Here's the Full Rundown on the
Swing Caddie SC300i Launch Monitor Upgrades


Voice Caddie, a leader in golf technology, has launched a refresh of their SC300 portable launch monitor—the Swing Caddie SC300i.

This golf gadget company is known for their line of GPS rangefinders, laser rangefinders, and Swing Caddie golf launch monitors—and their attention to feedback from pro and amateur golfers alike.    

In keeping with their mission to provide affordable, professional grade launch monitors, Voice Caddie took player feedback and smoothed the rough edges of the SC300.

In this article, we bring you up to speed on the SC300i features, how it works, what’s been updated, and why we recommend it.

Professional Grade Features at an Affordable Price

Measures Multiple Metrics

You get instant feedback on your shot! Core data appears right on the SC300i screen, including Carry/Total Distance, Smash Factor, Launch Angle, Swing Speed, Apex (Max Height), and Ball Speed.

High-Performance Doppler Radar Technology

This latest personal golf launch monitor from Swing Caddie uses Doppler radar technology and calibrating atmospheric pressure sensors to give you uncompromised precision.

Voice Output of Distance

The Swing Caddie conveniently calls out the distance of your shot while you’re hitting, so you don’t have to constantly go over to the screen.

Real-Time App Integration

Get your shot data for each club in real time on the newly updated app—MySwingCaddie 2.0. New stats data and shot video recording with data overlay provide greater in-depth analysis. Available for Bluetooth-enabled iOS and Android devices.

Includes a Remote

The SC300i comes with a remote that, like the Voice Output, negates you having to walk over to the launch monitor every time you want to switch up clubs. Voice Caddie design allows you to focus on what matters.

Improved Battery Life

The SC300i lets you collect data on your swing with up to 20 hours of battery life. That’s a considerable improvement on the previous model’s battery life of up to 12 hours.

How the Voice Caddie SC300i Launch Monitor Works

Advanced Golf Technology for Accuracy and Improvement

The Swing Caddie SC300i portable launch monitor uses Doppler radar technology along with a barometric pressure sensor that automatically calibrates to give you seriously accurate data readings on your shots.

Parameters include Carry/Total Distance, Smash Factor, Launch Angle, Swing Speed, Apex (Max Height) and Ball Speed. Placing the unit at the recommended spacing for indoor and outdoor use, gives the most accurate feedback.

Smart, Convenient Features You Want in a Golf Analyzer

The SC300i golf launch monitor is extremely convenient on several levels. First, you get an instant on-screen readout of your shot. You don’t have to keep looking at your phone or tablet. However, if you prefer real-time data through the now updated MySwingCaddie 2.0 app, this is an option as well, via Bluetooth connection to your iOS or Android device.

Second, the Voice Output feature announces shot distance automatically after each shot, so you don’t have to walk over to the device to read it each time you hit.

This portable golf launch monitor has two modes. Practice Mode displays key ball parameters after each shot. Target Mode lets you set a target distance to test your distance control. Measuring range is 15–370 yards.  

And finally, this portable launch monitor includes a remote so that you can change mode, club, or target distance without having to walk to the monitor each time.

The Voice Caddie SC300i Golf Launch Monitor Updates

Accuracy and Style

Feedback, especially tour proven feedback, is just one of the elements Voice Caddie uses to create affordable, professional-grade golf gadgets for all types of golfers. They listened to player reaction on the SC300 and polished the rough edges, refreshing both the launch monitor unit and the Swing Caddie app. We think you’re going to love the updates.

For starters, the sensor is a completely new and improved doppler radar sensor. The new SC300i has been stringently tested in Voice Caddie’s laboratories to make it even more impressive. The sensor systems are so robust that they perform in high accuracy in all conditions of sunlight, altitude, barometric conditions, and more!  

On top of all that, the Swing Caddie SC300i has an increased battery life (nearly 2x) and a sleeker design. Because no harm in looking the part, right?

