Hello all,
first thanks for your tips - Steve UK i AM pointing my tail to the sonar.
Kamikaze style may work, full ahead and now and then shooting a torpedo, until crash diving below a bigger warship ..

Sailor Steve, thanks - hmm according to my books even the sub hunters of the 1960ies would never detect a Sub at periscope depth. The area above the 16 degres main beam that is shown in the diagram is indeed a dead zone - i really doubt this is correct - would only work if the emitted waves would be reflected by a thermal or density layer of any kind, and thus reflect upwards again, to make the sub indirectly visible in the sonar.

Or so i think

Any mods you would propose ?

Thanks and greetings,
Catfish
