Voice Caddie's launch-monitor comparison and product pages were checked October 21, 2026. The SC300i screen-size figures conflict between the manufacturer's comparison and product pages, so no exact display size is used here.
Quick answer
Choose the SC4 PRO if you want Voice Caddie’s 3D simulator and the broader ball-flight data set. Choose the SC300i if your priority is range practice with carry, speed, launch angle and apex on a standalone unit. Voice Caddie’s comparison lists MSRPs of $599.99 and $399.99, respectively; the SC4 PRO is $200 more before any current offer.
The supplied BASSOLINO15 code is 15% off eligible purchases. On those listed MSRPs, that is an estimated $90 off the SC4 PRO or $60 off the SC300i if accepted.

| Radar and listed range | 3-Doppler; 15–370 yd | Doppler; 10–370 yd |
| Launch and ball-flight detail | Launch angle, apex, launch direction and spin; app adds spin-axis, side-spin and dispersion fields | Launch angle and apex on the unit; spin rate in the app |
| Simulator support | VoiceCaddie S 3D driving range; E6 Connect compatibility is listed | MySwingCaddie data and analysis; no E6 or other simulator-app support listed |
| Screen and readout | LCD and voice output | LCD and voice output |
| Battery | Rechargeable; about 10 hours listed | Rechargeable; up to 20 hours listed |

These are manufacturer specifications. We did not run the units side by side or independently measure their accuracy. Voice Caddie’s SC300i product and comparison pages disagree on its display size, so we leave the screen dimension out of this comparison.
Which one fits your practice?
Pick SC4 PRO for a home simulator and more shot context
The SC4 PRO is the more capable option if you will use its included VoiceCaddie S 3D driving range. Its listed launch direction and additional spin fields give you more information to interpret a miss. E6 Connect is also listed as compatible, with its own subscription requirements; check the current software and device requirements before building a setup around it.
The trade-offs are the $200 higher listed MSRP, a heavier 20.79 oz unit and a shorter listed battery life than the SC300i. It still uses radar, needs a real ball and requires clear space behind the hitting position. It is not a camera-based impact system.
Pick SC300i for simpler range sessions
The SC300i keeps the core monitor workflow straightforward: place it behind the ball, use the screen and voice output, and connect to MySwingCaddie if you want saved history or app analysis. It reports launch angle and apex, while spin appears in the app. It does not provide the SC4 PRO’s listed 3D simulator compatibility or extra launch-direction and spin-axis fields.
If you are deciding between all three Swing Caddie models, the SC200 Plus review covers the simpler speed-and-carry option. Our launch monitors under $500 guide compares the SC300i with other portable systems.

Frequently asked questions
What is the main difference between the SC4 PRO and SC300i?
The SC4 PRO adds Voice Caddie S 3D simulator play and more ball-flight fields, including launch direction and spin-axis information. The SC300i costs less and still shows launch angle and apex, with spin in its app.
Is the SC4 PRO worth $200 more than the SC300i?
It is the better fit when you will use its 3D simulator and additional launch data. If you mainly want range feedback for carry, speed, launch angle and apex, the SC300i keeps the purchase price lower.
Does the SC300i work with E6 Connect?
No. Voice Caddie lists simulator compatibility for the SC4 PRO, not the SC300i. The SC300i connects to MySwingCaddie for saved data and analysis.
How much can the Voice Caddie code save?
The supplied BASSOLINO15 code is 15% off eligible purchases. Applied as arithmetic to the listed MSRPs, that is about $90 on the $599.99 SC4 PRO or $60 on the $399.99 SC300i.
Does BASSOLINO15 stack with Voice Caddie's current offer?
On October 21, 2026, the SC4 PRO and SC300i product pages displayed an 'Add to Cart For 20% OFF' offer. Do not assume the supplied 15% code stacks or replaces that offer. Compare the final totals.
