Oh, sorry mate. I'm refering to stock. Here's some stock screenies that answer some of your questions, but I've no idea how values will relate to your mods.
Sonar catacts:
Actual position; pretty close;
Clicking on cotact (stock):
The outer circle is the usual visual range of this vessel while the 'pacman shape' (inner circle) is the sonar range. On close up it also shows the 'dead spot in front of their Asdic. The circles appear to be averages and the 'actuals' vary greatly with conditions.
Edit: Sorry, first time I've tried a post like this; next time I'll use a bigger type face!
