Im sure that owners of competition ready sailplanes can afford a better GPS unit than the el cheapo ones at walmart. (not 100% sure but, since the airlines have challenged the government for the decoders of A band, I believe they have been released...hence the GPS approachs, ect..ect. Therefore, if you can afford it, you can get extremly accurate readings from GPS units. All in all..you get what you paid for...want to impress your friends..go to walmart...want to impress nonbelievers, go to NASA.
