Ernest Sports ESB1: Room Size, Specs & 5-Year Cost

Room size: will the Ernest Sports ESB1 fit?

The Ernest Sports ESB1 sits on the floor behind the ball, looking down the target line. A radar unit behind the ball has to see the ball fly before it hits the screen, so depth is the critical dimension.

Dimension	What to plan for	How it's worked out
Depth, screen to back wall	15 ft minimum · 17 ft comfortable	1 ft screen gap + 8 ft of ball flight + 5 ft unit distance + 1 ft behind the unit
Width, right-handed only	10 ft minimum · 12 ft comfortable	Swing arc on both sides of the golfer
Width, left- and right-handed	12 ft minimum	Centered hitting area so either stance fits

Ceiling height for a full driver swing

Golfer height	Estimated ceiling needed	Working
5′6″	8′ 10″	66 in + 45.5 in × sin 45° + 1.5 in mat + 6 in margin
5′10″	9′ 2″	70 in + 45.5 in × sin 45° + 1.5 in mat + 6 in margin
6′2″	9′ 6″	74 in + 45.5 in × sin 45° + 1.5 in mat + 6 in margin
6′5″	9′ 9″	77 in + 45.5 in × sin 45° + 1.5 in mat + 6 in margin

FOREference calculationEstimated ceiling = golfer height + driver length × sin 45° + mat height + a safety margin. Steep, upright swings need more; test with a practice swing before you buy. Run your own numbers.

What it measures, and how

Building a simulator around it

Behind-the-ball radar is indifferent to handedness: left- and right-handed golfers hit from the same spot.

What else a full simulator needs

An impact screen and enclosure (or a net for practice without course play) — see enclosures & screens
A short-throw projector matched to your screen shape — see the throw calculator
A hitting mat — see mats & turf
