Frequently Asked Questions
What material do you recommend for my bow?
We offer 2 superior quality materials for you to choose from.
452x is 100% stable and strong. This material will NOT stretch under normal load making it an awesome value for modern bows where cam timing is critical. 452x has the most color options. It has very good peep control and holds Halo serving incredibly well. It is a blended material to add the zero stretch characteristics.
Astro will have the most stable peep. This material will have very little stretch throughout the life of the string making it a great material for modern bows with critical cam timing. The string bundles stay very round and consistent. No fraying is also a added benefit of this material. Astro is a 100% HMPE material.
How many twists can be put into a bow string?
ProString adjusts each string for the optimal number of twists at the factory. This ensures you will have an absolute minimum of peep rotation when you install your new string. If you need to, for setup reasons, you can add several twists to your cable or cables to get your bow into time or program. On your string it is better to remove twist than to add for peep stability.
What do I need to do to my string at install time? How many twists do I need to add?
We pre-twist each set at the factory, so you do not need to change this. If you need to fine tune your timing or program, we recommend adding or removing 1-2 twists to the cable. Once again, we pre-twist each set at the factory but if you need to fine tune your peep alignment, a ½ turn will usually be enough. Do not adjust more than 1 time per 100 shots to allow the string to settle in between adjustments. Serving life will be drastically reduced if excessive adjustments are made, voiding your warranty.
What is the life of a bow string? And how do I know when it is time to change them?
Strings are a normal wear item, think of it as normal and necessary maintenance, like changing tires on your car. You can run them until failure and then change them, or prevent trouble and do your maintenance before you miss the shot of a lifetime. String life varies with poundage and use a bow gets.
Very often target shooters get tens of thousands of shots from a string before it needs replacement. Most high end users replace all strings and cables every year to be certain they will not experience a failure at a critical moment. We recommend changing your set at least every 3 years. The longer you wait the bigger risk you run of failure.
Look closely at the string when you wax it, look for fuzziness, fraying, wear on your center and end servings. Look closely at the ends where they go over bumps and edges of the cam. Check for separation in the serving, when the serving actually gets gaps in it. Small areas of exposed strands on the outside of a tight radius can be quite normal however.
If your peep suddenly begins to turn to a different place, this may be a symptom of a broken strand. Replace any string with this symptom immediately as you will almost certainly do damage to your bow if it breaks completely!!!
