GARMIN R10: TITLEIST RCT VS METAL DOT! I WAS SURPRISED!

Product reviewed / compared

• Garmin R10 portable golf launch monitor
  • Focus: its latest update compatibility with Titleist RCT balls
• Two ball types used for comparison
  1. Titleist RCT (Pro V1 with embedded metal strips in a “Y” formation to improve radar reading of spin indoors)
  2. Standard Pro V1 with a “metal dot” (a traditional, inexpensive metal marker users can add to any ball)

Main features discussed (Garmin R10 + measurement behavior)

• The Garmin R10 “reads” total spin, but it does not directly measure actual spin axis like high-end camera systems.
• Spin axis is calculated indirectly using other parameters (e.g., club data). This can create differences in shot shape, launch, and spin compared to camera systems.
• The RCT’s embedded metal strips are designed to enable more accurate indoor spin reading than a typical metal dot.

Key test setup & experience

• Tests were performed primarily with an 8-iron.
• The reviewer frequently checks:
  • Total spin numbers (the main metric)
  • Launch angle differences (noted as consistently lower on Garmin for the reviewer than on “overhead units”)
  • Variance across strike types: “normal,” “behind the ball,” and thin strikes
• The reviewer states they keep the unit level, but still sees slightly lower launch on the Garmin.

Results: Titleist RCT vs metal dot (what stood out)

1) “Normal” shots (spin numbers are similar)

• With the RCT, spin values were reported around the mid/low thousands. Examples:
  • 6246 vs 6442
  • 6276 vs 6122 (dot vs RCT example)
• With the metal dot, “normal” shots were also close to RCT values in some cases. Examples:
  • 5841 vs 5934 (and other close matches)

2) Thin shots / miss strikes show more variance with the metal dot

• The reviewer intentionally tries “thin” shots.
• Observed contrast:
  • Thin strike results became much more extreme on the dot, with examples described as roughly ~3000 and later 8000-range comparisons.
  • RCT thin/miss shots showed more consistent behavior. The reviewer describes variances typically as smaller—often around ~100–200 difference when strikes weren’t perfectly crisp.

3) Launch angle + carry differences

• The reviewer repeatedly notes launch angle differences between the two setups:
  • Metal-dot shots showed lower launch, which affects results.
• One cited outcome includes about a ~6-yard carry difference, attributed to launch angle calculation differences between the dot case and the RCT case.
• Direction tendencies are also mentioned (e.g., push vs draw tendencies) on certain shots.

Pros / cons mentioned

Titleist RCT (via Garmin R10)

Pros

• More consistent spin readings, especially on non-ideal strikes.
• Reviewer concludes it performs better overall in their live testing.
• Reported to avoid “wonky” or wildly varying results seen with the dot.

Cons

• Higher cost for RCT balls (which motivates interest in the cheaper metal-dot alternative).

Metal dot (DIY on standard balls)

Pros

• Inexpensive and can be applied to any ball.
• Reviewer saw some close spin matches on good “normal” strikes.

Cons

• Greater risk of larger variance / extreme readings on thin or imperfect shots.
• Proper setup matters: alignment and secure placement are important.

Tips / handling advice for using a metal dot (unique points)

• Some people create a “Y” pattern using metal tape to mimic the RCT style.
• The reviewer emphasizes practical requirements:
  • Must line it up every time
  • Ensure it’s securely attached (won’t tear or cause issues)
  • Avoid scratching turf/screens
• Suggested application method:
  • Push dot/tape on hard (on a soft surface), then roll the ball on a hard surface to smooth/remove sharp edges and improve adhesion.

Comparison to other systems

• The reviewer contrasts Garmin R10 behavior with high-end camera systems:
  • Because R10 doesn’t directly measure spin axis, differences in shot shape versus cameras are expected.
• However, the RCT/dot comparison discussion is framed around how total spin readings behave on the R10.

Verdict / recommendation (based on the video)

• Overall recommendation: If you want more reliable and consistent results on the Garmin R10, especially on thin or imperfect strikes, the reviewer recommends Titleist RCT over a simple metal dot, despite the higher cost.

• The metal dot may be “close enough” on well-struck shots, but the reviewer experienced/observed more variability overall.

Unique points mentioned (consolidated list)

• Garmin R10 is compatible with Titleist RCT after an update.
• RCT uses embedded metal strips in a Y formation to improve radar spin reading.
• R10 measures total spin; spin axis is calculated, not directly measured.
• The R10 tends to show slightly lower launch angle than overhead units for the reviewer.
• On the R10, good shots: RCT and metal dot can produce similar spin numbers.
• On thin/miss shots: the metal dot shows larger variance (including extreme spin readings), while the RCT is more consistent.
• Metal dot may cause carry differences (example cited: ~6 yards), likely due to launch angle differences.
• DIY metal dot concerns: alignment consistency and attachment quality.
• Reviewer’s technique: apply and smooth attachment to reduce sharp edges and prevent scratching screens/turf.
