When I was young and dumb I used it. Haven't used it in years and I kill my share of mature bucks. Being a good woodsman, knowing your property and understanding how deer use it, and using thermals to your advantage is IMO the most important thing. Gadgets don't kill deer, people do. I do believe it is just one of the ways hunting has become overly commercialized. If you have to carry a backpack to carry all your gear hunting with you, your relying on your gadgets too much. I understand if your carrying additional clothing and such.
