Room planner
See each one in your sim room.
The planner draws each unit to scale with your room and your swing: where it sits, and whether your swing clears the ceiling, walls and screen. Put in your room once, then switch units in the planner to compare.

Better for SC4 PRO
- Recreational Player
Voice distance announcement and built-in screen mean you don't need a phone tethered to the unit. The driving range and the five complimentary E6 Connect courses Voice Caddie lists cover casual sim play; more courses mean an E6 subscription.
- Cost-Effective Buyer
No required subscription. Sub-$600 with launch angle and apex — $50 more than the R10 up front, and cheaper over time if the range and five included courses are enough. A full E6 Connect library ($300/yr and up) costs more than Garmin's $99.99/yr Home Tee Hero.
