There are two kinds of golfers.

Those who want to play golf.

And those who lie awake at night wondering why their 7-iron suddenly hates them.

Tee Box San Marcos has something for both.

The new indoor golf and training facility celebrated its grand opening Saturday, Aug. 22, at 1619 S. Rancho Santa Fe Road — complete with food, games, contests and giveaways.

Now the balloons are gone.

The doors, however, are very much open.

In fact, Tee Box is built around 24/7 access.

And once you see what's hiding inside, you understand why calling this place a "golf simulator" doesn't really cover it.

Four Bays. Thousands of Swings. No Lost Balls.

Let's start with the toys.

Tee Box San Marcos has four TrackMan simulator bays.

If you've never used TrackMan, think of it as the world's least sympathetic golf buddy.

You swing.

It measures.

Ball speed. Launch. Flight. Club data.

There are no excuses about the wind. No blaming the grass. And unfortunately, "I think I hit that pretty well" is now something that can be fact-checked.

But that's also the point.

Golfers can use the technology to see what's actually happening with their swing, practice specific shots and track improvement instead of endlessly pounding balls and hoping for a breakthrough.

And because it's indoors, darkness doesn't get a vote.

Neither does the weather.

Then There's the Putting Green

This might be the coolest part of the place.

Tee Box has a PuttView green that projects information directly onto the putting surface.

Break.

Target.

Ideal line.

Right there on the green.

It's essentially giving you the answer sheet before the test — although you still have to make the putt.

Scramble Kings Golf, which attended the grand opening, also highlighted the facility's games as a way for parents to practice while keeping kids entertained and introducing younger players to golf.

That's a pretty smart combination.

Because "Dad wants to practice his swing for two hours" isn't traditionally a sentence that sends children sprinting toward the car.

Here's Where Tee Box Gets Interesting

The simulators may get your attention.

But they're not really the whole business.

Tee Box is trying to build something closer to a training center for golfers.

The San Marcos facility promotes personalized golf and fitness coaching, golf-specific strength training, club-fitting consultation and monthly leagues.

There's even a gym inside.

So you can work on the swing.

Work on the body making the swing.

Check whether the clubs are helping the swing.

Then go back to TrackMan and discover the swing still has opinions of its own.

Golf is a humbling sport.

And Yes, It's Open at 2 A.M.

Here's another thing that makes Tee Box unusual:

The San Marcos location is listed as open 24 hours.

That's a pretty dramatic departure from traditional golf.

No scrambling to squeeze in nine holes before sunset.

No range closing just when you've finally figured something out.

For members with the appropriate access, Tee Box's grand-opening materials advertise 24/7 simulator and gym access.

Early bird?

Go hit balls.

Night owl?

Go hit balls.

Can't sleep because you're still thinking about the three-footer you missed Saturday?

You may have found your people.

San Marcos Has a New Kind of Golf Spot

Indoor golf isn't replacing the real thing.

That's not the point.

What Tee Box brings to San Marcos is another way to experience the game — one built around practice, technology, fitness and convenience.

The grand opening ran from 3 to 6 p.m. on Aug. 22, but the facility is now officially up and running at 1619 S. Rancho Santa Fe Road in San Marcos.

Tee Box is also promoting free "Box Assessments" for golfers interested in evaluating their game and seeing how its training system works.

Will any of this finally fix your slice?

We make no promises.

But when you've got four TrackMan bays, professional coaching, a gym and a putting green that literally shows you the line...

you are officially running out of excuses.
