Rapsodo MLM2Pro vs. Swing Caddie SC300i Comparison
If you’ve been researching affordable launch monitors, two names keep popping up: the Rapsodo MLM2 Pro and the Swing Caddie SC300i. Both are portable, accurate, and much less expensive than a TrackMan or GC Quad—but they’re built for slightly different types of golfers.
So which one is right for you? I’ve used both myself and have been impressed with the results and will share with you today.
In this comparison, I’ll break down the key differences between these two popular devices, explain the pros and cons of each, and help you figure out which launch monitor fits your game and your practice style best.
Swing Caddie SC300i vs. Rapsodo MLM2Pro Launch Monitor
So, which is better… the SC300i from Voice Caddie? Or, the latest launch monitor from Rapsodo? Let’s start by comparing each to ensure you get the right one for your practice, goals, and budget.
Rapsodo MLM2Pro Launch Monitor
The Rapsodo MLM2 Pro is a more feature-rich launch monitor and simulator designed if you want a lot of data, swing video, and even virtual rounds at home. Once I tested it out in 2024, I was wildly impressed.
Why?
It combines Doppler radar with dual cameras—one to record your swing and another to measure launch and spin—which makes it more advanced than the SC300i.
It pairs with the Rapsodo app on your phone or tablet (there’s no built-in screen) and captures 13 data points, swing video with shot tracer, and supports simulator play with software like E6 Connect. If you practice indoors, the MLM2 Pro performs well as long as you have enough space, and it’s equally solid outdoors.
The trade-off is that it’s app-dependent, slightly less intuitive out of the box, and comes in at a higher price. But if you want video feedback, simulation, and more detailed metrics in an all-in-one package, the MLM2 Pro delivers. It’s a huge upgrade from the Rapsodo MLM, which was one of the first launch monitors in the market.
✅ Pros:
- Dual cameras provide both swing video and ball tracking
- Accurate and reliable across 13 key data metrics
- Works well indoors and outdoors with proper space
- Supports simulation play with E6 Connect and other software
- Video playback with shot tracer makes practice more engaging
- Compact and highly portable for travel or range sessions
🚫 Cons:
- Requires a smartphone/tablet and app to function (no built-in screen)
- For best indoor performance requires at least 8–10 feet of ball flight
- Premium subscription needed to unlock all features of this launch monitor/SIM
- Shorter battery life than the SC300i (about 4–6 hours per charge at most)

Swing Caddie SC300i Launch Monitor
The Swing Caddie SC300i is a portable, user-friendly launch monitor designed if you want accurate feedback without overcomplicating their practice. What makes the SC300i stand out is its simplicity, which I think most golfers need when it comes to understanding data.
This Voice Caddie launch monitors displays carry distance, ball speed, swing speed, and launch height right on its bright LCD screen, no phone or tablet required. This is a massive benefit that most launch monitors do not offer to give instant feedback on every swing.
If you pair it with the free MySwingCaddie app, you unlock additional features like spin rates, session tracking, and swing videos, but even on its own, it’s a great plug-and-play option. The voice feedback feature is also a nice touch for range sessions, letting you hear your carry distance after each shot without having to look at the screen.
The SC300i works indoors and outdoors, is easy to set up, and has excellent battery life. I’m legitimately shocked at how quickly it charges and how long it lasts. You can pretty much keep it in your bag at all times to always get data about your swing.
If you're looking for super-detailed club path or tour-level spin data, this isn't the one for you. But for most players who just want actionable numbers to guide their practice, it’s a fantastic value.
It’s a good upgrade from the SC200 Plus, which is another solid choice from Voice Caddie and easy to see why it made my list of best launch monitors under $500.
✅ Pros:
- Bright LCD screen shows key data without needing a phone or app
- Voice feedback announces carry distance after each shot
- Very portable and easy to set up indoors or outdoors
- Affordable price for the level of accuracy it provides
- Excellent battery life compared to many competitors
- App integration adds spin data and session tracking
🚫 Cons:
- No SIM capabilities like the SC4 Pro
- Spin data is estimated and only available through the app
- Does not measure club path, face angle, or attack angle
- Needs some ball flight to register—not ideal for very tight indoor setups

Closing Thoughts on Rapsodo vs. Voice Caddie
At the end of the day, both devices offer excellent value — it really comes down to how much data you want, whether you’ll use simulation, and how tech-savvy you are.
