well then again i have to look at it from another standpoint as in the ART of the trade...............most of us old timers (yeah i'm 52 now) were taught how to do things without fancy tools, and certainly didn't have radios with end point adjustments.............we did everything mechanically. doing things with a ruler is easy enough if you've done the setup this way over and over, but the meter does make things easier.............it just doesn't teach a newbie anything. with all the new ARF's and interest from new fliers has come the development of gadgets to get them in the air, but doesn't really convey any of the secrets.
i'm finding a lot of things have changed these days.........ask most newbie carpenters what 3-4-5 means.................they'll look at you with dazed and confused eyes.
gadgets are here to stay............may as well own em
