The three-piece, Alpha-Brite Lighted Nock System begins with a Nock-Receiver insert with a six-sided interior cavity designed to accept a combined LED unit and translucent pegged Alpha-Brite Nock. The Nock Receiver is glued into the nock-end of the arrow and indexed with the vanes.
*Package includes 3 translucent Alpha-Nocks, LED Units, Nock Receivers (for arrows with shaft sizes .297, .300, .305 I.D), a Nock Receiver and Alignment tool, and a refletching tool.
I'm a long time vertical bow shooter and bought my first crossbow from Tenpoint this year. The bow I bought requires Alphanocks or the warranty is void (questionable business practice since it creates a "closed system" effectively eliminating the use of any 3rd party bolts, nocks, etc).
I wanted a lighted nock for all the reasons any would want one: a) easier to see where you hit your target, b) easier to find your target than no illuminated; c) assists in recovering the animal should the animal carry it some distance.
Here is what you as the buyer should be aware of:
#1. the nocks are overly sensitive and will engage the light mechanism as you move through the woods, crank your bow or hoist your bow up your tree. There's nothing like getting 3 steps up my tree to look down in the pre-dawn to see half my quiver lit.
#2. it's difficult to turn off the lighted nock in the dark. To turn of the nock, you need to remove the nock from the receiver, remove the light stick, pull the light stick out. That's easy. What's difficult is re-inserting the light stick in the dark or while walking back to your vehicle and making sure that the nock aligns properly. These only nock one way.
#3. the power of the light is contingent upon how far forward the light stick bulb is pressed to engage the battery. In roughly half my shots, especially during day light, you can't see the lighted nock in a target. It's simply not bright enough due to the fact that the light stick is not engaged.
#4. a by-product of #3 is that sometimes you don't know your nocks are even lit during the day. They could be bumped or jostled while on stand during daylight. And b/c they have engaged enough to draw battery but no bright enough to see that they are light, they will burn down your battery.
In general, these are clever design that doesn't work that great and creates to many inadvertent engagements of the light stick. Compounding this is Tenpoint warranty which demands that you only use their nocks in certain bows -- or -- your warranty is void. When a manufacture or publisher of any kind makes a lousy product and takes away my choices -- which is exactly what Tenpoint has done -- this leads to a poor customer experience.
I don't write negative reviews to vent. I write a negative review because I want Tenpoint to FIX the product. To pay 4x as much for bolts as I would a vertical bow and then to have a lousy experience with the product, I would hope that someone at Tenpoint would create a suitable remedy.
Lastly, I feel so strongly about this that if I can't get an appropriate solution for the 2021 season, I will sell the bow for whatever I can get. Please note that spent almost $2k on this.
First trip out with these and notice light is on. Turn it off. Look down later, on again. Second trip out and nock is missing. I’m not happy.. Come on Tenpoint. For what you charge for these, make a better product.
I shoot the pro elites from my turbo gt, and decided on trying the alpha nocks since they are supposed to be slightly more accurate. They are definitely accurate! The problem I have is once shot the alpha brite has a slightly "transparent" green nock. It is very hard to find in any daylight. My cousin shoots the clear luminocks from his Matthews and I have no problem seeing those across a 125 yard food plot. I've already lost 1 bolt this season and didn't see the 2nd until I was 5 feet away. So I'm saying buyer beware on the alpha brite until tenpoint comes out with a clear nock!
