I hunt because I enjoy it. If there is a product out there that allows me to enjoy hunting more or allows me to be a more effective hunter then so be it. If I can afford it I have no problem trying the latest and greatest.
To give you an example, I like Cabela's Dry-Plus outterwear. It keeps me dry and warm and allows me to stay in the field longer. Also a lazer range finder allows me to be a more effective hunter. I am frugal with my money but why not take advantage of the latest technologies.
