I get what you’re saying but I’m not sure I'd call lighted nocks and wraps non-usefull. An argument could be made for unnecessary I suppose. I shot feathers for a long time to minimize the weight on the nock end and attain better broadhead flight but found them to be pretty loud and after a certain distance they had more drop than a vane due to high amount of drag. I still shoot feathers on my trad setup though.
Yes we need to pick our battles. I see the lighted knocks as a cool factor thing, That is they look cool on video. Yea they may aid in recognizing a shot placement. Though in my honest opinion I feel the potential gain is largely lost if not on video. Me sharing what works for me is offending to some and for that i am not sorry. I am sorry some take offense, though this is just my take on the matter.
Perhaps I am overly simplistic, though I have done well in terms of deer recovery without lighted knocks. I have also done well in terms of arrow recovery without lighted knocks. If the quality / durability of the lighted knocks was equal or better in terms of durability & promoting good arrow flight I would perhaps have a different perspective. If the lighted knocks added no extra weight to the back of the arrow Id have a diffrent view.
For the responder that suggested a small narrow band of reflective wrap to aid in finding the arrow. This seems reasonable to me.
If folks are really inclined to use the lighted knocks & wraps, I do not mean to criticize. I just feel they are falling into a marketing ploy. If you are one to video your hunts I can see where this would enhance the video. Though as a individual that does not video my hunts Ill prefer to add weight in the opposite end of the arrow enhancing FOC as opposed to detracting from a higher FOC.
My focus is on true arrow flight to & through the target animal & quick clean kills. In my experience this is best accomplished with focus on other benefits like structural integrity & sharp really sharp broad heads that slice there way through highly vascular tissue. When this is exercised properly the wow factor of experiencing deer expire inside of 50 yards far exceeds the cool factor of a lighted knock.
You can have it both ways though I feel my chances are better of a clean shot through & through with less weight on the rear of the arrow while using a high quality knock. There are some fairly good quality lighted knocks & if you do insist on using a lighted knock, Id encourage a strong emphasis on striving for quality.
For me I'll put more focus on the BH side of things. Too few recognize the value of sharp broad heads that remain sharp when passing through the rib cage IMHO. This is the cool factor that too few appreciate as relatively few are promoting this aspect, would be my point of view. Really short recovery is how this cool factor is realized. This approach is what has been working well for me.
YMMV
Can't argue that the lighted knocks do look cool on video when every thing works right though.
