Golf has experienced significant growth in the launch monitor market. While some units can cost over $20,000, there are also many affordable options available for under $1,000. In 2023, Voice Caddie released the SC4 launch monitor, followed by the highly anticipated SC4 Pro in late 2024. When it launched, THP provided an overview of what to expect. After spending more time with the device, we’re ready to share a deeper look at our experience with the SC4 Pro.

Take the SC4 Pro outside!
Driving range sessions can become monotonous, but one way to enhance those practices is to incorporate a personal launch monitor to provide instant feedback. With the SC4 Pro, Voice Caddie is vying to be that companion, providing audible feedback on how good, or not so good, your range session is going.
Setting up the SC4 Pro at the range is relatively easy. First, use the built-in kickstand to position the device about 5 feet behind the ball, ensuring it is aligned with the direction you plan to hit. A helpful feature for alignment is the red line on the top of the unit.
It’s also important to ensure that the SC4 Pro is the same height as the ball. While this isn’t much of an issue when hitting off the grass, using driving range mats can create some challenges. To address this, Voice Caddie offers a height-adjustable tray that can be purchased separately. Although it may not be the most visually appealing accessory, it effectively serves its purpose.

Once everything is set up correctly, it’s time to decide how you want to practice. The simplest way to begin is to power on the device and switch it to practice mode. Grab the remote control, which allows you to change the club selection, adjust the loft, and start hitting balls. After each shot, you’ll hear an audible readout of the distance(yes, there is volume control). Hopefully, the shot was good because once it starts announcing your numbers, you’ll likely draw some attention from other members at the range.
If you’re looking for more detailed data, check out the 4.8-inch LCD screen. It displays additional metrics such as launch angle, launch direction, swing speed, ball speed, apex height, smash factor, and spin rate. This LCD screen provides a significant advantage for the SC4 Pro compared to some of its competitors and comes in handy for those days when connecting to an iPad isn’t in the cards.
For a more focused practice session, Voice Caddie features a target mode, which is one of my favorites. Using the remote, you can switch to target mode and select your desired distance for upcoming shots. This mode is particularly enjoyable when at the range with a practice partner, allowing for a competition to see who can get closest to the target yardage.
Moving Inside
When setting up the SC4 Pro indoors, there are several recommended procedures to follow. Like with an outdoor range, it is best to position the launch monitor approximately five feet behind the ball. To ensure accurate data collection, maintain a distance of at least ten feet between the ball and the net or screen. Once again, ensure the SC4 Pro is level with the ball and appropriately aligned with your target.

Our testing found that using a setup closer to the net produced inconsistent results, so allowing for the necessary space is crucial. When we increased the distance between the ball and the net, the data we collected aligned more closely with the readings from our SkyTrak+ launch monitor.
Among all the data points collected, the backspin showed the most variation between the two devices. Generally, the backspin numbers from the SC4 Pro were higher than those from the SkyTrak+. However, despite this difference, the carry yardages were consistently similar.

The SC4 Pro has an additional feature for indoor play: it connects to the E6 golf simulator software. When you purchase the SC4 Pro, you’ll receive a registration card granting access to five courses on the E6 platform. Those included courses are Aviara Golf Club, Bandon Dunes Golf Resort, Sanctuary Golf Course, Stone Canyon Golf Club, and Wade Hampton Golf Course.
We tested the connection between the SC4 and E6 on both an iPad and a Windows PC, and it connected quickly in both cases. However, it’s worth noting that E6 employs a bind and unbind license process. This means that if you plan to switch devices, you’ll need to go through a somewhat cumbersome process, which is more of an issue with E6 than with Voice Caddie.
Once in the app, golfers can choose to play an 18-hole round on one of the available courses or set up a specific hole to practice. The gameplay experience while connected to the SC4 is smooth and fast, making it a great option for those looking for an introduction to indoor golf.
VoiceCaddie S App
Regardless of where the SC4 Pro is set, golfers will want to download the VoiceCaddie S app. Here, we see all of the new additional data metrics that put the Pro in SC4 Pro. These additional data points include spin axis, side spin, backspin, and dispersion. Once you’ve downloaded the app, the entire SC4 Pro experience significantly changes.

