Okay, in context, I own several GPS units the latest are the Golf Buddy Platinum and my latest the Skycaddie SGX. In this review I am only going to compare the two as they are currently "state of the art" and both current in terms of "top models" from their respective manufactures.
First Looks:- The SGX is thiner than the Golf Buddy and has a better resolution screen albeit a tad smaller graphics which means you need to zoom to get a usable screen. The SGX also has a toggle button which makes the moving to a specific target very easy indeed. The Golf Buddy has a screen which is "less" vivid in term of resolution (think Iphone vs Blackberry) that said, I never really found the Golf Buddy an issue as I'm not going to watch a movie or do some surfing, so I find the extra resolution on the SGX nice but not a clincher. Both come with various extras such as a plastic cradle to wear on the course. Having broken several of the Golf Buddy cradles I bought a leather camera case which works better and you are less likely to lose the unit on the course getting in or out of a buggy or on the green. The main difference between the two is that the SGX is slower than the Golf Buddy and lags behind you in terms of play. If i walk to my ball with the Golf Buddy it simply counts down the yardage as I walk and when I reach my ball I'm ready to play. During that walk, I have decided what club to use and where to play. Using the SGX it shows the last position and then needs time to recalculate your position. This is too often only when you have reached your ball and then it takes up to 10 seconds to update which slows my game and means that I need to spend more time to consider the shot in question. To me this is totally unacceptable as too often you are waiting for the SGX to update and its a bit like playing with a slow player whereby you are always ahead of them. The other main issue I have with the SGX is that even with "Auto Hole" enabled, it just doesn't work so you need to consistently manually update which hole you are on. This requires several key and option selections which again just adds more things that you really don't need to think about on a golf course. This combined with the scoring module is going to get you cautioned by a marshell for slow play. I spent too much time fiddling with the SGX trying to get it to do what I want, rather than playing golf. Its a bit like trying to wake up your caddie each time you want to play a shot!!
Now if you consider that the SGX requires a $156 (GBP99) membership for access to the course data which is free with Golf Buddy, the SGX is a rather hyped and poor second. Also, I just played Desert Willow in Palm Desert CA in 120 degrees and the SGX did not work well in this heat, I had to reboot several times which in my mind is unacceptable.
Another issue is the interface, Skycaddies is web based and Golf Buddy's a program which accesses all the update remotely. I have issues with the Skycaddie's interface which is complex and unreliable. In terms of value for money and performance the Golf Buddy is far better than the SGX but sadly the Golf Buddy lacks the toggle which would make it perfect.
If you are a serious golfer and need to know exact yardage quickly without the hassle then GO GOLF BUDDY, 40.000 courses loaded and free membership is a clincher. The info on the SGX is no better so please don't think you are getting a better product because you are paying, it simpy isnt true. I suspect, you will see my SGX on ebay shortly. Much hyped, but sadly lacking in performance which I blame on poor software and a design team which probably went too far for the units capabilities. So if you read Todays Golfer and see that the SGX is in first place, you will forgive me for thinking if they actually "really" tested the unit and secondly, if ad spend is at play here?
