Now as you look at the next set of screenshots notice the outlined sections, these are your basic controls, each sub is similar but not the same, there are options on the SW's helm screen that aren't on the other two subs and vise versa.


Note the circle designated 6 is the High Frequency Active sonar which in the 688I is ofcourse as you can see on the Helm Screen, this is not the same in the SW or the Akula. The HF Sonar is used for under the surface Ice navigation and if there is a mine in it's range it will display it so you know where it is!
