How Often Should You Upgrade Your Driver?

In this video, Neil Tappin and Joel Tadman ask how often should you upgrade your driver? This is a question many golfers consider, especially as equipment manufacturers produce new models that promise even performance than the previous generation. How much of a difference do these technical developments make to the performance and if you choose not to invest in a new driver for a few years, what exactly are you giving up on? These are the questions that Neil and Joel look to answer in this video.
