If a chart and compass are gadgets, then so are wings and tail. In my
book, the "gadgetness" of an aviation object has some relationship to its
necessity, complexity, and pronocity for failure. That which is
fundamentally necessary has lower gadgetocity. That which is fluff,
complex, and only peripherally related to the fundamental object in
question has higher gadgetocity.

As a gadgetologist, I love gadgets -- especially aviation gadgets -- and the
higher the gagetocity the better. No single gadget has given me more
pleasure than my Garmin 296, both in the plane and in the car.

To the OP: I think you need an aviation GPS.
