Two hundred bucks. Seven hundred bucks. One is a round of golf with a cart and a hot dog. The other is a decent driver.
Both are launch monitors. Both claim to be “launch monitors.” Both claim to give you “real data.” But they’re built for completely different golfers, and the $500 price gap between them isn’t the real story — the real story is what you can actually do with each one.
Based on digging through spec sheets, community threads, and user reviews across both camps, here’s the honest breakdown.
The LM1: $199 of Pure Radar
The Shot Scope LM1 is a Doppler radar unit about the size of a coffee mug. You set it behind the ball, it reads five data points — ball speed, club speed, smash factor, launch angle, and carry distance — and shows them on a built-in LCD screen. No app required. No subscription. No phone. You just hit balls and read numbers.
It’s the cheapest real ball data you can buy. Period.
But here’s the catch: the LM1 is not a simulator. It doesn’t connect to GSPro. It doesn’t connect to E6 Connect. It doesn’t render Pebble Beach on a screen. It’s a practice tool — a really good one for $199 — but it’s not going to let you play 18 holes in your garage in January.
If you want to know your club speed and carry distance at the range, the LM1 is genuinely excellent. The radar is surprisingly accurate for ball speed and carry. Launch angle is approximate (radar estimates it, doesn’t measure it directly). Spin? Not available. Spin axis? Nope. Club path? No. Face angle? No.
Five metrics. That’s the ceiling.
The MLM2Pro: $700 of iPhone-Powered Camera Tech
The Rapsodo MLM2Pro uses your iPhone’s camera (you mount it in the included dock) to capture ball and club data through machine vision. It reads 12+ data points: ball speed, launch angle, spin rate, spin axis, carry, total, club speed, smash factor, club path, face angle, angle of attack, and descent angle.
It also tracks putting and chipping — which is almost unheard of at this price point. Most launch monitors under $1,000 can’t read a 3-foot putt. The MLM2Pro can.
And here’s the big one: the MLM2Pro connects to GSPro and E6 Connect. That means you can play full simulator golf — 43,000+ courses — with the MLM2Pro as your input device. It’s an actual home simulator launch monitor, not just a range tool.
The catch? You need an iPhone. The MLM2Pro doesn’t work with Android. And the indoor accuracy, while good for $700, isn’t camera-purist level. Spin rate can be off by 200-400 RPM on outlier shots. It estimates some metrics rather than directly measuring them.

Which One You Actually Need
Buy the LM1 if: You want to know your ball speed and carry distance at the range. You’re not building a simulator. You’re not trying to play 18 holes on a screen. You just want data — cheap, simple, no app, no subscription, no nonsense. $199. Done.
Buy the MLM2Pro if: You want to build an actual home simulator for under $1,000. You want to play Pebble Beach in your garage. You want putting data. You want club path and face angle to actually work on your swing flaws. You have an iPhone.
These aren’t competitors. They’re tools for different jobs.
The LM1 is the cheapest entry into real ball data — it’s the gateway drug for someone who isn’t sure they care yet. The MLM2Pro is the cheapest entry into actual simulator golf — it’s the gateway drug for someone who’s ready to build.

The Accuracy Question
People ask: “Is the LM1’s radar more accurate than the MLM2Pro’s camera?”
No. The MLM2Pro gives you more data points and more accurate estimates of spin and launch because machine vision captures more information than radar alone at this price tier. The LM1’s radar is good for ball speed and carry (directly measured) but estimates launch angle and gives you nothing on spin.
If accuracy is your obsession, neither of these is your final answer. You want a Bushnell Launch Pro or an Uneekor EYE MINI. But at $199 and $700 respectively, both deliver genuinely useful data for the price. You get what you pay for — and both deliver more than you’d expect.
What Matters
$199 gets you a radar practice tool that tells you five things about your ball. $700 gets you a camera-based launch monitor that reads 12+ data points, tracks putting, and connects to simulator software so you can play 43,000 courses in your garage.
If you’re just practicing: LM1. If you’re building a sim: MLM2Pro.
The LM1 is a great $199 gadget. The MLM2Pro is a real launch monitor that happens to cost $700. Different leagues.
If you’re even remotely thinking about a home simulator, skip the LM1 and go straight to the MLM2Pro. You can read our full MLM2Pro review for the deep dive, or check out our guide to building a simulator under $1,000 for the complete parts list.
The LM1 is the range buddy. The MLM2Pro is the garage buddy. Pick the one that matches your life.
