Question: What is string stretch?
Answer: Elongation or string stretch is the amount that a particular string material will lengthen when put under tension. There is always some initial settling of the string and cable after the bow is built. Most of that stretch will happened before you ever get a bow out of the box. The last bit of stretch happens in the first 50-100 shots. That's why you should wait until the bow has been shot some before making any final adjustments or settings.

Today's string and cable materials and more importantly the string making processes, are far better than in the past. Because of that, string stretch is not that much of an issue for most bowhunters.

Be aware that physically damaging any of the individual strands of the string or exposing the bow to excessive heat can cause a string to stretch even after it has "settled".

Question: What is tiller?
Answer: Tiller is a measurement taken to help determine if the limbs of a bow are in balance.

It is a little confusing to describe since each riser is different between models and often within the same model depending on the year of manufacture. Tiller is the distance between the string and the limb pocket.

Here's what Parker recommends....

Crank your limb bolts all the way in. Do NOT over tighten, just snug the limb bolts down.

Back each limb bolt out an exact and equal number of turns until you reach your desired peak weight. Your tiller adjustment is set.

Question: What is an ARC Cam?
Answer: The ARC cam is a true innovation and a vast leap forward in adjustability and convenience.

Parker's new ARC cam is designed with built-in articulating draw length adjustment. This new design delivers the all out performance of individual draw modules with the simplicity of a built-in articulating module. The ARC cam guarantees you'll get the maximum performance out of every inch of draw length!

Question: What does the XP mean in your new 2007 products?
Answer: XP stands for Xtreme Parallel.

Engineering a bow with parallel limbs is more than just laying the limbs back at a different angle. To do the job right there needs to be a delicate balance between limb pocket angle, limb design and cam engineering.

Every Xtreme Parallel bow in Parker's product line has been extensively tested to optimize all three. An XP bow in your hands is nothing short of the ultimate in performance and vibration dampening!
