I can honestly say there has been no piece of equipment introduced in the last fifty years which has changed my hunting experience in the least. I don't use a rangefinder or GPS. I hope to never own a cell phone. I wear better boots than I used to and I having some cooking gear which is pretty good. I have a lightweight stove but usually carry the old heavy one because I like it. My binoculars are better but my eyes are worse so that's a wash!
I agree with Jim re the ATVs and consider them to be an instrument of the devil. GD
