I have recently done my PPL as well, And the wizz wheel scared me, but I knew I had to learn it to do my nav exam. I also bought an electronic calculator. Guess what I use now? I use the wizz wheel, It is so much quicker.
Now most of you will say I am computer illiterate, But computers are my bread and butter. I love gadgets, but in my opinion u can't reinvent the wizz wheel.
I'm not saying I use it to plan all my flights, I tend to use Navbox proplan, But I have in the past had a last minute mid air change of route, due to weather and then I have used the wizz to get drift, the rest of the calculations I do mentally. The more I fly the more I am getting used to compensate for the wind, while Im on the move.
