3D Doppler radar at this price is hard to argue with. The ball data is accurate and the REV-D update improved the spin readings noticeably over the original. Good monitor if you want radar over camera.

Buyer's Guide
Is This Right For You?
The Range Rat On A Budget
Wants real ball-flight numbers at the driving range without paying a monthly fee. The ESB1 REV-D pairs to your phone in seconds and carries zero subscription cost, ever.
Great fit
The Indoor Practice Hitter
Hits into a net or screen in the garage and wants carry, ball speed, and spin without an overhead camera install. Doppler radar reads the shot from behind, so there's nothing to mount above your head.
Great fit
The Traveling Golfer
Wants a device light enough to throw in a golf bag or carry-on and use anywhere, indoors or out. Under a pound with a carrying case, the ESB1 REV-D is built for exactly this.
Great fit
The Full Sim Room Builder
Wants a permanent GSPro or E6 Connect setup as the centerpiece of a dedicated simulator room. The ESB1 REV-D can connect with a compatible upgrade, but it's built first as a personal monitor — an overhead unit like Uneekor or TrackMan is the better dedicated sim choice.
Worth knowing
Before You Buy
Space You'll Need
The ESB1 REV-D is a behind-the-ball radar unit, not an overhead camera, so it doesn't dictate your room layout. Set it down, take your normal swing, and it reads the shot.
4–6 ft
Placed Behind Ball
No Mount
Ground-Level Use
Indoor or Outdoor
Range, Net, or Sim
Using it indoors? Give yourself normal full-swing clearance — roughly 9 ft / 2.7 m of ceiling height and a similar swing radius — plus the 4–6 ft behind the ball for the unit itself. Most garages and home ranges already have this without any changes.

What You'll Also Need
Hitting Net or Screen
The ESB1 REV-D measures ball flight — it doesn't stop the ball. You'll want a net or impact screen for indoor practice.

Practice Hitting Mat
A dedicated turf or foam mat protects your clubs and keeps your stance consistent shot after shot.
View →
Phone or Tablet Mount
Since the ESB1 REV-D displays data through the Ernest Sports app, a simple stand keeps your device visible between swings.

Planning to build a full simulator around this monitor instead of using it as a standalone unit? You'll also need an enclosure, impact screen, and projector — plus a compatible software upgrade to run GSPro or E6 Connect. Call us at +1 (424) 600 9901 and we'll help you plan the build.
