Full Swing KIT Goes to Baseball

---

Full Swing just did something no other launch monitor company has done. They built a version of the KIT for baseball — and signed two big-league stars to sell it.

Bobby Witt Jr. (Kansas City Royals shortstop, face-of-the-franchise level talent). Brent Rooker (Oakland A’s slugger, All-Star, the kind of hitter every team wants). Marucci Sports — the baseball bat and equipment brand that’s basically the Toyota Camry of the sport — will handle distribution.

And the San Diego Union-Tribune called it “Moneyball 2.0.”

That’s a lot of signal for a product that, until today, was just a golf launch monitor.

The KIT Already Worked for Golf

Full Swing launched the KIT in 2025 as a portable, app-based launch monitor that could hang with units costing twice as much. It sits at the $2,000-ish price point, competes with the Bushnell Launch Pro and the OG SkyTrak, and has been a solid pick for the golfer who wants good data without buying a GC3.

The key architectural detail: the KIT is a Doppler radar unit (not camera-based). That matters because radar-based launch monitors don’t need to sit next to the ball — they sit behind it and track the flight. For baseball, that same sensor architecture can track a 95-mph fastball’s spin rate, exit velocity, and launch angle just as well as it tracks a driver’s ball speed.

So Full Swing didn’t need to invent a new sensor. They took the KIT’s existing three-dimensional tracking engine, pointed it at a baseball, and said “this is a baseball launch monitor now.”

Bobby Witt Jr. and Brent Rooker must have agreed, because they signed on as the faces of the product.

Here’s the full list of what happened, all on the same day:

What	Details
KIT Baseball version	Launch monitor tuned for baseball metrics — exit velo, launch angle, spin rate, pitch tracking
Ambassadors	Bobby Witt Jr. (Royals) and Brent Rooker (A’s) — proven MLB talent, not prospects
Distribution	Marucci Sports — one of baseball’s biggest equipment brands
Press coverage	Forbes, Yahoo Finance, San Diego Union-Tribune, SGB Media, PR Newswire
Sim partnership	Back Nine Indoor Golf (already using Full Swing hardware)

Why This Matters for Golf Sim Buyers

You might be thinking “I’m trying to build a garage sim, not track a curveball. Who cares?”

Fair question. Here’s why this matters to you.

Full Swing just proved the KIT hardware is more versatile than any camera-based launch monitor in golf. Camera-based units like the SkyTrak+, the Eye Mini, and the GC3 all require you to put the unit next to the ball. That’s fine for golf. But it means they’ll never work for baseball, softball, tennis, hockey, or any other sport where the tracking needs to happen at a distance.

Doppler radar doesn’t have that limitation. The KIT tracks objects in flight from behind. That means it could work for any ball sport where you want data on what just left your bat, your foot, or your racquet.

If Full Swing can sell the KIT to baseball players, that’s a broader revenue base. More revenue means more R&D. More R&D means the next generation of the KIT — and the next generation of Full Swing’s sim hardware — gets better, faster. Your garage build benefits from baseball money.

And there’s a more selfish angle. The KIT’s move into baseball signals that Full Swing is thinking about the launch monitor as a general-purpose tracking device, not a golf-specific tool. If the KIT works for baseball, it could work for:

• Tennis (serve speed, spin rate)
• Soccer (shot velocity, ball trajectory)
• Hockey (puck speed, release point)
• Softball (exit velocity, launch angle, same as baseball)

A single launch monitor that covers multiple sports is a product category that doesn’t exist yet. Full Swing is the first company trying to build it.

What the Forums Are Saying

The early Reddit reaction on r/GolfSimulator is split between “that’s cool” and “why should I care about baseball in my golf sim.”

Both are fair.

The “cool” take: a golf tech company just crossed into a mainstream sport with MLB star endorsements and a major distribution partner. That’s a legitimate validation of launch monitor technology as a consumer category. Four years ago, a launch monitor was a niche golf-training tool. Today, it’s expanding into baseball with two MLB All-Stars. The category is growing.

The “who cares” take is also fair because the KIT Baseball doesn’t directly help your golf sim. It’s a separate product for a separate sport. Full Swing isn’t building a baseball mode for the KIT you already own — they’re selling a baseball-specific version of the hardware (probably with different software presets and accessories).

But here’s the counter: Marucci Sports doesn’t partner with a golf company for no reason. They analyzed the baseball training market, saw a gap for affordable launch-monitor-style data, and picked Full Swing’s KIT as the hardware that could fill it. That’s a billion-dollar equipment company’s market research telling you that Doppler radar sim hardware is good enough for professional athletes to train with. That’s not nothing.

The Bigger Story

This is the third major Full Swing announcement in a week.

• July 3: Skill Strike launched — $10K real-money payouts on home sims
• July 4: Back Nine partnership — OEM-franchise deal for sim facilities
• July 5: KIT Baseball — cross-sport expansion with MLB stars

Same day: Full Swing also announced GSPro integration for the KIT and a new gaming platform (Forbes broke the story). KIT GSPro integration → · Gaming platform details →

Three announcements in three days. That’s not random product releases. That’s a company aggressively building a moat.

Full Swing is positioning itself as the most versatile launch monitor company in the world. The GC3 for premium sim golf. The KIT for portable golf data. The KIT Baseball for cross-sport training. Skill Strike for in-home gambling. Back Nine for facility infrastructure. They’re not just a hardware company anymore. They’re an ecosystem.

For the golf sim buyer, the takeaway is simple: Full Swing is investing heavily in R&D, brand building, and market expansion. The GC3 and Pro Series simulators will benefit from that investment. If you’re in the market for a premium launch monitor, Full Swing’s trajectory is worth watching — because they’re building the kind of company that dominates a category for a decade.
