About 8 years ago I wanted to figure out how to get more length, more consistency and maybe extend my swing (besides the obvious of being skinnier lol). Went for my first lessons ever, bought a 3 lesson deal from a really good pro up here in WesMass. I will put it this way never went back to the 2nd and 3rd. After an hour of him thinking of changing a few things I was very uncomfortable with change. We only worked on a 7 iron for an hour and the big change was the take back target which seemed to me to be too far out of line although I know he is correct. I took a little from that lesson but didn't want any more thoughts because I wasn't ready to shoot a few 90's before getting it right, too much money and bragging on the line with my buddies so I am settling for who I am but wished I had done it earlier. I had played for 35 years or so as a baseball player turned golfer. I can shoot 70-85 not always knowing what swing will show up honestly but I'm good with that rather than begin a swing change at about 52-53 years of age it was too late at that time. But for those who want to improve and bring it to another level it IS the way to go. Patience is a must as they will ask you to do things which seem perplexing but will eventually lead you to being a better ball striker. Go for it and good luck you will get there!! Great game.
I took lessons as a teen. Had some natural length off the tee with a slight draw. Still recall my dad telling me to hit away as there was a lawn mower in the fairway pretty far out, tee shot bounced off the roof. Driver, 3 hybrid, putter and sand wedge I’m decent. Suck with everything else. Kind of the opposite of the average duffer.
When I played semi-regularly in law school with my roommate, who was a college golfer I got to the mid-high 80s. But even that wasn’t every week. Now I play maybe 6-8 times a year. Would lessons help? I don’t get enough repetition in to create consistent swings. I average high 90s and if I play slightly more regularly I can drop that to low 90s. I‘m usually all over the place. Eagle, triple bogie, par, double bogie. I can drop my score if I play “smart golf”, but I love the challenge of making the impossible shot.
My 80 year old dad still sometimes shoots in the 70s. He won a course championship in his early 60s from the back tees against the younger guys. But when you park your cart in your garage and play 5 times a week, 52 weeks a year you dial that stuff in.
So for lessons, I’d say yes if you are new or your swing is highly flawed. Yes if you can play enough to develop the muscle memory and need the help. In your situation or mine, nah.
