TESTERS ANNOUNCED! SKYCADDIE SX400 GPS in TESTERS WANTED Posted December 14, 2019 Charlie DeVerna Long Island/Pinehurst,NC Garmin G20 If you don't have a swing/stroke, technology means very little. However if you do, especially with clubs versus putter, tech helps for sure. Regarding GPS, I am not in love with what I am using. I also think if you play alot of different courses, good GPS helps with distance(s) and flag locations alot.Definitley an advantage and will save a few strokes per round.
