    New Vertical Force Technology Reduces Bow Jump and Hand Shock

    Compound bows have taken a turn to new technology that greatly reduces the amount of jump and hand shock the bow has when shot. This new technology is called vertical limb technology.

    In previous versions of the compound bow the limbs where set so that when the bow was fired the limbs would shoot forward, this worked well except for the jump of the bow, as well as the hand shock within the riser of the bow. In order to correct for this a lot of different equipment was made in order to try and dampen the shock.

    Bowtech was the first to come up with this new vertical force technology, in 2003 they released 3 compound bows featuring this new technology. The VFT Extreme, Patriot VFT, Patriot Dually VFT. This new technology was a huge hit, bow hunters and archers all over were amazed and fascinated at how much this new technology reduced bow jump and hand shock after the bow had been fired.

    This new technology was such a hit that all of the other bow company’s started following suit, and started implementing the “Vertical Force Technology”. This new technology was implemented by angling the riser limb pockets at more of a horizontal plane, this allowed the limbs to sit at more of a horizontal plane. VFT works on the basis that when the bow is drawn the limbs are compressed in a downward motion instead of the old backwards motion.

    When the bow is released instead of the limbs shooting forward, the upper limbs goes up and the lower limb goes down. Because these limbs are the same they both store the same energy, which makes them equal opposing forces which in terms of physics means that these two forces would cancel each other out. Because the forces are equal and cancel each other out your bow does not pull up or down, and no longer jumps forward. This is science is what keeps your bow still and reduces the amount of jump and hand shock you feel.

    If you are still shooting the old style of compound bow, and you have not at least tried the difference that this VFT technology brings to the table I would encourage you to go and give one a try, I can assure you that you will not believe the difference that it makes. This is definitely something to keep in mind when purchasing a new or used bow.

    3 Ways to Reduce Hand Vibration and Noise

    Every archer at one time or another has experienced some sort of hand vibration or noise coming from their bow after shooting it. Its an issue that isn’t all that serious but does get quite bothersome, especially for those of us who hunt. There are a few things that cause this vibration and noise that we will discuss.

    Loose Hardware: One of the biggest causes of noise and vibration is loose equipment, mainly the sight and rest. If these items are the least bit loose they will vibrate when the bow is shot and make noise. To find out if anything is loose, take your finger and tap the sight and rest with your finger.

    If there is a vibrating tinging noise then simply tighten down the bolts a bit, making sure not to over-tighten them as the riser is only aluminum and strips very easily. If everything is tightened and the noise persists you may also want to get little cushion buttons and place them on the items that are making the noise.

    Limb: vibration: When the bow is fired the limbs create energy as they return to their original position. This creates hand shock in the handle and creates a punching sound. There are ways of greatly reducing both of these by putting Limb Savers on the limbs. When the limbs return to their starting position the shock will be dissipated through the silencers instead of the bow. I would recommend the Ultra LimbSaver – Ultra Solid Limb for a solid limb and the Sims Vibration Laboratory LimbSaver Super Quad Vibration Dampeners for split limbs. The other way to help get rid of overall vibration caused by the limbs and other equipment is to get yourself a good stabilizer, I would highly recommend using the Sims Vibration Laboratory LimbSaver S-Coil Stabilizer

    Bow String Vibration: The string when released will actually go past its original starting place and vibrate until it is at rest. This does cause vibration and noise as well. The way we fix this is to get string silencers. These are made of a rubber material and the fit in between the string or around the string and as the string vibrates back and forth these silencers absorb the energy and silence the string.
