Is the UDisc GPS accurate? Also, how accurate are the signs at blue ribbon pines?
I use UDisc all the time. I can't speak for certain as to the accuracy of it, but if the signal I get using my iPhone for Geocaching is any indication of how on point the GPS is, I'd say it's pretty close.
IMHO -- and I am in no way affiliated with UDisc or their distributors, nor am I a paid proponent -- UDisc is far and away the best DG app on the market. Best two-bucks you'll spend for disc golf.
