Lately for me I have been working on the driver. My iron play is good, but the driver is where i struggle.

The Driver is also the club that I am inconsistent, my irons saves my game.

does your range have targets or yardage signs? If so, I'd shoot the distances with a rangefinder and use that to get comfortable with specific distances. I'd also suggest using alignment sticks to make sure that your body is properly aligned with your target. Finally, I'd NOT get the large bucket of balls. You don't want to get tired and develop bad habits. Rather, hit the small or medium bucket with a specific purpose.

does your range have a short game area? if so, spend quality time there honing in chipping, pitching, sand, etc. If possible, use your regular balls rather than range balls to gauge how the ball reacts

Practice with a purpose and not just hitting balls. Even after taking a lesson and want to ingrain things.
