Guys I have another question for you from my damaged brain, sorry if it comes out wrong, some of you know my father was a DEC Archery instructor before he died in 1995.. He had a couple rules he put on top of the state, one was ethical shots, he spent hours making sure hunters only took ethical shots, another rule he had was blood trails, every hunter I’ve talked to they say the same thing how much he instilled in the hunters on how to track deer. So why is it in today’s technology you cannot come up with a GPS in the arrow or the lighted nock…. Woody
