One of these days when I have some time, I am going to figure out how to get range w/o pinging as well. I just need to dedicate some time to sit down, do some searching for different techniques, and actually read them through them all the way. I would like to figure out the mast height to calculate range, and ship length for speed, as well as a good way to accurately calculate the AOB. One step at a time....I'm definitely making progress
