Yet another 'periscope' thread...

TG626 · 01-30-14, 01:03 AM

I've read quite a bit here about attack scope vs observation scope.

The general trend seems to be that they do nearly the same thing in game, and as a result many never use the observation scope.

Now the following was in a Porpoise class sub, so maybe it doesn't apply to other classes (?)

However, I noticed today that there is one BIG difference: HEIGHT.

The Attack scope is considerably taller then the Observation scope.

Today, I was sitting in the harbor south of Tokyo. I ordered periscope depth. When I raised the observation scope it was thisclose to the surface. So close it was being washed over and I couldn't see.

I shallowed my depth 5 feet and got a clear sight and the destroyers didn't see me. Now if I had raised the attack scope at that same periscope depth it would have been towering out of the water...

I haven't checked if periscope depth is always the same, but I wonder if this is part of the "Destroyers always see me instantly" that I have read about in some threads?

( for the record I sank a destroyer and a "large European liner" before making a clean get away. )

Unrelated. In real life the observation scope was often called the "night scope" because it had better light gathering capabilities. The attack scope was about 3 inches in diameter at the top, the observation scope about 6 inches, so twice the size and could be seen by the enemy more easily in the daytime.

In the game the enemy destroyers don't see the periscopes or hear you on sonar, they put a quick call into the Psychic Friends Hotline and find you with mental telepathy.

Nuts... And here I was hoping I made some keen observation...

Funny thing about detection in game, the AI sees the nodes of your boat, not the actual 3d model if I remember right. I was testing out a snorkel that could be raised from 1000 ft and damned if i didn't get picked up by a destroyer.

Well, it WAS the OBSERVATION scope!

Snipe I do not think it is unrelated. I actually see better at night with the observation scope than I can with the attack scope.
