I can't imagine an experienced RC pilot recommending an electronic compass to manage orientation. The OP is probably a millennial, judging from the question and the way he phrased it. Millenials don't generally ask questions of people; they just want to Google everything. And they go straight to electronics to solve every problem if they can. For example, I was an educational aide for 2 years in a middle school. Sometimes the science teachers would give the kids an option of using the textbook or their phones to look up information (a mistake to offer that option, IMO). I would go around and turn the textbook to the right page for them, because many aren't even capable of using an index. Most would push the book aside and spend 2-3 minutes Googling because they were convinced that the electronic solution is always better and faster. It's just the way they think, and a lot of their success in life will depend on learning to think a little more critically about their assumptions.
