One of a host of new swing-reading devices. Swing data from a device clipped to the shaft is sent to an app on your tablet or smartphone. Information on offer includes tempo, swing speed, face angle and the shaft angle at impact.
GM verdict: An impressive tool with detailed information and a clear 3D swing map. This device can also be used for analysing the putting stroke. Another bonus is that is can be used without hitting balls. Bit... it's hard to know what to do with the data without a coach. PGA pro verdict: Some amateurs won't know what to do with the detailed data, but the 3D map is excellent for checking swing plane and studying the swing from different angles.
