Portable Launch Monitor + Simulator
Swing Caddie SC4 PRO Launch Monitor and Golf Simulator
The Swing Caddie SC4 PRO gives golfers a portable Doppler radar launch monitor with a built-in display, voice feedback, and entry-level simulator capability in one compact unit. Use it at the range without a phone, or connect it to the free VoiceCaddie S app for deeper shot analysis, swing video, and practice sessions.
At $499, the SC4 PRO is built for players who want more than a basic distance monitor but do not need a multi-thousand-dollar camera system. It measures carry distance, total distance, swing speed, ball speed, smash factor, apex, launch angle, launch direction, and spin rate — enough data to dial in yardages, compare clubs, and build a realistic home practice setup.

Why Golfers Choose SC4 PRO
Portable Practice Data Without a Complicated Setup
9 Key Data Points
Track the numbers most golfers actually use: carry, total distance, swing speed, ball speed, smash factor, apex, launch angle, launch direction, and spin rate.
Standalone Display
Practice outdoors with the built-in display and voice output. You can get immediate shot feedback without needing to keep your phone open after every swing.
Simulator Ready
Connect to the free VoiceCaddie S app for virtual range visuals, shot data, and simulator-style practice. SC4 PRO also supports E6 Connect (iOS and PC) for expanded play options; E6 Connect adds photorealistic courses and simulator gameplay beyond the VoiceCaddie S practice range.
10-Hour Battery
The rechargeable 7,500 mAh lithium-ion battery is rated for approximately 10 hours depending on conditions, enough for range sessions and portable simulator use.
Swing Video in the App
The VoiceCaddie S app can record swings, sync shot data to video, and create overlays so you can connect ball flight numbers with what your swing is doing.
Fast Range Workflow
Set the unit 5 feet behind the ball, select your club, and hit. The magnetic remote and voice feedback keep practice moving.
Ball Data + Club Data
What the SC4 PRO Measures and Why It Matters
The SC4 PRO uses Doppler radar to track the ball in flight and report the numbers golfers need for club gapping, launch optimization, and simulator practice. It is not a tour-level club-tracking system, but it gives a strong portable data set for practice and home use.
Ball Flight Data
Carry distance, total distance, launch angle, launch direction, apex, ball speed, and spin rate help you understand how the ball is actually flying. Use these numbers to dial in club distances, compare ball flights, and see whether launch and spin are helping or costing you distance.
Club Delivery Feedback
Swing speed shows how fast the club is moving, while smash factor (ball speed divided by club speed) helps show how efficiently you transferred energy to the ball. Together, they make speed training and strike-quality work more measurable.
Setup Planning
SC4 PRO Placement for Range and Indoor Simulator Use
The SC4 PRO is designed to sit 5 feet behind the ball on the same level as the hitting surface. For indoor net or screen setups, Voice Caddie recommends roughly 10 feet from the ball to the net or impact screen. That makes it easier to fit than many radar units that need a longer indoor ball flight window.
Behind Ball 5 ft
Ball to Screen 10 ft recommended
Measuring Range 15-370 yards carry

Setup Guide
How to Get the Best Results from SC4 PRO
Level the Unit
Place the SC4 PRO on the same level as the hitting surface so the radar reads the ball flight from the correct angle.
Align Behind the Ball
Set the unit 5 feet behind the ball and align the ball with the red mark on top of the unit.
Give Indoor Shots Space
For screen or net use, plan for roughly 10 feet of ball flight from impact to screen when possible.
Keep It Charged
A full charge takes about 6 hours from drained and gives approximately 10 hours of use depending on conditions.
Use Standard Golf Balls
Voice Caddie notes the SC4 PRO is not designed to assess non-standard golf balls, so use regular golf balls for best data quality.
Pair the App for More
Use the VoiceCaddie S app when you want shot graphs, history, swing video overlays, and virtual range sessions.
Room and Enclosure Fit
Which Enclosure Fits the Swing Caddie SC4 PRO?
Swing Caddie places the SC4 PRO 5 ft behind the ball and asks for 10 ft from the ball to the net.
Net
No wall or enclosure mounting is needed: the SC4 PRO goes on its own fold-out stand 5 ft behind the ball and the net catches the shot. Swing Caddie asks for 10 ft from the ball to the net; check the specific net you pick for its own frame depth.
Floating Screen
Every width of the Net Return Floating Screen Simulator Bay stands 8 ft 6 in tall and 3 ft 6 in deep and can sit 6 in from a wall. The SC4 PRO goes on its own fold-out stand 5 ft behind the ball.
DIY Enclosure
The Carl's DIY kit needs 18 ft 9 in of room depth with the SC4 PRO behind the ball, up from 16 ft 9 in on its own.
Pro Enclosure
The Pro enclosure needs at least 16 ft 0 in of room depth on its own, and 18 ft with the SC4 PRO behind the ball.
Curved Screen
Same 18 ft as the Pro Enclosure, both up from 16 ft 0 in on their own with the SC4 PRO behind the ball.
Built-In Screen
Carl's plans a Built-In room as 12 in behind the screen for buffer space plus 6 in to install the flaps, at least 10 ft from the screen and 7 ft of swing room in every direction. The SC4 PRO sits on its own fold-out stand 5 ft behind the ball.
Our pick: the Pro Enclosure, at 18 ft of room depth with the SC4 PRO behind the ball.

