I've flown thousands of miles behind GPS, and love it.

Any products by Garmin or Lowrance are great, just great.

They really know what they're doing.

GPS turns navigation into a no-brainer, from the rather
complicated proposition which it used to be. It removes
all ambiguities.

On my plane, there is a mapping GPS on the pilot's
control yoke, and an totally independent one (smaller)
for the co-pilot.
