What They Have in Common
Both run on the Garmin Golf ecosystem, preload 43,000+ courses worldwide, support AutoShot tracking (via CT10 sensors, sold separately), calculate plays-like distances, and require the same $99.99/yr Garmin Golf membership to unlock green contours. Both have USB-C charging, tournament-legal modes, and strokes gained stats.
Where They Differ
Form Factor: Wrist vs Hand
This is the most obvious difference, but it matters more than people think. The S50 weighs 29 grams. The G82 weighs 308 grams. You'll feel that during your swing. The G82 lives in your pocket or cart holder — you pull it out, get your yardage, put it back. The S50 is on your wrist every second of the round, showing you exactly what you need without breaking stride.
If you've ever played a round where you left your cart and had to guess the carry over a bunker, a watch solves that problem completely. Handheld GPS is great at the cart; a watch is great everywhere.
The Launch Monitor — G82's Entire Rationale
This is why the G82 exists. It has a radar-based launch monitor built in — club head speed, ball speed, smash factor, estimated distance, putting metrics (tempo, stroke length, ball speed). Modes include driving range, virtual round, target practice, and tempo training. Battery drops to 8 hours in radar mode vs 25 hours in GPS mode, but that's still a full session.
The S50 has none of this. If launch monitor data matters to you — if you're working on your swing, fitting clubs, or just obsessed with knowing your numbers — the G82 combines a $400+ launch monitor with a $600 GPS device into one $600 product. That math makes more sense than it sounds. If launch monitor data doesn't factor into your practice, the G82's signature feature is completely wasted on you.
Virtual Caddie and Wind Data
The G82 has Virtual Caddie and wind data (pulled from the Garmin Golf app connection). The S50 has neither. Virtual Caddie gives you AI-backed club recommendations factoring in distance, wind, and conditions. Wind data shows speed and direction on-device.
These features matter most on courses you don't know. If you're playing the same three tracks you've played for years, you probably know which club to hit from 150 yards in calm conditions. If you're playing a new course with elevated greens or crosswinds, having a caddie-style recommendation in your hand is genuinely useful. The S50 leaves you making those calls yourself.
Smartwatch Features
The S50 is a proper smartwatch. Heart rate monitor, sleep tracking, Body Battery, Pulse Ox, fitness profiles, smart notifications, Garmin Pay contactless payments, and 4GB of music storage. The G82 has none of these — it doesn't track your heart rate, doesn't notify you of texts, can't play music, and won't tell you how you slept. It's a golf device. The S50 is a golf device that also handles your life between rounds.
Subscription and Green Contours
Same deal on both — green contours require Garmin Golf membership at $99.99/yr. Without it, you get flat green view on both devices. If you're comparing three-year total cost: S50 at $399.99 plus three years of membership runs $699.96. G82 at $599.99 plus three years runs $899.96. If you don't buy the membership, the S50 is $400 and the G82 is $600, and both give you the same green view (flat).
Who Should Buy Which
Get the Garmin Approach S50 if:
- You want GPS yardages without pulling a device out of your pocket
- You care about fitness tracking, heart rate, sleep, or daily health data
- You want music on the course or Garmin Pay for the 19th hole
- You play rounds primarily, not range sessions
- $200 less is meaningful and you don't need launch monitor data
Get the Garmin Approach G82 if:
- You want a launch monitor for range sessions and a GPS for on-course in one device
- You'd otherwise buy both a handheld GPS and a separate radar launch monitor
- Virtual Caddie and wind data are part of how you make club decisions
- You don't mind carrying a 308g device around your neck or in your pocket
- You're serious about practice metrics (swing speed, smash factor, putting tempo) and want them tied to the same ecosystem
The Bottom Line
These two are less "competitors" and more "different tools with the same GPS core." The G82 is built for golfers who practice hard and want launch monitor data and on-course AI coaching in one device. It's priced accordingly. The S50 is built for golfers who want clean, lightweight, always-on GPS with the bonus of a full smartwatch. For the large majority of golfers — playing rounds, tracking scores, improving over time — the S50 does everything you need at $200 less and without adding weight to your bag. The G82 earns its price only if you'd actually use the launch monitor.
Get the S50.
