Smart Distance Pro 2.1.7 Full APK. Smart Remote Pro is the extended set of Smart Tools package (distance, golf rangefinder, speed). This range finder (telemeter) measures the distance to a target on a camera perspective. The effective distance is 10m-1km. To measure the distance, you should know the height (width) of a target. Do not worry! The man's height is 1.7m (5.6ft) a golf flag is 7ft, a bus is 3.2m (10.5ft), a door is 2.1m (7ft). With this, we can guess the height (width) of almost everything. If you know the airplane model, you can measure the distance from the sky. For reference, the width is 747 to 72 m.
