On The Mark: Discussing How FlightScope’s i4 Rangefinder and Data Insights Elevate Every Shot

In a compelling episode of the On the Mark podcast, FlightScope founder and CEO Henri Johnson joined host Mark Immelman to explore the science and inspiration behind FlightScope’s cutting-edge technology – particularly the latest game-changing i4 Laser Rangefinder.

Johnson emphasized that understanding ballistics and leveraging accurate data is no longer reserved for professionals. These tools are now accessible to all golfers looking to improve not just performance but confidence on the course.

The i4 Rangefinder is Born

The i4’s development was sparked by a revelatory moment during a Genesis Invitational practice round at Riviera with Bryson DeChambeau and Tiger Woods. Both players pulled their “200-yard club” on a par-3. Tiger’s shot finished just three yards short, safely on the green. Bryson’s landed 13 yards short – well off target.

"I came to the rescue and said, 'Bryson, I think there's something in the air. There's something going on here,'" Johnson recalled. This observation propelled him into deep calculations, even starting to write software on the plane back home. 

His analysis revealed that atmospheric conditions – specifically increased air density at sunset – had amplified the drag and lift forces on Bryson’s ball. With his higher spin rates and ball speeds, the environmental factors had a more pronounced effect, causing the shot to go higher and shorter.

"Nobody knew what the conditions were at the time in terms of the air density and what we call kinematic viscosity," Johnson explained, highlighting that even at the highest levels of the game, the complex interplay of physics and environmental factors is often not fully understood. 

This realization solidified FlightScope's mission: to provide golfers with the clarity needed to make informed decisions, transforming guesswork into confident execution. And thus, the FlightScope i4 Laser Rangefinder was born.

The i4 Rangefinder: A Personalized Caddie in Your Pocket

The FlightScope i4 is more than just a rangefinder – it’s an advanced AI caddie. By leveraging aerodynamic data from each club’s launch conditions, the i4 uses complex optimization algorithms to suggest the best club for every shot based on your personal club gapping. It also factors in real-time local weather conditions, such as wind speed, direction, and target height, ensuring each recommendation is tailored to the golfer’s current environment.

When you use the i4, you get:

• Direct Distance: The precise line-of-sight distance to your target.

• Effective Playing Distance: This is the game-changer. The i4 pairs with the FS Golf app on your phone, pulling local weather data (temperature, pressure, humidity, wind speed, and it allows you to select wind direction as well). It then calculates how far the shot will actually play for your specific club gapping, providing a personalized "effective playing distance." This means you'll know exactly what yardage to consider, as if you were at your home course.

• Recommended Club: The i4 confidently suggests the ideal club to hit, based on your effective distance and personalized club gapping data.

To make this personalization seamless, the FS Golf app offers flexible ways to input your club gapping data:

• Smart Gapping: A revolutionary AI powered feature that requires only one mid-iron's carry distance, your home location, and the clubs in your bag to accurately calculate the gapping for your entire bag, leveraging FlightScope's extensive ballistics databases and AI. "It's scary how accurate that is," Johnson noted. Mark Immelman affirmed, "That's the smart gapping, and it is really smart."

• CSV Import: For users with data from the FS Golf PC Software or other launch monitors.

• FlightScope Session Import: For FlightScope users, allowing for quick and precise import of previously completed gapping sessions.

Johnson emphasized the impact of this feature: "When you’re confident in your distance, you remove doubt – and doubt is never good with a golf club in your hand.” Immelman agreed, adding – “Doubt is the biggest swing wrecker in the world." 

The i4 fosters confidence, leading to better execution and, ultimately, lower scores and more enjoyment on the course. "If you start using the i4 laser rangefinder your golf will improve, because knowledge is power,” Immelman added.

Data and Confidence in Practice and Play

Beyond the i4, Johnson highlighted the broader philosophy of FlightScope, emphasizing the importance of accurate data for game improvement. He underscored how understanding foundational concepts, such as face impact location and swing path relative to the target, can revolutionize a golfer's practice and on-course decisions.

Johnson recounted how Immelman’s daughter, Izzy, uses a FlightScope launch monitor in their garage to warm up for tournaments. By projecting the FS Golf app screen onto a net, she monitors her swing path within her "cone" and ensures consistent ball striking on the sweet spot. This practice, guided by precise data, has transformed her game, preventing the development of bad habits and fostering unwavering confidence.

“Any athlete practicing in a misguided way will find it hard to improve,” Johnson explained. “Accurate feedback on fundamentals is essential for long-term growth.”

Immelman agreed: “I wouldn’t practice without a launch monitor measuring D-Plane data. We might get the ball to the target, but if we’re doing it the wrong way, we’re just ingraining bad habits.”

They also discussed how understanding subtleties like club path, face angle, and angle of attack helps golfers avoid unnecessary or harmful adjustments.

"Knowledge is really important, but what is more important is to understand what matters most," Johnson advised. This insight is where a coach's guidance, combined with precise data, truly empowers golfers. 

FlightScope: A Legacy of Accuracy and Innovation

Johnson's journey into golf technology began with a deep background in ballistics, developing radar systems to track projectiles fired from guns, with accuracy demands within 1%. This expertise became the foundation for FlightScope's renowned precision in golf.

“I’ve tested every system out there,” Immelman said. “FlightScope’s data is the most accurate in the industry. I’ve been a believer from the start.”

From the early days of designing systems for cricket and tennis, FlightScope transitioned into golf in the year 1997, driven by a desire to measure club and ball speed. Today, FlightScope offers a comprehensive range of launch monitors, from the entry-level Mevo, to the Mevo+ with its Pro Package and Face Impact Location software add-ons, and the flagship X3C.

"This company is ever-evolving,” said Immelman. “You guys are never standing still. I mean, when I go to your website there's always something new." 

This relentless innovation ensures FlightScope stays at the forefront of golf technology – bringing tour-level insights to everyday players.

Confidence Breeds Confidence: The FlightScope Promise

The core message from Henri Johnson is clear: FlightScope's technology is designed to eliminate doubt and build confidence. Whether it's the personalized effective distances from the i4 Rangefinder or the precise data insights from a FlightScope launch monitor, these tools empower golfers to make informed decisions and execute shots with greater assurance.

“FlightScope provides the exact data needed to simplify decision-making,” Immelman concluded. “Use it consistently, and you’ll start making better choices instinctively.”
