I still don't think it's 22gr "DIFFERENCE". I think it said that was the total weight. Like I said, earlier, wouldn't you THEN have to subtract the weight of your CURRENT, STANDARD nock??

Areal Lumenock adds 22 grains.So arrow with a easton nock at 350 grains would now weigh 372 grains with Lumenock.

Jeff,
Fire away! The weight isn't enough to make a difference.

I make my own lighted nocks. One thing I do different though is I don't set them up to turn on when the arrow is released. I sand the nock just enough that I can pull it out by hand but it's still snug when it's in the arrow. Then I just turn it on when I get in the stand. The lights last a long time. I can get thru a season doing this. I have had to many not come on before when they were shot. So I fixed that problem.

Interesting,

I just ran a few number through Jackson website to look at FOC differences based on a 420 grain arrow (total), 29 inches length75 grain tip. 15 grain for fletches, 10 grains arrow wraps (enteredas nock adapter), insert weight 15 grains.

With a regular 8 grain nock, FOC is 6.3% (420 arrow weight)
With the lumenock, FOC is 3.6% (442 arrow weight)

Just general info. Even with heavier tips, the FOC will change a few %. Could be enough to through off a fixed bladed broadhead tuned bow and possible POI.

So now...when you subtract the weight of your standard arrow nock you get what difference??????

I can tell you from my limited experience......of maybe shooting 40 shots with mine ......beside hundreds of shots with my other hunting arrows NOT equipped with the lumenoks.....(out of my Mathews Switchback @ 64# and my Bowtech Allegiance @ 71#).....it makes NO DIFFERENCE.

I also have NEVER had one fail to illuminate.

That's my experience with the product.

Jeff,
I have had a couple not light up when they were shot. But for the most part they work great. I just fixed the problem by making my own and having the light on all the time.I have also shot deer with them that the nock was lit when it went into the deer but not after it went thru the deer. I guess something in the pass thru pulled the nock out enough to turn the light off. You can get the thill lite in green also. Use that with a green nock and it's like a flsh light..LOL Much briter then the red nocks. But I wouldn't use the green in the ones I leave on all the time. They are to brite when it starts to get dark.

If you drill holes in your nocks, won't that destroy their structural integrity? They weren't designed with this modificaiton in mind.

KW,
You are shaving very little out of the nock. I have shot them a bunch of times and haven't had any problems.

MC

How do you account for the extra weight you drill out?

Really, guys.....we're splitting hairs. Today's bows don't know the difference. I went from 100g broadheads to 125g with no sight adjustment......no tuning issues....nothing.

Just my thoughts....

Supposedly the clear nocks are made from a more fragile material,so you should use the Easton nocksI just made one with the rubber tubing and will be trying that one out to see if it's more reliable than the original,even though i have never had any issues with them.[&:]
