Key Tradeoffs
Accuracy can be tuned via the GRP (group) calibration setting: hit a 5-iron five times so the unit averages your ball speed and refines its distance algorithm. Units selectable imperial (YRD/mph) or metric (MTR/kph). Key limitation: thin/topped shots that fly under the radar field will not…
Sensor Technology
0 cam · 1 (single Doppler radar) radar
Technology
Single-unit Doppler radar. The unit projects a radar field; as the ball passes through it after impact, the Doppler pulses are read and converted into ball speed (MPH/KPH), from which carry/total distance is calculated using the manually selected club's loft profile. It is a…
Ball Data
1 measured value (ball speed, mph/kph) plus calculated carry/total distance; app logs ball speed + distance + club per shot, up to 2,000 shots. No spin, launch angle, clubhead speed, or smash factor (those require the ES14 or higher models). · not provided — the ES12 does not…
Club Data
none measured. The user must manually select the correct club on the device before each shot so the unit can calculate the proper distance from ball speed; clubhead speed is NOT measured (that is an…
Sim Ready
None. The ES12 has no golf-simulator software integration — it is a standalone practice/range launch monitor that pairs via Bluetooth only with the free Ernest Sports ES12 mobile app (iOS/Android) for shot logging, Course Caddy club…

Subscription
None — free ES12 app, no subscription. Logs up to 2,000 shots.
Special Balls
none — standard golf balls; no marked balls, spin stickers, or proprietary balls required. (As a radar ball-speed gun, it detects the ball passing through the radar field after impact; no markings needed.) · Not applicable / not supported.
Mounting
Portable, floor-standing on an integrated fold-out kickstand; placed beside-and-forward of the ball. No tripod or overhead mount. · Place the unit ON THE FLOOR (kickstand fully extended from the back), 12-14" to the side of the ball AND 12-14" downrange/in front of the ball position — i.e., roughly
