The Spinning Insert Advantage

THE SPINNING INSERT ADVANTAGE
Arrow Flight/Penetration – Better arrow flight equals better penetration. There are many aspects to good arrow flight - to many aspects to go over here in detail. But, we will list a few such as arrow paradox, shaft spine, fletching (helical-offset), broadhead design, archers form, bow setup, etc.).
Arrow Flight/Penetration with Spinning Insert – The „spinning insert” allows the broadhead to take the
easiest path thru the animal due to the free rotation of the broadhead, independent from the arrow
shaft. The broadhead is free to deflect off bone instead of trying to cut through it. A “conventional/standard insert” follows the arrow shafts path, which is set, due to friction from hide, muscle, bone, and vital tissue on
the arrow shaft.
The “spinning insert” allows the arrow to continue its rotational force once the broadhead makes contact with
the animal. With a “conventional/standard insert” once contact is made with the animal the force of the arrow is used up. The “spinning insert” allows a longer force delivery since there is not a sudden stop to the arrows rotation.
Arrow Flight/Broadhead – When bow, arrow, and archer are tuned to perfection you may still have trouble with a broadheads arrows flight. Fixed blade broadheads have a steering effect on arrows like the rudder on a boat. This is why many fixed blade broadheads are vented as to lessen the rudder effect.
This is the reason for mechanical broadheads being invented in the first place. The price paid for blades being vented are weaker blades, more surface friction due to vents clogging with tissues, and noisy arrow flight. What about mechanicals? Sure the arrow flight is better, but at what cost? Smaller weak blades break and bend, there is massive loss of energy to open the blades on impact, sometimes blades don‟t open on impact, and at times there is complete broadhead failure.
Arrow Flight/Broadhead with Spinning Insert – With the “spinning insert” the
Broadhead does not spin at the same rate as the arrow shaft. This dramatically lessens the broad heads steering and wind plane. The “spinning insert” allows fixed bladed broad heads to fly like mechanicals or field points (with a properly tuned bow).
Other benefits:
Allows archers who cannot draw heavier bows to hunt bigger game due to added penetration.
Allows archer to lower draw weight and achieve the same penetration
The use of any “screw-in” broadhead made, allowing the archer to use their favorite broadhead.
Makes every broadhead a better penetrating broadhead.
Less arrow drift in wind conditions.
No more indexing broadheads.
Compatible with weight tubes in arrows.
Our objective is to make quicker cleaner kills with less stress and suffering to the animals we hunt. No broadhead will make up for a bad shot. However, we can limit as many variables that go into a bad shot as possible by lowering draw weights so we can hold steadier on target. Shoot soundly designed fixed bladed broadheads, and have your arrow tuned to perfection. The “spinning insert” will allow you to do all these things and give you more penetration too.
We‟ve had much technological advancement in bow design. Now it is the arrows turn to advance! That is what the “spinning insert” does – advances arrow technology.
Good hunting,