Graphically, the new 3D driving range impresses on an iPad. There is a slight delay from the moment the ball is hit until it shows up on the screen, but the playback is smooth as the users will see the entire ball flight come to life. Other driving range features include the ability to set a target, switch between top and side views, and customize the data points that are of particular interest to you.

One often overlooked feature of the app is the ability to revisit shots taken during previous sessions and to view the replay of specific shots. While this may not resonate with every golfer, as a club reviewer, it is valuable. It’s helpful to go back and analyze not just the data but also the visual representation of the ball flight. This is just one example of how Voice Caddie has made a strong effort to create a useful and informative app for golfers. The best part? No subscription fees are required for the app, which is a notable factor to consider when comparing it to other personal launch monitors.
Swing Speed Mode
The Voice Caddie S app also features a swing speed mode that performs well both indoors and outdoors. This mode is ideal for golfers looking to increase their swing speed or those wanting a better understanding of their clubhead speed.

During our experience with the SC4 Pro, we tested this mode by taking dry swings with a driver. The app records the current speed during each swing and also tracks your daily average, best daily performance, and your fastest overall swing ever recorded. All of this data is clearly displayed within the Voice Caddie S app, allowing users to easily monitor their progress over time.
It’s important to note that you do not need to hit a golf ball while in swing speed mode. You can also use any club or speed training product, such as the weighted clubs from SuperSpeed Golf.
Final Thoughts – Voice Caddie SC4 Pro
With the SC4 Pro, Voice Caddie is bringing a lot to the table to help golfers improve and understand their game at a price that doesn’t break the bank. Is it perfect? No, but when talking about any launch monitor in this price range, there will inevitably be some trade-offs. That said, the SC4 Pro is a very capable and competitive unit when looking at others in the market in this price bracket. Those looking for a device that can bring some extra enjoyment to a range session or serve as an entry point into indoor golf would be wise to take a serious look at what this device offers.
Voice Caddie lists the SSC4 Pro on their website for $599.99, but at the time of this writing, they are knocking $50 off, making it $549.99. Truth be told, it would be wise to take that $50 savings and invest it in the case. Not only will the case keep it safe, but it can also help level the device when hitting off a range mat sans the height-adjustable stand.

More information on the Voice Caddie SC4 Pro launch monitor is available at www.voicecaddie.com.
I’ve been curious about this one. I have something of a love/hate thing with my R10. Ultimately, I think if I were to get something new I would go up a price class for a bigger player, but this seems like it could be the winner in this price bracket at this point. What type of club data does it include? Any path or face angle metrics?
Thank you [USER=782]@ddec[/USER] for that write up. I had the Voice Caddie SC 200 and enjoyed it but quickly became bored with it. I like the SC4 Pro and the extra features it brings to the table. As someone who practices more than I play, this is perfect for keeping my range sessions fun and not feel like I am just hitting balls with no purpose.
Good stuff, [USER=782]@ddec[/USER] ! This one intrigues me, and it looks pretty promising, especially at the price point listed. Having something like this might actually entice me to go to the range and practice more.
If you want a low cost option this sounds like it should be it. I have a SC200 I take to the range with me still, but having other data points would be useful when trying to dial in, plus the addition of speed training is nice.

I think it’s a fun thing to take to the range, especially if you aren’t going to hook up to the app at that time. It’s small enough to fit in the bag and without the app, takes about 15 seconds to set up.
Nice write up [USER=782]@ddec[/USER] I really like that this is small enough to throw in your bag and take to the range, if you’re so inclined. The fact that you can connect it to a home sim and play with no subs makes this a good lower cost option for a lot of people.

