    Hunting Firenocks

    Posted by Ronald Stewart on Dec 18th 2021

    I haven't killed anything since putting in the Firenocks yet but checking the scope for zero was fairly straightforward, just had to make a couple of slight adjustments which with lighted nocks was easier than ever. With the first arrows nock lite the second arrow was easy to put tight against the first. A couple of things that could be better are the way the circuit board goes into the nock could be easier. The way the tiny tiny tiny o-rings that goes on the tip of the batteries could be easier to put on but don't know how that could be changed, most of the difficulties are on this installer in this case to do with having big fingers that doesn't work very well anymore. I would and will recommend Firenocks to everyone that is looking for a good lighted nock that are fairly easy to install and very easy to turn on and off without any tools at all.
