My idea of survival gear is what I can rely on when high-tech gadgets fail. High tech is what's gonna distract you from the business of survival when the grid goes down.
A basic 440stainless knife, a sealed matchcase with strike anywhere matches, a lighter, 20 feet of heavy twine, a space blanket, disposable poncho, antibiotic goo, a compass, handwarmers, as flashlight, a lightstick, 32oz of water. I carry that stuff every time I'm in the woods more than 100 yards from my car.
High tech is my cell phone (no service where I hunt and fish).

High tech things break- esp around me, the most high tech survival instrument I carry is the semi automatic action on my 10/22

GPS unit and cell phone about sums it up. Since they rely on batteries, I wouldn't consider them survival gear because when you need them most, they may not work. Survival gear is nearly always very simple, compact, and dependable.
