1 SEP 42, departing La Spezia, Italy. 'Oh-Dark-Hundred'. I am following a ship out of the harbor, surfaced. On the Nav Chart I see several vessels around. When I left click on each, some of them have a 'dotted' [dashed?] circle around them, some distance out, except for a smaller pie shaped sector. That must mean something...

But what...please ? Their SONAR? I thought 'ASDIC' was a Brit invention... in those years.
