At £299.95 it’s not cheap. After all you could have your choice of drivers for this kind of money. But I would lay a £10 bet that you would save more shots on your next round with SkyCaddie in your hand, than a new driver in your bag! http://www.skygolfgps.com/.
The only potential drawback is that your playing partners will start asking you for distances from around the 2nd hole until the end of the round – Tell them to get their own!
