The Swing Caddie SC4 is both a complete simulator and portable launch monitor. For use both indoors and outdoors, the SC4 delivers professional grade swing and ball flight metrics. In simulator mode, the SC4 connects with the included MySwingCaddie App, providing a complete virtual display along with metrics and stats. To further enhance the simulator experience, the SC4 is fully compatible with E6 Connect / Optishot Orion and its suite of photorealistic courses (optional subscription). In outdoor use, the SC4 can be used as a standalone unit (no smart phone required) with its vivid display featuring carry distance, launch direction, swing speed, ball speed, smash factor, launch angle, apex, and spin rate. For a more advanced experience, the SC4 connects directly to a smartphone or tablet via Bluetooth allowing golfers to save their tracked data, record their swings, and produce swing overlays. The included remote control, voice output of distance, and rechargeable Lithium Ion battery ensures both the highest level of experience and convenience
