Swing Caddie SC300i vs. SC4 Pro Launch Monitors

If you're looking for a reliable launch monitor, Voice Caddie’s Swing Caddie lineup should absolutely be on your radar. With a reputation for user-friendly tech and portable performance, both the SC300i and the SC4 Pro offer a strong mix of accuracy, usability, and value—but they’re built for slightly different goals.

I've used both and a huge fan as they're easy to use and won't break the bank. Whether you're a data-driven range rat or someone building a home simulator setup, choosing between these two devices can be tricky. That’s where this guide comes in. 

I will break down the key differences, share who each model is best for, and help you decide if the SC300i or the SC4 Pro is the better fit—plus mention why the SC200 Plus still deserves a look for some players.

Both models are featured in our list of the best golf launch monitors under $500, and if you decide one’s right for you, be sure to use code WICKEDSMART for 15% off at checkout.

🎯 SC300i vs. SC4 Pro: What’s the Difference?

On the surface, both units offer a compact radar-based design, voice feedback, and key swing data like carry distance, swing speed, ball speed, and smash factor. But when you dig deeper, and you’ll see that they’re built for slightly different use cases:

• The SC300i is awesome if you want easy-to-use, app-connected performance on the range or indoors—no frills, no complications, just good data.
  
• The SC4 Pro, on the other hand, is a hybrid practice + simulator system, designed to bridge the gap between a traditional launch monitor and a home golf simulator setup.
  

If you're just looking to practice smarter, the SC300i might be all you need. But if you’re dreaming of turning your garage into a virtual golf setup (or want launch data with E6 Connect or OptiShot Orion), the SC4 Pro gives you more versatility—for a higher price.

Let’s dive deeper into each one, starting with the SC300i.

🟦 Swing Caddie SC300i Launch Monitor

The SC300i (updated from the original SC300) is one of the best-performing radar-based launch monitors ever. I bought it years ago and shocked at how consistent it's been in my practice routines.

It offers just enough data to help you understand your swing without the overwhelm. It builds on the success of the original SC300 by adding Bluetooth app integration, voice feedback, and access to more detailed swing metrics via the MySwingCaddie V2 app.

Whether you're working on speed, dialing in your wedges, or just want feedback between lessons, the SC300i provides a highly portable, user-friendly experience. Unlike other budget launch monitors, it doesn’t require Wi-Fi or subscriptions. The onboard screen is large enough to give you key data without needing to constantly check your phone too. 

✅ Pros:

• Rechargeable battery lasts multiple sessions
• Portable, simple, and easy to set up indoors or outdoors
• Measures all the core metrics most amateur golfers need
• Ideal for range work, indoor practice, or coaching sessions
• Syncs with MySwingCaddie app for spin, apex, and swing history tracking 

❌ Cons:

• No simulator support or gameplay integration
• Spin and apex data not shown on the device itself—app only
• No club data like angle of attack or path (expected at this price point)
• App interface isn’t as polished as higher-end systems like Garmin or FlightScope

🟥 Swing Caddie SC4 Pro Launch Monitor

The Swing Caddie SC4 Pro is Voice Caddie’s most versatile and feature-rich model for about $500. It's over that, but when you use the code "WICKEDSMART" you save 15%, making it only $510... an absolute steal!

What's so great is that it offers launch monitor capabilities and simulator functionality in one portable device. While the SC300i focuses on clean data delivery, the SC4 Pro aims to be a do-it-all device so you get data + simulation

It still gives you the core numbers to evaluate each shot like carry distance, swing speed, ball speed, smash factor, launch angle, and apex height—directly on the unit. But the biggest upgrade is the addition of simulator compatibility.

The SC4 Pro can connect with E6 Connect and OptiShot Orion, giving you access to simulated courses and range sessions on a screen. Another standout feature is its built-in camera, which provides video recordings of your swing when connected via the MySwingCaddie app. This adds a layer of visual feedback that’s incredibly useful for self-coaching and reviewing patterns over time.

Whether you're practicing indoors, hitting balls at the range, or simulating a full round in your garage, the SC4 Pro is built to do more—without breaking into premium pricing territory. 

✅ Pros:

• USB-C rechargeable battery with long life
• Extremely portable and user-friendly for the features it offers
• Built-in swing capture camera adds visual feedback via app
• All key metrics (carry, ball speed, swing speed, launch, apex) available directly on screen 
• Includes simulator support with E6 Connect and OptiShot Orion (no extra hardware needed)

❌ Cons:

• No club data (face/path/angle of attack), unlike higher-end systems
• Requires solid indoor setup to get full value from simulator functionality
• App interface and simulator experience not as seamless as premium units
• More expensive than the SC300i (but justified for many by added features)

The SC4 Pro is ideal if you want a launch monitor that can also give you simulator access without investing in a full high-end setup. For serious practice and casual simulator play at home, it punches well above its price—and makes it one of the best hybrid options under $500.

Alternate Pick: SC200 Plus Launch Monitor 

While the SC300i and SC4 Pro offer more advanced features, the Swing Caddie SC200 Plus still holds its own as one of the best entry-level launch monitors under $500—especially if you have never used a launch monitor before. 

The SC200 Plus gives you swing speed, ball speed, smash factor, and carry distance, with voice feedback and remote control functionality. It even includes a Swing Speed Mode that works without hitting a ball—perfect for indoor speed training.

I like to train with Rypstick and it pairs perfectly (same with SuperSpeed or The Stack System). There’s no app, no setup, and no distractions—just reliable data in a lightweight, grab-and-go package.

For beginners, casual players, or anyone focused purely on the basics (especially speed training), the SC200 Plus is still one of the most practical and affordable options on the market.

Closing Thoughts

Overall, I love all of the Swing Caddie launch monitors. After extensively testing all three, I think you can’t go wrong with any of them. It just depends on your goals, budget, and if you want simulation experience or just a launch monitor. 

Voice Caddie has created one of the best launch monitor lineups for golfers who want affordable performance without sacrificing quality. The choice between the SC300i and SC4 Pro really comes down to how you plan to use it:

• The SC300i is perfect if you want accurate data, portability, and app integration to guide smarter practice sessions.
  
• The SC4 Pro is your go-to if you want to practice and play — offering simulator functionality, swing video, and a bit more versatility overall.
  
• And the SC200 Plus? It’s still one of the most underrated tools for speed training and simple practice.
