Default Two types of persicopes....?

I've been reading the spec sheets on some subs and a lot of them have 2 different periscopes equipped, an "Attack" periscope and a "Search" periscope.

http://www.globalsecurity.org/milita...-688-specs.htm
http://www.globalsecurity.org/milita...-688-schem.htm
http://www.globalsecurity.org/milita...-774-schem.htm

What's the difference between the two? I can speculate, but its still a little unclear about why the two different types...

The search scope has a big lens to let in lots of light (for low light operations, not really important in the era of LLTV) and gives a wide field of view (useful for… well… searching).

The attack scope is smaller (harder to see) has a more limited field of view and has gadgets like radar range finders (now laser range finders).

Good to know...Even the VA is showing two different types of scopes for its optical mast.

Attack scopes are generally taller (greater distance to horizon) and thinner (lower cross-section/visual profile). They are also rarely used, as they do not gather as much light and the image quality is lower. That is not always the case, but it is generally true.

That's interesting. From their names I'd suspect the opposite, if there was any difference at all.

I was wondering why the range finding system in DW scopes is based on visual manipulation and not on laser technology (laser range finding is so common and faster).
is this the real situation on the subs that are moddled for DW?
