I too like many high tech things, but mostly clothing related. Waterproof/breathable rain gear, boots, etc. I carry a cell phone which works well where we hunt and a GPS, and a solar charger and flashlight. I just always prepare for the FUBAR scenario? Doesn't happen often, but........?I'm old school, I take note of landmarks and drainage's in the area and while I have a GPS I mostly use it if I am in a area that has a lot of private. But I usually try and avoid those those type of areas.
I am also fairly good at telling distances within a few yards so I don't use a range finer either. But I am addicted to my binoculars.
When I first started bow hunting my camo consisted of Levi's and a flannel shirt. Rain gear was a old piece of waterproof tent that we cut up to make a poncho out of. But I also like my insulated boots where I don't have to wear 3 pairs of socks and have to stomp around to get the feeling back into my toes on cold mornings.
I remember when the civilian type of GPS's first came out and a couple of friends purchased them. While hunting down in Arizona in a fairly flat area two of them walked right past the truck and ended up at a paved road two miles away and they were using the GPS to find the truck.
