Better for ES Eagle Sim
- Performance Seeker
Full club delivery data from overhead, with no stickers to apply and no membership on the data. Against a Uneekor EYE XR at $5,999 plus $199/yr it is cheaper up front, and it stays cheaper each year unless you take E6 Connect's $300/yr library over the $250 one-time course pack.
- Family Setup
Overhead mount means nothing on the floor to reposition between players. Course play is the add-on to budget: E6 Connect's five-course pack is a one-time $250, while the larger library is an annual subscription.
- Showroom
Ceiling install with the sensor out of sight and no membership on the hardware; course play is an E6 Connect purchase on top. The shorter one-year warranty and the smaller name are the trade against Foresight and Uneekor at this height of the market.
