國軍-81迫擊砲水平計算

Are you tired of rotating the board every day to calculate the position and distance between the mortar position and the target?
Are you afraid that you are too nervous during the test and lack of sleep will cause your hands to tremble and your eyes to look at the picture board?
Are you worried that the grip strength is too strong and the drawing board pointer pen is damaged and cannot pass the high-end inspection?

The digital age and digital thinking are worthy of your digital computing power
Cloud computing? No! GPS location detection? No!
Lock Bluetooth, Wifi sharing, camera? No need (I don’t need it anyway)

Even if your smartphone becomes a brick, you can complete the shooting mission!
Allows you to have the ability to achieve high-speed "illustration of the first elements", "complete shooting preparation", and "test point test shooting".

"After training E0123 ladder 1B1C020, here is for you"

***Remarks***
1. Please bring your own shot table
2. In principle, the accuracy rate is quite high, but there is a lack of board verification, please confirm by yourself before formal use
