Hello friends, Deer season opens up on Saturday, my bow is pretty dialed in (i think) and am shooting well. I'll be hunting with my 10 year old son who is pretty dialed in too. This is our first season. A friend of mine just told me that he would never shoot without lighted nocks. I'm starting to second guess myself as I do not have them on my arrows. I'm nervous about messing with my arrows 3 days before the opener. Do lighted nocks change the arrow flight? Do they need to be installed in a certain way/ in a shop? Can I quickly adjust for any changes? Do I really need them? Help this rookie out. 3 days to go and I can't sleep!
