The difference that matters
The Ernest Sports ES Eagle Sim fits a shorter room: about 13.5 ft minimum depth against 17 ft. Only the Full Swing KIT is listed for outdoor use as well as indoors. The Ernest Sports ES Eagle Sim mounts on the ceiling, so left- and right-handed golfers can share it without moving it.

Highlighted rows differ. Figures come from each product's sources; room depth, distances and brightness are FOREference calculations using the same method for both.
Which should you choose?
Ernest Sports ES Eagle Sim
Choose the Ernest Sports ES Eagle Sim if your room is under about 17 ft deep or you want a clear floor or share the room with a left-handed golfer.
Before you buy either
- Check the room: room size calculator and ceiling height calculator.
- Confirm what each seller includes — accessories, software trials and bundles change often.
- Read the limitations on each full reference page.
