When I was introduced to the Shaft Lean Alignment Aid, I was amazed how easy it was for myself and students to use this aid for Shaft Lean at address and what is key also at impact. The Shaft Lean Alignment Aid can go on your Irons, Woods and Wedges; it can also go on your Putter. Putting is often a forgotten part of the game, and this aid takes the guess work out of the putting. As a PGA Teaching Professional, the functionality of the Shaft Lean Alignment Aid is so simple to use. It is easy to install and is USGA Approved unlike most teaching aids. You play with it you practice with it on your club all the time and is easy reminder of what your address position will be every time.

I personally tried the Straightline and as a golfer instructor I feel that it’s a great advantage to lowering a golfer’s score. It aligns the club to duplicate the same setup each time, this achieves the perfect swing. I feel that this is the future of golf and highly recommend this for your set of clubs to help lower your handicap!!

I've been teaching golf for over 20 years. The Shaft Lean Alignment Aid is one of the easiest ways to understand the importance of forward shaft lean at impact. This is a great training aid for beginners and intermediate golfers to improve ball first contact and work on improving their game. It's simple and effective