Swing Caddie App Update

Without a doubt, one of the greatest improvements associated with the SC300i refresh is the new version of the app—the MySwingCaddie 2.0. After being in a rough beta version for some time, Voice Caddie is now sporting a serious app game.

The great thing about this is, even if you already purchased the SC300, the app upgrade is free and available to use with the SC300 or the SC300i.

The upgraded app includes:

  • social login
  • new modes for a variety of practice (instant shot feedback for all data points, video recording of your swing for in-depth analysis, and simple view of what you need to improve your game
  • new Target Mode with scoring of shot data
  • new stats with multiple ways to review what you’ve done
  • data overlay on video recordings of your swing

Anyone found a way to accurately set loft/lie angles? I play Cobra One Length and some of my lofts are ‘.5’ and while the app appears to have a decimal place, it won’t let you set anything except a whole number. Additionally, my GW is 49deg loft and the GW setting is limited to a min of 50 deg. Makes no sense and I’ve emailed the company, sending them Cobra’s sheet on the loft/lie angles but unable to get a response.

@Rober Jackson— Thanks for your question.

Comparing units side by side can be difficult as a small change of unit position does cause units to read ball in flight differently. Swing Caddies do not account for wind, but the SC300i does have launch angle, which can affect ball speed. When using both units side by side, it is advised to have the SC200 plus on left side of SC300i to have radar sensors as close as possible for best readings.

Theresa - July 6, 2021

@Dillon Funk — Thank you for your question. According to Voice Caddie, Max swing speed for Swing Caddies is around 125 MPH.

If you let me know which model you have, SC200, SC300, SC300i … I will send you a setup/FAQ guide to see if some factor can be detected.

Theresa - July 6, 2021

@Lance Bendiak — After consulting Voice Caddie, it’s our understanding that elevation can cause a slight variance from exact reading, but generally will not cause major differences. It is also Voice Caddie’s experience that they’ve had no cases of these specific differences before and have “countless customers at the same elevation with no complaints.”

The difference from unit distance to actual distance can vary due to multiple other factors. In case it may help, I am emailing you a setup FAQ and guide for updating/resetting your device. Please let me know if you have any further questions!

Theresa - July 6, 2021

@Mark Robinson — Thanks for your question. The SC300i can be charged using 220 volts and no adapter is needed. Also, higher voltage will charge the unit faster.

Please reach out if you have any more questions.

I compared the SC200+ vs the SC300i and the SC300i is constantly 10 yards shorter in distance. I set the correct loft, positioned the SC300i 5 feet back, and straight behind. The swing speeds are correct but the ball speed is lower. Does the SC300i account for wind? For example SC200+ PW carry 114 smash 1.25 club 67 and Ball 84; SC300i carry 101 smash 1.07 club 75 ball 80. I had both units side by side.

What is the max swing speed it can measure? Got the swing caddie and it seems to be pretty accurate once the lofts adjusted to match my clubs. However it doesn’t pick up every shot specifically with the driver and longer clubs. It seems to not pick up swings over 116ish mph. It’s happened with multiple woods and longer irons. Tee height, launch angle didn’t make a difference only swinging slower seemed to help is there a max swing speed it can detect?
Lance Bendiak - June 24, 2021

I live in Calgary, Alberta, Canada and have a SC300 with the updated app. We are at about 3000 ft above sea level. The barometric pressure shown at startup seems to be about 13 percent lower than data from weather apps. I have checked actual distance on shots versus the SC300 distance and the SC300 seems to overestimate distances by about 13 percent. Has anyone else who lives at elevation have this issue?

Mark Robinson - June 23, 2021

Hi, I’m waiting for my unit to reach Thailand. I just want to confirm that I can charge the unit using the local current of 220 volts. I prefer not to have to use a voltage converter. Thank you.

Theresa - June 2, 2021

@Andy, thank you for your question.

Almost Golf Balls will not work with Swing Caddies due to minimum ball speeds not being met for reading to occur. It’s best to use real golf balls with this product.

Please let us know if you have any other questions.