I had one of those too. This definitely offers other ways to stay motivated to use. I’m hoping they can build up the Voice Caddie S app a little more down the road, but for now there’s some good basic range and target practice. Enough to make you feel you are getting more out of your range session if you want.
What do you think about the data indoors? Did you test with any RCT balls?

The no sub is huge. Think about it. Price wise it’s really head to head with something like MLM2 pro. It doesn’t have the camera that MLM2 has, which is a cool feature. Instead you get the on board screen. But you don’t need RCT balls and the sub for MLM2 to get into the course play is something like 200 a year or 500 lifetime? Those numbers could be off, I’ll admit that, but you get the point.
VC has talked about adding other sim software partners. That would be cool to see down the road.

I did not go grab any RCT balls as they aren’t required. Indoors, I guess outside too, but definitely need to make sure you have things setup right or else you might not see the shot direction you expected. Get everything the same height and the data Id say is passable. There were times when the launch and spin combo seemed slightly off(example being higher spin with lower launch), yet the carry numbers and flight direction were really close to what I was seeing on ST+. Do I think it was as accurate as one of the higher end units…I don’t. But again, being at this price the expectations need to be in the right place.

You mention you can use an iPad. Can you have that set up on the range with the device and see the ball flight in real time? I think the article reads that way, but not 100% sure.

Yeah for a range unit this seems phenomenal
I remember the original came out the same time at the mlm and didn’t fare so well.
I have high hopes for the updated version because the onboard data and not needing a separate screen of device is a winning combo

You certainly can. It changes the screen to “sim” mode, which turns off the data on screen and the audible readings. Can easily bring a tripod and set the iPad next to you so it’s not that big of a deal to lose that.

I think that’s exactly what it has going for them when talking about the competition which is basically r10 and MLM2.

I’ll also say, with the way indoor setups vary from space to space, that *could* have an impact too.
[USER=782]@ddec[/USER] is the swing speed hidden behind a paywall or subscription?

No subscriptions with this guy
[USER=15992]@MikeG[/USER] One other point…if you are using the iPad at the range, I’d make sure to hook it up to wifi or hotspot your phone. That way data syncs and you can see everything later.
[QUOTE=”ddec, post: 13075063, member: 782″]

Yeah the mlm days are limited I will pick this up when the subscription is up
Great write up [USER=782]@ddec[/USER]! I’ve got a friend who recently picked up the SC4 Pro and for the price has been really impressed. I’m hoping to add something like this to my arsenal for next offseason when I’m stuck in the garage. Hitting shots with visual swing feedback is great, but getting some pretty accurate data at a very fair price point would be huge.
Definitely will be curious to see if they expand at all into incorporating club face and path metics down the line!
“. . . the SC4 Pro is a very capable and competitive unit when looking at others in the market in this price bracket.”
I agree, and would love to have one!
$600 for the whole package (unit, case, stand) is not in my budget right now, but if I start saving, and if it ever goes on sale (I know it’s $50 off right now, but would hope for $100), I will seriously consider a purchase.
This is a great write up [USER=782]@ddec[/USER] on the SC4 Pro. For those looking for a LM with a low cost entry point it would be hard to beat the features offered here! Great improvements from the SC 300 (can’t remember if that is the name or not) that I had a long time ago.
Features that stand out to me are the range, ability to play back shots and the inclusion of SIM play.

Great review Dean. SC4Pro Speed Training reads the little ball on my orange whip lightspeed too.
Hopefully I can post this deal here as there seems to be some interest? The SC4Pro is still available from Breaking Eighty website for $500 ($100 off) as is the protective case for $30 ($20 off). That deal supposedly expires on 4/13. That’s the route I took to purchase my unit several weeks ago. Mine shipped directly from Voice Caddie and arrived within a few days. I’ve been extremely happy with my purchase. If I wasn’t supposed to post an offer from elsewhere please delete this ddec.