Customer Reviews
Overall rating: 4.7 / 5 from 198 reviews.
The device is awesome very easy to set up. The price was the best in the market. Ordered on Friday and received on Tuesday. I really appreciate the free golf lessons from Paul Wilson body golf Thanks
The device works very well. And I look forward to utilizing all the features
It’s pretty amazing…and accurate. Gives me all the info I need and nothing that I don’t!
Fast delivery and brand new in the box. I have used it multiple times since the purchase and it works great. I could not be happier with my launch monitor choice or the store I used. Great overall experience.
Affordable and easy to use. So far so good.
Very helpful with practice and tracking numbers.
Fast delivery and new in box with that new car smell. I was not sure if this was a legit website with the deals they have, but im glad I took the leap. Started using my SC4 the day it arrived for hitting on the range. Can’t wait to hit it on the simulator. Thank you for saving me $100 that I can spend elsewhere.
Have not been able to use yet because of the weather.
Performs better than I expected and so easy to set up
This is an excellent little launch monitor, especially for the price. The device does exactly what the golfer needs it to do. I'm confident of the construction of the monitor; it's not cheap, flimsy construction that will break when tossed into a box in the back of the truck. We verified the information this generated at a range session by using a rangefinder for both distance and speed, and the device is very accurate - especially for the price. I recommend this launch monitor.
Nice monitor and easy to use right out of the box. The numbers appear to be accurate thus far.
This swing caddy launch monitor is just the golf item I needed to help improve my golf game. The data that unit provides helps me to understand some simple changes I need to make in my golf swing to obtain the maximum clubhead speed I need for better golf performance.
This was a gift for my Grandson. He requested it and seems to love it!!!
Great launch monitor to dial in your distances, would recommend to any golfer! Keep in mind that the SC100 tracks swing speed and not ball speed.
My husband is so excited
It is perfect for getting your true carry distance. No more guessing. It is perfect for storing it in the golf bag for the driving range. Very compact and easy to use!
Not very accurate
Love the SC100 swing caddie. Works flawless
I really enjoy the portability of this unit. Great price! Good swing data. The App could use an update for usage on android phone. Works great on the tablet.
Really helps understand my club distance and impact.
Works as expected - which is nice! Accuracy is close so it is a good piece of equipment, for a reasonable price, for the golfer who wants to get more / better info on distances for each club. Also helps promote discipline - and thus better training - in range sessions.
I was always wondering about the benefits of these devices. Price against usage and worth the money. I have a good friend that owns a driving range and is an ex-Pro golfer. He advised me that the Swing Caddie S200, one he owns, is great. I should get 1 he advised. So, I did, I bought the S200+ because of the remote that comes with it. Makes things and adjustments much easier. I am recovering from a knee replacement surgery. The reason for the limp in my video. But I had to try it out and I absolutely love my Swing Caddie. No matter your skill level, I recommend it to help you out and take away any guess work you may have.
This works great
Great way to improve.
Fast Shipping Excellent Communication!!!
This is my 2nd launch monitor from voice caddie. The first one was the SC 300i and that was great. Now I have the SC4 pro and all I can say is wow. Many steps above the 300i. I have used it every day since I bought it (Sept 30th) Thank you for making such a great product. I have more data to me improve my game. thank you so much. Keep the great products coming..
Since using the product, I went from hitting nine greens and regulation to averaging 14 a round. I was really able to dial in my distances, especially with my irons.
Excellent, concise instructions
The SC100 is a great value for the $150 I paid for it. At first, I questioned the accuracy, not only of the swing speed but of the carry distance as well. Once, I put the information I obtained from the SC100 to use on the golf course, however, I became a believer. At 73 years old, I am indeed swinging much slower and the SC100 has helped me choose the RIGHT club for each shot, rather than the "wishful thinking" clubs I was using.
Cheap price and fast delivery
The Smash factor is the best feature. Added at least 10. Yards to my drives! Info is the best!
I really like using the Swing Caddie Protable Launch monitor. The instant feed back helps me understand the results of each swing I make. Great tool for nerds like me.
This is soooo fun! Very helpful for me to help dial in my distances. I can't wait to get out on the course and see the strokes being shaved off!
Great product came early and very high quality. No complaints
I just bought new clubs, and it's great for trying to dial them in for my distances
Just what I needed
We wanted something portable, but high quality. The swingcaddie package was perfect. The Net Return system was easy to setup and it's durable. The golf mat has good padding and should last a long time. The mat doesn't rubb off onto the clubs like other mats I've used. The E6 connect software is easy to use and has excellent graphics. I like the fact the projector and Net Return screen can be used as an outdoor TV as well. Excellent product!
Occasionally misses a shot.
It really helps with your swing
