TwisterNock ® US patent Pending
Better archery, better hunting
TwisterNock® is the first truly mechanical nock(Spring loaded). It delivers accuracy with great precision.
What are the benefits?
It adds speed to the arrow.
It adds accuracy to the arrow.
It delivers maximum kinetic energy to your target.
It rotates the arrow into the target.
It is very quiet.
It has a lighted version.
It has a buzzer version.
It rotates the arrow on the bow string right off the bat. The instant rotation of the arrow helps the spine of the arrow when the string pressure is at its most. It stiffens the arrow resulting in less flexing on the arrow shaft. This stabilizes the arrow much faster and creates better accuracy.
The conventional arrow start stabilizing after it leaves the bow string. That is why any attempt to spin the arrow, results in more noise and lost of speed and kinetic energy. TwisterNock spins the arrow mechanically. It is not relying on air drag to stabilize or spin the arrow. The angle of vanes are relevant to the speed and rotation of the arrow and they have minimum drag. Therefor it is very quiet and fast especially down range.
TwisterNock versus regular Nock is like bullet versus slug. The bullet keeps the speed and accuracy up down range. It does that mainly due to its rotation.
We put a whiteout spot on an arrow and shot it into a 30 yard target. The streak marking on the arrow confirms a full revolution in every 10"-11" of travel into the target ( With field point). Below is a picture of the whiteout test.
TwisterNock turns the Broad Head into the target causing massive tissue damage. Below are the pictures taken from the 30 and 40 yard shots. From the entry blade marks and the exit, it is clear that the broad heads turned into the hard target. These pictures were taken when we did the slow motion video. I would like to point out that the day we did the slow motion video, it was a very windy day. you can see on the slow motion video my sleeve is flapping in the wind. Even in high wind the arrows had no difficulty hitting the target.
How to use TwisterNock,
Place the nock on your bow string. Nock your arrow by pressing against the string and turn clockwise. This will automatically lock the TwisterNock in the charged position. It only discharges when you shoot the arrow or if you compress and turn the arrow to the left . You could also cock the TwisterNock in advance and just nock it on your bow string.
What size arrow does it fit?
The current TwisterNock fit any arrow with inside diameter of 0.244 to 0.246
They will be available for different size arrows soon.
What broad head to use?
Both Mechanical broad heads and Fixe blades performe well, in flight and into the target. We would like to point out that, due to the added speed and rotation some mechanical broad heads may open premature, causing the arrow to steer off. you may have to add rubber ring to keep them closed in flight. We have tried Innerloc broad heads both mechanical and fixed and have had good results with the. Also all mechanical broad heads that open from the back will work fine.
We have tested different fixed borad heads with TwisterNock. So far we have noticed, it works with most broad heads. As long as they are well balanced. The TwisterNock itself is a well balanced nock with precision performance. Trying it with old outdated broad heads is like trying to watch Hi definition on a regular tube TV. If the broad head is not balanced it will affect the arrow flight while it is rotating.
What Fletching to use?
You get the best performance with TwisterVanes. Fletching works best when it is at the far end of the arrow. The slightest drag will steer the arrow in the right direction, The rotation helps to stabilizes the arrow, therefore the need for fletching is minimal. You could use regular fletched arrow with plain TwisterNock(with smooth sleeve). Use right helical fletching. The TwisterNock will spin the arrow even with straight vanes, but it will be noisy. Overall, you will notice much better accuracy and flight pattern with TwisterNock.
TwisterNock works the same for right and left handed bow.
What rest to use?
Drop away rests will give the best result. You can use TwisterVanes without any speed lost. You cannot use any kind of fixed rest as the TwisterNock rotates as it goes through the rest and will kick off the arrow.
You can use TwisterNock with Whisker Biscuit.( you have to glue the sleeve on the shaft) There will be some speed lost but the accuracy and better penetration is noticeable.
Note: some drop away rests may need to be adjusted to make sure they will clear and won't bounce. With regular fletched arrow you may not notice if it hits the fletching, but since TwisterNock rotates the arrow, any interference will affect the flight of the arrow.
Is TwisterNock noisy?
TwisterNock rotates the arrow mechanically, it is not relaying on air drag to spin or correct the arrow. The angle of the vanes is relevant to the rotation of the arrow and its speed. TwisterNock is very quiet.We even tested it for noise by putting a microphone on the target and you do not hear the arrow coming especially the hard plastic ones. Also the spring takes away some of the initial impact of the bow string, acting as a shock absorber and resulting in a very quiet and smooth arrow departure.
TwisterNock has a lighted version to improve arrow visibility and arrow reterival. It lights up on every shot. It is steady light and stays on until you turn it off.
The battery in lighted TwisterNock is larger than other lighted nocks and last longer. The battery is replaceable.
TwisterNock has a sounded version ( with delay) to improve arrow tracking and arrow reterival when arrow is out of sight. It starts buzzing after a minute+ delay giving you enough time to get to your arrow and turn it off. We are still working on They should be out soon.
Note: Due to the fact that you get a very accurate shot with TwisterNock, we suggest tuning your bow with TwisterNock. When paper tune your bow with TwisterNock, You should get a bullet hole with the paper in front of the bow and at 4+ yard.
The object of TwisterNock is to stabilize the arrow and get a much better accuracy without wasting or losing any energy. stabilizing an arrow specially when shooting broad heads have been an issue. TwisterNock does it with the list drag necessary from fetching. Just think of it, less fletching, less chance of hitting a leaf or twig. With more accuracy and speed downrange. And to top it up, the damage it does to its target. It is like putting a blender trough it.
The recomended use of point is based on grouping in 3" circle at 30 yard and 4" circle at 40 yard shots.
The result could be improved based on fine tuning of your bow.
