I guess I feel a little like Jock Whisky, in the respect if I hunted 24/7, I may not need a cam.
Fortunately for me, I do have a job. Like it or not, I have to get up every morning 5-6 days a week, and go there. A cam, lets me know if I picked a good locatation, or a dead spot. Time is valuable, I have sat days in a treestand, to see nothing. A cam keeps me from wasting that time. As for lighted nocks, an arrow tells you lots. I have a lighted nock in my quiver for evening hunts. Not all shots are perfect, and finding an arrow, or an animal that would have been otherwise lost, is a plus. A range finder, is good to shoot a stump, and know it is 27 yds. My limit is 25 yds, I don't shoot well beyond that. So I guess each individual has their own thoughts. Like another said, do what is fun for you. On P&Y, and B&C, if you only hunt trophy class animals then it matters. If you hunt, because you enjoy the sport, it does not matter as much. Everyone would like to kill P&Y deer, but I get enjoyment from driving an arrow through a doe. So again, do what makes the sport enjoyable to you.
