Voice Caddie SC4 PRO Review
The SC4 PRO is Voice Caddie's top launch monitor: spin, launch angle and launch direction in a portable radar, plus a 3D range simulator at no extra fee. With code BASSOLINO15 it drops from $599.99 to about $509.99.
What we like
- Measures spin rate, launch angle and launch direction as well as carry, speed and smash factor
- Includes the VoiceCaddie S 3D driving range simulator at no additional fee
- Works as a standalone unit with a built-in remote and voice output, no phone required
- Rechargeable 7,500 mAh battery, rated about 10 hours per charge
- Code BASSOLINO15 takes about $90 off the $599.99 list price
What to weigh
- Doppler radar needs a real ball and a position about 5 ft behind the ball, so it is not a camera-based indoor bay unit
- The listing gives no accuracy tolerance for this model
- Simulator play with E6 Connect or Optishot Orion uses an optional subscription
- Larger and heavier than the SC300i at 20.79 oz

Quick answer
The Voice Caddie Swing Caddie SC4 PRO is the monitor to buy if you want real ball-flight data and a home simulator without a four-figure price. It adds spin rate, launch angle, apex and launch direction to the speed and carry numbers that cheaper radars give you, and the VoiceCaddie S app turns it into a 3D driving range. It lists at $599.99. Use BASSOLINO15 for 15% off eligible purchases, about $90 off, or roughly $509.99.
Our verdict: this is the best fit in Voice Caddie’s range for a golfer who practices at home and on the range and wants to see why a shot flew the way it did. If you only chase speed and carry, the SC200 Plus does that for less.
What the data set gets you
The SC4 PRO is a 24 GHz Doppler radar. The listing names eight metrics: carry and total distance, swing speed, ball speed, smash factor, apex, launch angle, launch direction and spin rate. Launch direction and spin are what separate it from the entry radars. They tell you whether a miss started offline or curved, and whether a wedge is spinning enough to hold a green.
The listed measuring range is 15 to 370 yards of carry. The unit sits about 5 ft behind the ball on the same level as the ball. Voice Caddie says it runs without an app or special marked balls, which keeps range sessions simple.
Simulator and training modes
The VoiceCaddie S app includes a 3D driving range simulator at no additional fee. Voice Caddie also lists compatibility with E6 Connect and Optishot Orion courses, which carry an optional subscription. A swing speed mode lets you train speed without hitting a ball, a handy option in a garage with limited space.
The unit pairs over Bluetooth for saved data, swing recording and overlays. It also has a built-in remote that attaches magnetically to the back, plus voice output that reads each distance aloud. Voice Caddie currently includes an alignment stand with the SC4 PRO; check the product page for the current package.
Specs that matter
- Size: 4.88 x 7.59 x 1.14 in, weight 20.79 oz
- Battery: 7,500 mAh lithium-ion, about 10 hours, about 6 hours to charge from empty
- Operating temperature: 32 to 122 F
- Range: 15 to 370 yards carry
- Backed by a one-year limited warranty and a 30-day return window when bought direct
Who should skip it
Skip the SC4 PRO if you want camera-grade impact data, or if your only goal is club speed and carry for a lower price. A radar also needs room behind the ball and a real ball, so confirm net depth and ceiling height for indoor hitting. For a lower-cost step up in data, compare the SC300i, and see our launch monitors under $500 guide for the wider field.

Do I need a phone or special golf balls?
No. The SC4 PRO runs standalone with its screen, remote and voice output, and Voice Caddie says it does not need an app or special marked balls. Bluetooth to a phone or tablet adds saved data, swing video and simulator play.
