which direction should I adjust my rest?

Get rid of the Whisker biscut.

Have you paper tuned the bow?

I don' t know about the Whisker Biscuit, but do Paper Tune your bow. Also make sure you follow through when you shoot. Don' t drop your bow arm until you hear the arrow hit the target.

question who put the rest on? restes are generally left abit of center. were is your nocking point, things to try first see were the are at. i know nothing about a wisker biscuit. cuold this be a speed thing? arrow are diffently going to drag on the rest, and that going to effect something and speed is going to compound it.....

I have the WB, with no arrow flight problems. Like anything you change, you' ll have to retune your bow!!!

Porpoising usually indicates a nocking point problem. (POI arrow is tilting up it is too high nocking point, arrow tilting down to low nocking point)

Fishtailing is usually caused by one of two things arrow stiffness (spine) or Arrow Rest Adjustment. If spine is ok, your rest may need to be moved to the right to ensure no contact with the disc or ring of the WB. If being diverted down, the rest may need to be raised or tilted depending on the model. Just a guess.

Is it installed correctly (WB)? Did you buy it at a local proshop or can you goto a local shop to help setup? Your owner manual should have a section on tuning your bow, look through that and determine what is happening for sure with arrow flight. You can also find lots of info on the web by typing in Tuning a Bow in any search engine. Most Bow manufacturers have a section on their sites as well.


Oh BTW, I did have 2 buddies who had to adjust their sight pins for POI after tuning and switching to the WB. But you must first fix the flight, before doing any sight adjustments.

Montana- Many of the above suggestions are good. Take a close look at your WB and your fletch alignment. On my Razortec, I have to shoot cock vane up to get proper clearance. Also, which WB do you shoot. Is the biscut set square and parrellel to the string?

For tuning help, the suggestion of seeking a pro shop is a great one, if you' re a do it yourselfer, go to the Easton arrow site and download their tuning manual, worked great for me.

As far as the WB overall goes, you need to evaluate your uses and needs. If you are just hunting and desire a rest that will eliminate some of the problems like arrow falling off the rest etc. then the WB will give you enough " perfect" arrow flight to fit your needs. If you' re going to shoot targets, 3D, or other competitions, it may not be the best rest for you.

Two things are for sure! 1. Everyone here will have their favorite and will tell you, and 2. my WB is as good as any rest I have used (for my needs).

No matter what rest you go with in the end, it would benefit you greatly to get a tuning manual. Good luck

The wisker biscuit will allow you to shoot perfect groups if tuned properly. You do not need to get rid of your ideal hunting rest to get good groups.

I' m curious as to how you know your arrows are properly spined? What did you do to prove that? Going by a chart does not work. There is an ideal poundage to set every bow at, to get the exact correct spine on a given arrow.

I wanted to add, you should check for fletching contact on your riser. Use some powder to see if there is it is interferring.
