Your Garmin Watch Is the Missing Piece of Your Sim
Quick Context: If you already own a Garmin launch monitor (R10, R50, G82) and practice in a home simulator, the Approach S70 closes the loop between your garage and the course. It pulls your sim practice data through the Garmin Golf app, feeds it into Virtual Caddie, and gives you smarter club recommendations on real grass. The watch is the bridge, not just a gadget.
You’ve built your simulator. You’ve spent the money, hit the balls, stared at the screen. Your swing is better — the data says so. You’re carrying the ball farther, your face angle is more consistent, your path is less terrible than it was six months ago.
Then you show up at an actual golf course, and none of it matters.
You stand over a 150-yard approach shot with a slight breeze in your face. There’s water left, bunkers right, and the pin is tucked behind a ridge. Your phone GPS says 150. Your brain says “hit an easy 8.” The caddie you don’t have would say “145, knock down 7, aim at the left edge of the bunker.”
You’re standing there, having hit 500 perfect 7-irons in your garage this week, and you literally have no idea what to do.
This is the problem nobody in the home sim world is solving. Every review is about launch monitor accuracy. Every buying guide is about enclosure dimensions. Every forum thread is about GSPro vs. E6. Nobody is talking about the gap between practicing better and playing better.
Garmin, accidentally or intentionally, already built the bridge. It’s called the Approach S70, and if you own an R10 or R50, you’re leaving value on the table by not wearing one. For a full breakdown of the launch monitor itself, see our Garmin R10 review and R50 review.
The Two Disconnected Worlds
Your simulator is great at one thing: giving you data about your swing. Club speed, ball speed, launch angle, spin rate, face angle, path. It’s a lab. You’re the test subject. The numbers are precise and they tell you what you did.
But a golf course isn’t a lab. It’s a 3D puzzle with 18 pieces, and the answer changes every time based on weather, lie, elevation, hazards, and whatever garbage your nervous system decides to do that day.
The data you generate in your sim doesn’t automatically translate to lower scores. It tells you how you’re swinging, not what you should do with it. Those are different skills.
The first skill — swing mechanics — is the one sim owners obsess over. The second skill — decision-making — is the one that actually lowers scores. And it’s the one that’s missing from the entire home sim conversation.
How the Garmin Ecosystem Closes the Loop
Here’s the part that surprised me. I assumed the Garmin Golf app was just a scorecard tracker with some basic stats. It’s not. It’s a centralized database that pulls data from every Garmin golf device you own — your R10, your R50, your Approach watch — and normalizes it into a single profile of your game.
Every shot you hit in your simulator (using the Garmin Golf app’s built-in sim features or Home Tee Hero) gets logged. Every shot you hit on the course with your Approach watch gets logged. Both live in the same profile, under the same Garmin Golf account.
This matters because of Virtual Caddie.
Virtual Caddie is the feature on the Approach S70 that recommends clubs. It works like this: after you’ve played a few rounds with club tracking enabled, it knows your real distances. Not your claimed distances. Not “I hit my 7-iron 160 when I really catch one.” Your actual, statistical average distance with each club, based on the shots you’ve hit on actual courses.
But here’s the part I didn’t realize until I dug into it: that distance profile gets richer the more you use it, and it pulls from every data source connected to your Garmin Golf account. Sim sessions count. Range sessions count. On-course rounds count. Every swing you take, in any context, feeds the same model.
The watch then takes that profile and adds environmental variables — wind, elevation, temperature — to give you a specific club recommendation for the exact shot you’re facing. It’s not guessing. It’s calculating, based on your actual data, what club gives you the highest probability of hitting the green from that spot, with those conditions.
The Feedback Loop That Nobody’s Marketing
Here’s why this matters for sim owners specifically.
When you practice in your sim, you’re generating data about your swing mechanics. When you play on the course with your Approach watch, you’re generating data about your decision-making and outcomes. The Garmin Golf app connects these two data sets into something bigger than either one alone.
Practicing in your sim improves your swing. Using Virtual Caddie on the course improves your decision-making. Your distances get more accurate. Your dispersion patterns get tighter. You stop guessing and start knowing.
Then you take that knowledge back to the sim and work on the weaknesses the data identified. Your wedge game is costing you strokes? Work on wedge distance control in the sim. Your driver dispersion is too wide? Tune the swing, then go verify on the course. Repeat.
This is the feedback loop that every home sim owner needs but nobody is selling. The hardware manufacturers sell you a launch monitor. The software companies sell you a simulation. Neither of them sells you a system for turning practice into lower scores.
Garmin doesn’t market this as a feature either, which is honestly baffling. They sell the S70 as a premium golf watch with a pretty screen (which it is). They sell the R10 as an affordable launch monitor for home practice (which it is). They sell the Garmin Golf app as a scorecard tracker (which it also is). But they don’t connect the dots for you. They don’t say “buy all three and you get a closed-loop practice system that makes you measurably better.”
That’s the value of the ecosystem, and it’s the piece every standalone review misses.
Which Watch Should You Buy?
If you’re a sim owner considering the watch, the lineup breaks down like this:
Approach S70 ($650-$700): Full Virtual Caddie with environmental adjustments, green contour data, wind data, shot dispersion mapping. The 1.4-inch AMOLED display is genuinely beautiful — readable in direct sunlight, which matters more than you’d think. This is the one that gives you the full feedback loop. The 47mm version has the best battery — about 20 hours of GPS, which covers four rounds or a week of daily wear. Buy this one if you take your game seriously.
Approach S50 ($400-$450): Gets you Virtual Caddie and PlaysLike Distance with a Garmin Golf membership. You miss the wind data and some of the more advanced environmental adjustments. The AMOLED display is smaller (1.2 inches). Still connects to the same ecosystem, still feeds the same data profile. Buy this one if you want the loop but don’t need the premium screen.
Approach S44 ($250-$300): Basic GPS with AutoShot tracking. You don’t get Virtual Caddie at all — no club recommendations, no dispersion analysis. You still get your shot data flowing into the Garmin Golf app, but you lose the decision-making layer. Buy this one only if you want a cheap course GPS and don’t care about the intelligence features.
For a sim owner, the S70 is the right answer. The Virtual Caddie is the feature that closes the loop. Without it, you’re just tracking data. With it, you’re getting actionable decisions.
What Everyone Else Is Missing
The competitor reviews of the Garmin Approach S70 all follow the same script: nice screen, good battery, accurate GPS, expensive. They treat it as a standalone gadget. A premium GPS watch for golfers who want to spend $700.
What they don’t ask is: what does this connect to?
The answer is: everything else Garmin makes. The R10 in your garage. The R50 in your sim room. The Garmin Golf app on your phone. The 43,000 course maps in their database. The Home Tee Hero subscription on your tablet.
It’s not a watch. It’s the wearable interface for an entire golf ecosystem that starts in your garage and ends on the 18th green. The watch is the piece that connects your practice to your scoring, and that connection is the most underrated feature in the entire Garmin lineup.
If you’ve already got a Garmin launch monitor, you’re halfway to a closed-loop system. The watch is the other half. Go buy it.
