Vertical distance chart
 

how does the periscope e key or the vertical distance chart work, I assumed it was used to set the mast height of the target and then cross with tick mark height. Are there any videos showing how to use this correctly?

push E, then use up/down arrow keys to set the mast height.

Hi, posted this in another thread, but this is how to use the new periscope overlay to figure out RANGE:

Looks complicated at first, but easy to use once you get the hang of it.

Awesome picture for a great explanation, Thanks
