What They Have in Common
Both pull from Garmin's 43,000-course database with free yardages (front, center, back) and full-color hole maps. Both support CT10 club tags for automatic shot tracking, PlaysLike distance adjustments, and slope mode. Both use USB-C charging and both require a Garmin Golf membership ($99.99/yr) to unlock green contours. Same app, same ecosystem.
Where They Differ
Device Type and Form Factor
This is the big one. The G82 is a handheld — 308 grams, roughly phone-sized at 3.3 x 6.3 inches. You're holding it, setting it in the cart, pulling it out of your pocket. The S50 is 29 grams on your wrist, 42mm case, 11.4mm thick. That's a meaningful gap — 308g vs 29g is the difference between "thing you carry" and "thing you wear and forget about." For golfers who already don't love managing another device on the course, the watch wins that argument before any spec gets discussed.
The Launch Monitor (G82 Only)
The G82's big swing is its built-in radar launch monitor. You get club head speed, ball speed, smash factor, estimated carry distance, and putting metrics (tempo, stroke length, ball speed). The modes include warm-up, virtual round, target practice, driving range, and tempo training. In radar mode, battery drops to 8 hours, and the device stays stationary while you hit balls — this is range equipment, not something you're running in GPS mode simultaneously. The S50 has none of this. If launch monitor data matters to you at all, the G82 is the only option in this matchup.
Virtual Caddie and Wind Data
The G82 has Virtual Caddie with wind speed and direction via the Garmin Golf app. The S50 has neither. That's not a knock on the S50 — Virtual Caddie and wind data are S70 territory in the watch lineup — but it's worth naming clearly. If you want club recommendations that factor in wind, the S50 can't do that. The G82 can, though it needs an active phone connection for the wind piece.
Smartwatch Features
This flips entirely. The S50 has a heart rate monitor, sleep tracking, fitness profiles, smart notifications, 4GB of music storage, and Garmin Pay. The G82 has none of these. The G82 is a dedicated golf device — it doesn't track your sleep or let you tap to pay for a hot dog at the turn. If you want a GPS that pulls double duty as an everyday watch, the S50 is that. The G82 is a single-purpose instrument.
Battery Life
The G82 gets 25 hours in GPS mode — enough for a couple of rounds before you're reaching for the charger. In radar mode that drops to 8 hours, which covers a solid range session but not an all-day multi-mode situation. The S50 runs 15 hours in GPS mode and 10 days in watch mode. For golfers playing back-to-back days, the S50's 10-day battery means you're not thinking about it between rounds.
Display
The G82 has a 5-inch transflective color touchscreen. The S50 has a 1.2-inch AMOLED. The G82's screen is genuinely large — you can see the full hole layout clearly, read the green map without squinting. The S50's AMOLED is vivid and sharp, better indoors and in shade, but at 1.2 inches you're working with a small canvas. Transflective displays like the G82's tend to be more readable in direct sunlight than AMOLED panels, which can wash out when the sun's high.
Who Should Buy Which
Buy the Garmin Approach G82 if:
- You want a single device that handles both on-course GPS and range sessions without buying separate gear
- Club speed, smash factor, and launch data are part of how you practice
- You play courses where Virtual Caddie with wind data would genuinely change your club selection
- A big 5-inch screen and handheld form factor don't bother you
- You already have a watch you like
Buy the Garmin Approach S50 if:
- You want a wrist-worn GPS you don't have to think about during a round
- Daily fitness tracking, notifications, sleep data, and music are useful to you — not just on the course
- You'd rather spend $200 less and get AutoShot and PlaysLike built-in without a membership
- You're not interested in launch monitor data at all
- Battery life across multiple days without charging matters to you
The Bottom Line
These are genuinely different devices wearing the same brand badge. The G82 is a specialty tool — it earns its $599.99 if you're the kind of golfer who wants to film your range session, track club speed, and have a full-size GPS display on the course. If you're not going to use the launch monitor regularly, you're paying a significant premium for something that'll mostly sit in the cart gathering fingerprints. The S50 at $399.99 is a capable golf watch with AutoShot, PlaysLike, full-color hole maps, and a full suite of smartwatch features baked in. It does the everyday GPS job well. Factor in the $99.99/yr Garmin Golf membership if you want green contours on either — that cost applies to both over time.
