How to choose
Three questions settle it for most buyers.
Do you want numbers without a phone?
The ESB1 has a built-in screen and works with no phone; the ESB2 is compact and pairs with the ES Range app on your phone. The Tour Plus 2.0 and Eagle Sim expect a computer or tablet, because they are producing far more data than a small display can usefully show.
Do you want club path and face angle?
Ball speed, launch angle and spin tell you how far a shot went and why; club path and face angle tell you why it curved. Those come from the camera-based units — the ESB1 and ESB2 measure ball and club speed by radar, while the Tour Plus 2.0 and Eagle Sim add club path and face angle.
Are you practising, or playing indoors?
For range practice, the ESB1 or ESB2 is the efficient answer. For indoor course play you need simulator-software support, which means the Tour Plus 2.0 (E6 Connect) or the Eagle Sim (E6 Connect and TGC 2019). A launch monitor that cannot drive simulation software will never play a round, no matter how accurate it is.

Most Golf AI Is Guessing. Ours Is Measuring.

What launch monitor metrics actually mean
Ball speed, smash factor, spin and launch angle in plain language, with the target number for each and which ones are measured rather than estimated.
