FAQ - Frequently Asked Questions

What type of Biscuit do I need for my setup?

In general, a loose fit is good, and a tight fit is bad. A tight fit can result in more noise and possible left-right errors from hand torque. All Biscuit sizes are interchangeable. This means that to switch arrow sizes, it may only be necessary to switch biscuits. It will not be necessary to buy a whole new rest. The following table relates the available Biscuit sizes to the available arrow types and sizes:

  • Biscuit Size
    Arrow Sizes
  • Small
    (0.300" inner)
    Trophy Ridge, Acc, Outsert Carbon, Axis 17xx or smaller Aluminum
  • Medium
    (0.320" inner)
    Internal Component Carbon, 19xx or smaller Aluminum
  • Large
    (0.385" inner)
    23xx or smaller Aluminum
  • Fishing
    (0.360" inner)
    Unfletched Fishing Arrows Only

Will the Whisker Biscuit Arrow Rest® work with fingers?

Yes. The Whisker Biscuit Arrow Rest® works well with fingers. When paper tuning a bow for finger shooting, the shooter must keep in mind that the normal tear shows nock-left for right hand shooters and nock-right for left hand shooters. It is possible to tune a bow with this rest on it to shoot a bullet hole using fingers, but you may notice that the arrow angles to the right of the centerline of the bow, and thus it will shoot to the right (for a right hand shooter).

If it isn't already, you may want to set up your arrows with the cock feather out. This will provide a larger profile of feathers in the vertical plane, which helps stabilize the arrow faster for finger shooters. Just remember to keep the arrow close to the vertical centerline of the bow (just to the left of the string), set the string nock about 1/4 inch high, and you will get good results.

How do you load a broadhead into the Whisker Biscuit Arrow Rest®?

The blades of a broadhead extend radially out from its centerline. The whiskers on the biscuit extend radially toward its center. This means that you can push a broadhead through the Whisker Biscuit Arrow Rest® without any problems. If you are using expanding broadheads, you may want to take extra care as you push them through to ensure that they don't open, or that the o-ring doesn't get bumped. Backloading the arrow nock first is also an option when shooting plastic vanes. The Quick Shot Kit and QS model arrow rests provide an entry slot for easy loading of arrows regardless of fletching or broadhead type.

How long does the biscuit last?

The biscuit should last at least several hunting seasons. If crushed excessively and repeatedly by an arrow, the bristles may take on a permanent set. High temperatures such as from a freshly hot-glued target point can melt the bristles. Too tight a fit around the shaft may cause excessive bristle wear. If any of these conditions occur, then it's time to replace the biscuit.

Is there a speed loss?

As compared to a prong style rest, the speed loss from 3" vanes is negligible. Four inch vanes or feathers with a 1 to 2 degree helical will produce a loss of only 1 to 2 feet per second. Five inch fletching will lose 5 to 7 feet per second, while using 5" fletch with a 6 degree helical will lose 12 to 15 feet per second.

How do you adjust the biscuit to fit the shaft?

The biscuit can be removed from the rest by loosening the two set screws. To increase the hole size, grasp the two ends of the ring on either side of the split and pull them apart while twisting the ends up and down. Only minor adjustments to the hole size are possible. Excessive adjustments may create a weakening in the bristles beneath the arrow where support is needed. If a gap in the bristles is created during adjustment, then the next larger size biscuit is recommended. A large amount of clearance around the arrow shaft does not cause any problems. A loose fit works best.

Does the Whisker Biscuit Arrow Rest® make noise when you shoot through it?

No. The overall sound of the bow is much greater than any sound made by the arrow passing through the rest. A whisper like sound may be heard during the draw back, mostly when using the wrapped carbon arrows due to the rough surface of the arrow. When using a smooth shaft, the draw sound is negligible. This arrow rest will NOT make a metallic squeak or click because no metal parts are in contact with the arrow.

Does the Whisker Biscuit Arrow Rest® work with plastic vanes, or only with feathers?

The Whisker Biscuit Arrow Rest ® works equally well with vanes or feathers. Speed loss will be the same, but the dynamics are different. Feathers lie down presenting a lower but wider profile to the bristles. Vanes stand up straight but pass through close to the base of the bristles where they are more densely packed together. The result is that both vanes and feathers fly at the same speed and accuracy at hunting distances.

Is there any wear on the vanes or feathers?

Yes. Vanes will show wear after substantial use, some brands more than others. Urethane based vanes seem to be the most durable. After 30 to 50 shots a scalloped wear pattern will appear on the outer 1/8 inch of the die cut edge of feather fletching. This does not affect arrow flight. Nor does it progress beyond the initial wear-in period.

What happens when the whiskers get wet?

During a shot, the whiskers spray water much as the puff type string silencers do when they get wet. The whiskers don't lose strength, swell, or change in any way.

What happens when it freezes?

Nothing. The Whisker Biscuit Arrow Rest ® will work in freezing conditions. However, if it gets wet, the water will freeze making the biscuit as hard as ice. So if the biscuit becomes wet in freezing conditions, break up the ice as it forms much as you would do on your clothing in a freezing rain. Tests indicate even a frosty biscuit performs well if the ice is broken up as it forms.
