Very nice work JC, thanks for this.
It's really helped me out.
I was really struggling with getting this to work. At first I assumed it just didn't work properly in TMO 2.0.
No matter what I did, I couldn't seem to get the range triangle to show up.
Now I realise I was missing out a
vitally important step.
You
have to switch the radar into expanded mode to take your range reading.

The mod works just fine in TMO 2.0. Classic case of operator error.
Tried it out today, tracking an incoming target in light fog.
By the time he was within view I had his course pretty much nailed, and was submerged about 1500 yards off his track, just waiting.
Incredibly satisfying.