So where have you been using yours since you purchased it? Mostly outdoors or inside?
I’ll leave the offer info up to [USER=5944]@jdtox[/USER]
I don’t have a dedicated indoor setup so almost all my use is outdoors. Indoors, I’ve only done a few sessions of orange whip speed training in my vaulted ceiling living room, and then only when my wife isn’t home?? Everything else has been outdoors, usually at a driving range (3 times already this week), sometimes at a dedicated short game area, sometimes I erect my backyard setup so hitting into a net. I’ve yet to run into a situation where my SC4Pro failed to perform up to my expectations.

Nice I love hearing that. Do you use the app when at the range or just rely on the onscreen info?

The size and quick setup are big pluses!
I’ve been keeping an eye on this since before Christmas. It seemed like there were a lot of individuals that weren’t happy because they dragged their feet a bit on releasing a (promised) Android app. If they’ve finally got all their ducks in a row, this could be a solid option for the price.
Almost always use the VoiceCaddie S app as it allows me to download and later work with whatever data I was gathering. Sometimes I’ll use the E6 Connect app instead as it includes some extra practice modes (including some exceptionally good short game stuff), and their sim courses. I haven’t really looked into how?/if? session data might be downloadable outside the app since it’s been so easy and convenient to use app.
Bag storage and setup time aren’t an issue when I take everything to the range. I was given that TaylorMade stand bag to review for THP years ago. It’s a very small 4 way top and weighs in at just 4 lbs. I must’ve been planning to test out a SIM course the day I took the pic as it appears all 13 clubs were loaded into it. Still easily held my IPad, IPad clamp (hooked to back of chair), VC S4Pro, and leveling blocks with room to spare. Timewise, I’m up and working in either app within 20-30 seconds of arrival.
How does this SC4 Pro do with spin numbers from 9i on down?
I have the SC300i and it will not give spin numbers for those clubs at all. Also, smash factor for those are hot or miss, mostly miss.
I’m guessing the spin numbers are reasonable but I honestly don’t know what I should expect to see? I hit eight stock 9 irons at my last range session (mat) and got backspin readouts on all of them. They ranged from 6842 to 8525 and averaged 7905rpm. I also hit 10 partial lob wedges in target mode (mat). Was playing to a 45 yard target and again got backspin readouts on every attempt ranging from 5644 to 7173, average was 6238rpm. I’m guessing I would’ve had more spin had I been hitting fuller lob wedges but I was only swinging it ‘rib to rib’ with no real wrist set as that’s my 45 yd LW swing. Also a few weeks ago I hit fifteen 25 yard target mode sand wedges off the shaggy turf in my early spring back yard. I was very inconsistent but got backspin readings on all of them. Average backspin was 4626rpm, individual shot spins were all over the place.
I’m assuming backspin must be calculated since there isn’t a high-speed camera, correct? Assumptive formulas based off measured ball flight physics and club/loft selected?
Wasn’t expecting more than that given the price point and underlying technology. I’ve owned 3 other low cost radar LMs in the past (SC100, SC200, Garmin R10) and this unit seems to be significantly more consistent with spin metrics than my Garmin R10.

I’ve been intrigued since this review, doing some research about this and the R10.
thank you thank you for this write up. Was trying to decide between this and the MLM Pro 2 and this definitely helps me get to a decision.
I’m hoping to pull the trigger on something this summer. I think I’m down to the MLM2Pro or this, with a slight edge going to the SC4Pro right now.
I purchased one of these back in February and have been using it at work in our sim bay. The SC4 Pro by itself works flawlessly indoors, and I’m hoping to get it outside soon. When paired with the Voice Caddie S app, the range is great, keeping track of each clubs yardages with the ability to delete poor strikes is a plus. When connected to the E6 app, it came with 5 free courses and another range that works fine. Overall I would recommend this unit
