Losing Distance With Driver

[pganapathy]

Most likely your equipment was wrong for your swing.  As you aged it must have become worse.  You probably needed a different shaft and possibly higher loft.  Just see if replacing the existing driver shaft will be a simpler option

In average we loose a yard each year after.. 30/40. Maybe it get worse around 80/90.
So if you are really seen a loose in distance after a few months is not because of age, it's probably cooler air, less roll because of wet fairways or a swing change that make you swing slower or with worst launch conditions. 

Is always good to check it with trackman and a pro who knows the numbers well. As a scratch player you would think I don't have much room to improve, but last November I was hitting it in average 260(240 carry), always been a short hitter. Hit the trackman with a Pro, change driver, change my club delivery, change my launching conditions and now I'm averaging 280, despite been a year older (39) and going at it with the exact same effort I did las year.
