Hello Community, tis me again.

Thought I ought to put the other thread ( birds in the rigging) to bed since you sorted the problem for me
Well 'oo's a clever girl then - I am fresh out of Naval Academy and ahead is the big wide briny.
I thought I would have a quick go at the first single mission last night, and it WAS quick. I got a bit fussed when I saw these two enormous battleships coming straight at me, and let go of two torpedoes much too soon - and the terriers guarding them were on me in a trice, and GOT me.
I have looked at the tips on evasion, which are useful, but wonder if there is a way that I can know when they have 'spotted' me, so to speak, so I can start taking that evading action rather than hang around wondering if I will be noticed.
All tips gratefully received
