There are a lot of helpful techniques and pieces of equipment, but nothing works as well as having a plan, knowing where you started, and knowing where you are located at all times. Everything else keeps you on your planned route, gets you back to it or helps you lay it out. That is why the method I use constantly and regardless of any other gear or techniques I have, is keeping the map in my hand and using terrain association. It always works, needs no batteries, and the only problems I have ever had with it was when I made a mistake and doubted what I could see with my own eyes. Build the skill and trust it. All of the other things are helpful and useful, but you still need to know where you are on the map at all times.
