Which should you choose?
ProTee VX
Choose the ProTee VX if you prefer its maker, seller or ecosystem — the published figures do not favour it.
Ernest Sports ES Eagle Sim
Choose the Ernest Sports ES Eagle Sim if your room is under about 16 ft deep or you want club delivery data (path, face, loft).
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.
