Home Simulator Builders
You're building a garage, basement, or net practice room and want simulator capability without a $5,000+ camera system. Pick the SC4 PRO — 9 metrics, VoiceCaddie S app, E6 Connect ready.
Net Now, Sim Later
You want to start with a net today and add a screen, projector, and E6 software when you're ready. Pick the SC4 PRO with our Home Package — the cheapest way in, with a clean upgrade path.

Swing Caddie Buyer FAQ
All three use the same 24 GHz K-band Doppler radar technology. The differences are data depth and simulator capability: SC200 Plus shows 4 metrics on-device with no app needed; SC300i adds launch angle and apex on-device, plus spin rate, video overlay, and per-club averages via the MySwingCaddie app; SC4 PRO adds 9 metrics including launch direction and on-device spin rate, plus full simulator capability via the VoiceCaddie S app, E6 Connect, and OptiShot Orion.
The Swing Caddie SC100 has been discontinued by Voice Caddie. The closest direct replacement is the SC200 Plus (more metrics, voice output, larger LCD, AAA batteries, $279.99). For a step up, look at the SC300i.
Yes, for the price points. Swing Caddie monitors use 24 GHz K-band Doppler radar with barometric pressure calibration, the same family of sensor technology used in higher-end portable LMs. They're not GC3-level accurate (those are camera-based and 10x the price), but they're trusted for club-gapping, swing speed training, and home simulator use. Voice Caddie publishes carry-distance accuracy specs in the 3% range under typical conditions.
No, every Swing Caddie works fully standalone. The SC200 Plus has no app at all (everything shows on its 4″ LCD with voice carry output). The SC300i works standalone but adds spin, video overlay, and per-club averages when you pair the optional MySwingCaddie app via Bluetooth. The SC4 PRO works standalone but unlocks simulator gameplay through the optional VoiceCaddie S, E6 Connect, or OptiShot Orion software.
All three Swing Caddies work indoors and outdoors. Outdoors, place the unit 5 feet behind the ball and let real ball flight run. Indoors (net or impact screen), aim for 8–12 feet from ball to net so the radar can register sufficient ball flight. The SC4 PRO is the most simulator-friendly indoors because of its app integration; SC200 Plus and SC300i work indoors but are designed primarily for the range.
The included VoiceCaddie S app is free and unlocks shot data, swing video, and the practice driving range. E6 Connect includes 5 complimentary courses plus a driving range out of the box; expanded course libraries are an optional paid subscription. OptiShot Orion is a separate one-time software purchase. None are required to use the SC4 PRO as a launch monitor.
The free VoiceCaddie S app is available for iOS and Android. E6 Connect ready-out-of-the-box support is iOS and PC; OptiShot Orion is PC. The launch monitor itself works fully standalone with all data on its built-in display — no app required.
No. Voice Caddie does not officially support GSPro on the SC4 PRO. Supported simulator paths are VoiceCaddie S, E6 Connect, and OptiShot Orion. If GSPro support is important to you, consider a camera-based launch monitor like the Foresight GC3.
Yes — all three Swing Caddie models work into a net or impact screen. You need 8–12 feet of ball flight (ball to net) for the radar to register sufficient flight time. The SC4 PRO is the most simulator-friendly indoor option because of its app integration.
No. Swing Caddie units use Doppler radar to track the ball, so any standard golf ball works. No club markers or stickers are required (those are for camera-based monitors).
Yes. All Swing Caddie launch monitors track ball flight directly behind the ball, so they work for both right- and left-handed golfers without setup change.
Yes. Affirm financing is available at checkout on every Swing Caddie product and SC4 PRO simulator package, splitting your purchase into monthly payments — including 0% APR options for qualified buyers.
Voice Caddie provides a one-year limited manufacturer warranty against defects on all Swing Caddie launch monitors. Top Shelf Golf follows the standard 30-day return policy on new, unused, original-condition products. Contact us at 1-888-871-6110 if you have a specific concern before ordering.
