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.
