Default The circles and lines around surface ships

I was wondering if ANYONE can tell me what the different circles around the surface ships are? I have an idea, but I'd like confirmation. I looked all thru the manual, and couldn't find any reference to them.

Thanks,

The outer most complete circle, (if the ship has it in its equipment inventory) is the Radar range.

The next larger complete circle is the ships Visual range. These two complete circles can be confusing. If there is only one, its the Visual range. If there are two, the Radar is farther out than the Visual.

The next partial circle, that does not cover the stern of the ship, is the Hydrophone (Passive Sonar) range.

The smallest, usually half circle, that extends beyond the bow of the ship is the Sonar (Active Sonar) range.

=========

Planes will have the first two circles also.

Radar, if so equipped.

Visual, in either a complete circle, or similar to the Hydrophone shape due to the cockpit interference of the over shoulder view.

Thanks, I was wondering about that. The confusing part is, I've seen sonar type circles on merchant ships. Very odd.

Some mods, and possibly the stock game too, has Sonar on some merchant ships. Far as I know, the Japanese couldn't find their back side with both hands! Least that's what some of the post war investigations found.

Pretty much what I just did. Circles? What circles?

I guess that's what happens when my default start-up routine is Realism Settings -> Realistic -> Map Contacts back on (I'm calling out info to someone, damnit, he'd better be plotting!)
