I use Nock Out lighted nocks, I use the X nock so the weight is right at 21gr. Thats about 14gr more than my standard X nock. They are very reusable and I see minimal arrow flight difference out to 50yds if any at all
Love them!!

 

I started using Lumenok's on my Beman Precision Hunter 340's this past year and would never think about not using them. They fly great I don't notic any change in flight. And yeah there reusable just have to flex the tip of the nock to reset the contact points

 

Welcome to AT. Yu are discovering the down side to archery. The bow shops are going out of business, lots of them hire minimum wage workers and you get what you get! Take the bull by the horns and buy a bow press, build a draw board, and work on your own equipment. The info is on here and YouTube. If you want to see if lighted nocks effect arrow flight, buy some and test it, or add weight to your nock (glue a couple of BB's or something and shoot it)! To me, thats the fun of archery, change something and go shoot it!

 

Yes they will change your point of impact as the shots getting longer.

 

Many times it's more about nock fit than anything else......but anything that changes the FOC and overall arrow weight will also have an impact on POI. It might take 20+ yards to see it but it will change.....it has to. If you hunt with them you need to sight in with them.....problem solved.

 

For me the nock fit is the biggest thing I find with poi difference.

 

deadquiet: That's what I guess I was trying to say (I want to practice how I'll hunt). That said, could I just buy some lighted nocks and use them on all my arrows as I practice and hunt, or will they only light up a couple of times?
Same Q for broadheads too... Shouldn't I be practicing with broadheads I'll be hunting with, even if the weight is the same?

Thanks all, just new to this and want to do it right (as inexpensively as possible!)

 

Anytime you change a nock type lighted or not it can change arrow flight. All nocks fit on the center serving differently

 

80 yard group with a nokturnal lighted nock and 2 regular nocks:

I never had an issue.

 

The nock out lighted nock has a practice mode where you can shoot it and it wont light up. I have used them for several years with no problems. Comes with inserts to fit different diameter arrows.

I use Nocturnals and have noticed zero difference in point-of-impact out to sixty yards. I'm sure Levi could detect a difference, but I can't!
