If the weather is good is much better to stay tuned with the "radar detector", so you'll be noticed of the presence of a DD (or maybe a convoy) before (if you detect the signal soon enough) they detect you.
But nothing prevent you (in SH3) to use radar in a beautiful sunny day!

Hmm, so maybe I'm confused with using radar in foggy vs. clear weather.

In foggy weather (with God's eye enabled) I can see a grey outline of merchant ships. In clear weather I cannot spot/find ships with grey outlines. Is this how SH3 is supposed to work?

Sorry for asking again; this has been on my mind for a long time.

p.s. Otoh, I -always- turn radar off in clear weather, it's too dangerous then (I think). Maybe I'm just missing it in good weather because I turn it off
