SoCal,
This thread is about a specific GPS unit, not about your opinions. I am well aware that it is unwise to rely on a GPS as a student and have already disclaimed this out of the equation to avoid mindless (and endless) opinionated babble (i.e. mental diarrhea) in the replies.
No, GPS did not exist when the majority of today's experiences pilots got their Private ticket. Yes, it does exist today. No, it can't be relied on 100%. Yes, it can be used wisely. A seat belt does not work 100% of the time either, but that doesn't stop you from wearing one just in case, does it?
