Nockturnal GT Lighted Archery Nocks 3-Pack, 20+ Hour Battery Life, Patented Bowstring Activated Linear Switch, Super Bright LEDs, Fits Smaller Diameter Carbon .204 .244 .246 ID Shafts

I really like these. It really helps me know when my form is good and when I make mistakes. I'm 48 and my eyes are not as good as they used to be. I like knowing instantly how good or not good my shot was. These are very bright and work well on sunny days too. They are pretty easy to turn off. They turn on as soon as you nock your arrow. I would recommend these to beginners but I think they are great for everyone.

I just received these nocks in the mail on Thursday, 1/2/14. I inserted the nocks into my arrows in a matter of minutes. One of the benefits that these nocks offer compared to the Burt Coyote Lumenoks, is that they don't rely on contact points on the edge of the nock to be activated. I shoot Gold Tip XT Hunter 5575 arrows. I didn't need to use any bow string wax on the nock prior to inserting them. However, if you are having difficulty inserting the nock, you may want to consider using some to make it easier while inserting them. The other recommendation that I have is instead of using a pliers to remove your old nock or insert your new nock, use a Gorilla Grip arrow puller. You don't have to worry about scuffing up or possibly cracking the nocks during the install or removal. The Gorilla grip works great. When I installed the nock, I simply lined up the nock with the cock fletching and pushed the nock flush to the end of the arrow. There was no prepping the arrow by making it square which was a considerable time saver. I went to the archery range on Friday morning and was extremely impressed with how efficiently and consistently the nocks performed. I used these nocks for approximately one hour and did not have any of the three malfunction. One of the most noticeable benefits of these nocks is how easy it is to turn them off. Inside of the nock is a colored collar. Once the arrow is shot down range, the collar shifts towards the arrow which activates the light within the nock. When you retrieve your arrow, you simply take another field tip, in my case I used the tip of a pen, and you insert it into the opening at the base of the nock, and push the colored collar up towards the tip of the nock until the light goes off. You don't need a lot of force, just enough to get it back into position. It is extremely simplistic. The one thing I was concerned about when I started shooting the lighted-nock was the additional weight of 20 grains added to the arrow. What I discovered is that the flight of my arrow is the same as it was with a standard nock. I currently shoot a Mathews Drenalin with a 28-inch draw length set at 65 pounds. I have been able to shoot as far as 50 yards and no pin adjustments have been necessary. The one, slight negative about this nock is that it is not as bright as the Lumenoks that I shoot. However, the nock is clearly visible at 50 yards away. I am planning on video taping a practice session to see how well the nocks are traceable after being shot I do not know how well these nocks are visible in natural light, because I have only shot them indoors. I strongly recommend these nocks just based on the ease of use and overall performance. If you are unsure of what to buy, purchase a couple different brands and try them out so you are able to find what best suits you.

Good product would buy again .

I like the way these nocks function. I’ve had the green, and wanted to try the red.

Background - I shoot every day. I bought these a few weeks ago to dial them in with broadheads (I am using Muzzy Trocar with the helic) in for hunting season. I found my broadheads were shooting fairly similar to my fieldtips without the Nockturnals. When I added the Nockturnals, it took me a bit to tune the bow again so that the broadheads/Nockturnals flew true to just arrows with fieldtips/Nockturnals. They are now flying identical out to 70 yards. When I shoot just fieldtips/regular nocks, those arrows shoot straight, but are about 2.5 inches high compared to broadhead/nockturnals. I had to make zero windage corrections to get the arrows to match. In practice, I have now shot the 3 Nockturnals a total of about 75+ times. Pros - 1. Have worked every time. 2. Are nice and bright. (When I was dialing in, I missed the target low under the target on one of my first shots. I immediately found the arrow...which was cool. Cons - 1. They are a bit difficult to turn off. Once you get the hang of it, they are still a pain. 2. Tool to turn off for $10?!! I know, you can use a toothpick or arrow tip. But that little tool you can buy is pretty useful. But if you need a tool for them to function...don't you think it should be included? 3. Even with the tool, they are still a pain. You have to make sure they actually slide up. Which is not that big a deal if you are used to it. But when i was first turning them off, I kept wondering if they were actually all the way off. Like another reviewer, on one occasion it didn't slide the whole way up and lit up as I put the arrow on the string. That doesn't happen to me now, but I have used them a bunch now. ****Seems to me that they could add a little slot for the tool to slide into to easily slide it up.**** Bottom line - they work every time! I saw a couple other reviews where the nock broke. I would just have to guess that they were wrong for their arrows or something. I highly doubt these will break when I shoot them. I will update my review if any break. I am buying 6 more so that I will have a dozen...8 for practice, 4 for hunting. *Shoot straight* 9/19/2016 Update - I now have hundreds of shots with the first 3 that I bought. The batteries are dead, but I continue to practice with them. I'm still a fan with no issues at all. I'll add 3 new ones to my practice quiver this week.

I started using the Nocturnal nocks to make it easier to see where my arrows hit the targets. Some of the targets on the field course I shoot are in shady locations and up to 80 yards away, which makes it hard to see the arrows even with my Vortex 6x range finder. The Nocturnal lights turn on when you release the arrow, so you can easily watch the flight path and see about where the arrow hit the target. (I say about because the nock and the tip are not always perfectly in alignment so it can be a little deceptive). Loved being able to see the arrows in flight, so in addition to the two 80 yard targets on the course, I moved back to 95 and then 100 yards just to try the nocturnal nocks and my new sight. ( I was also testing out a new Trophy Ridge React One Pro Dovetail which I highly recommend) Pretty amazing being able to follow the flight all the way into the targets. The Nocturnal nock tool made it very easy to remove the old nocks and install the Nocturnal nocks, it's easy to turn them off too. I'd suggest aligning the turn off hole with the white fletching on all the arrows. I highly recommend these and will be buying more when I run down the batteries on these.

Loves these reliable and provide excellent light for arrow recovery, highly recommend.

Absolutely love these nocks and have run them for years. Its amazing how long they last and the ability to use them over and over again before dying. I keep two sets because of this. One for target shooting, ones that have died but weight the same, and a set on my hunting arrows. It finally came time for new nocks on my hunting arrows and they changed the size of them. I just called Customer Service at FeraDyne and they confirmed the change. This matters if your string nock point and D-Loop are tied for the old style like mine. With the new "fatter" style, it pinches the nock.

BUEN PRODUCTO

Perfect nocks, very bright, easy to install. Great product for the price !!!

INSTALLED THESE ON MY GOLD TIP XT VELOCITY 340'S , PERFECT FIT AND HEY WORK VERY WELL !

I have used these before and work well with my goldtip arrows . Although i have had the occasional issue of turning them off. Updated reveiw: I to have had one out a 3 pack not working of two 3 packs. It seems that the quality may have gone down over the years because when I first started using them when they first came out I never had an issue until recently over the last year-and-a-half or so.

i have used these for a while and like them. I shoot FOB's so Luminoks will not work for me.
