Don’t worry!! Man’s height is 1.7m(5.6ft), a golf flag is 7ft, a bus is 3.2m(10.5ft), a door is 2.0m(6.5ft). We can guess the height of everything.
If you know the airplane model, you can measure the distance from the sky. Boeing 747′s width is 72meters.
Usage is simple. Input the height of the target, and touch the screen. If the target is aligned by 2 lines, get the measured distance.
* Now, 3 tools for distance were completed.
1) Smart Ruler (Short, by touch) : 1-50cm
2) Smart Measure (Medium, trigonometry) : 1-50m
3) Smart Distance (Long, perspective) : 10m-1km
Speed Gun’s Usage is also easy. To measure the speed, input the closest distance to the target, and the touch the screen following target.
If inaccurate, you can calibrate it by yourself. Thank you.
* Smart Tools does NOT include this app.
