Garmin Approach S50 vs Voice Caddie T11 Pro

The Quick Verdict

Get the Garmin Approach S50. For most golfers, it's the safer, more complete watch — better ecosystem, USB-C charging, proven durability, and a 29g weight that disappears on your wrist. The T11 Pro is a real contender if you want green contours and wind data without paying Garmin's $99/yr membership fee, and you don't care about fitness tracking. That's a narrower case than it sounds, though. The S50 does more, costs $50 more, and is the one I'd put on my own wrist.

What They Have in Common

Both are touchscreen AMOLED/OLED watches with full-color hole maps, 40,000+ preloaded courses, automatic shot tracking, hazard distances, scoring, no mandatory subscription, and one-year warranties. Both handle slope adjustment and run a 10-day watch battery. You'd be fine on the course with either.

Where They Differ

Green Contours & Putting

This is the T11 Pro's strongest argument. At $349, it includes green undulation data, slope direction arrows, a long-putt aim guide, and uphill/downhill indicators — all with zero membership fee. Garmin charges $99.99/year for green contours on the S50. If you play 30+ rounds a year and care about reading greens from your wrist, that math is worth doing: the T11 Pro pays for itself versus an S50-plus-membership in about 18 months.

The Smart Putt View on the T11 Pro is genuinely unusual at this price. It's not just "slopes exist here" — it tells you aim left or right on long putts and reads the terrain between your ball and the pin. That's the kind of feature you'd expect from a $500+ watch.

The S50's green view is flat. You get front/center/back distances and a bird's-eye layout, but no slope data unless you subscribe. Call that a significant omission for golfers who use their watch to replace a caddie's read.

Virtual Caddie & Wind Data

The T11 Pro has V-AI 3.5, which gives you automatic slope calculation, club recommendations, and wind direction with speed. The S50 has neither a virtual caddie nor wind data — those live on the Garmin Approach S70 ($599).

If you've never had wind data on a GPS device, you might not miss it. But once you're used to glancing at your wrist before a par-3 over water and seeing "12 mph into," it's hard to go back to guessing.

Fitness & Smartwatch Features

The S50 is a full fitness watch. Heart rate monitor, sleep tracking, Body Battery, Pulse Ox, fitness profiles, contactless payments (Garmin Pay), and 4GB of music storage. If you use a watch 24/7 and want it to double as a training and wellness device, the S50 does all of that without any additional hardware.

The T11 Pro has smart notifications. That's it. No heart rate, no sleep, no music, no payments. It's a golf watch that happens to sit on your wrist between rounds, not a fitness tracker that happens to play golf. That's not a knock — some golfers specifically don't want their Strava data next to their handicap — but it's worth knowing going in.

Weight & Build

The S50 is 29g with the nylon ComfortFit band, which is genuinely light. The T11 Pro is 48g, which is still reasonable but noticeably heavier — about the weight of a typical sports watch. Neither is a problem; the S50 just has an edge for golfers who are sensitive to wrist feel during the swing.

The S50 is rated 5 ATM (water resistant to 50m). The T11 Pro's water rating isn't published. That's an odd omission for a watch marketed to outdoor use, and it matters if you're playing in rain or rinsing your hands at the water cooler mid-round. I'd want an answer from Voice Caddie before wearing this in wet conditions.

The S50 charges via USB-C. The T11 Pro's charging method isn't specified — probably proprietary, but that's unconfirmed.

Who Should Buy Which

Get the Garmin Approach S50 if:

• You use your watch off the course for fitness tracking, sleep, or workouts and want one device that does everything
• You don't putt using a watch — the flat green view won't matter if you already have a green-reading routine
• You're already in the Garmin ecosystem and your phone, bike computer, or trainer speaks Garmin
• You want music on the course without your phone
• You're playing courses in remote or international locations where course database depth matters

Get the Voice Caddie T11 Pro if:

• Green contours are something you'd actually use and you don't want to pay $99/yr for them
• Wind data on your wrist would change how you play — this is one of few mid-tier watches that includes it
• You want a pure golf watch and have a separate fitness tracker or don't care about health monitoring
• You're comfortable with a less-established brand and can live without confirmed water resistance specs

The Bottom Line

The S50 is the more complete device. It's lighter, charges via USB-C, has confirmed water resistance, plugs into a mature ecosystem, and doubles as a legitimate fitness tracker. The T11 Pro punches above its weight on golf-specific features — green contours and wind data at $349 with no subscription is legitimately impressive — but it gives up a lot on the lifestyle side.

For most golfers buying a GPS watch in 2025, the S50 is the right call. If you're a committed one-device-for-golf-only buyer who reads greens carefully and watches wind, the T11 Pro is worth the look. Otherwise, spend the extra $50.
