Welcome to PPRuNe Joea,
Though gadgets look attractive, I have found during my VFR GA flying career that simpler is better. I gave up on gadgets, and just focused more of my attention on forming a mental image for situational awareness. If you can remain situationally aware in the big picture, things like diversions are not such a big deal. You can sort of guess the heading and distance based on your continuing awareness, and then your calculation at the time of diversion more becomes a confirmation of the awareness you were maintaining anyway.
I hope than helps. Others will be along with their varying opinions shortly, Pilot DAR
