I haven't gone too far on the Nautilus, but am stuck near the Wheel in the lounge. There are two items to the left of the wheel where you click on the center of each one and the arrow points to zero, 60, 120, etc. I can't seem to get the third numbers, especially after I was sure I knew what the numbers were for both of them, but nothing is happening so my figures were wrong. One walkthrough I found said it wouldn't help me, and if I couldn't get it - well, it was like - tough bounce. Could I get some help please? Thanks.

Butterfly, if you know the correct numbers, you don't have to keep running back upstairs to check them. Here is what they are and how to use them: SPOILER

Click the left dial until it is set at 120. Set the right dial to 0. Press the dome-shaped button sitting on top of the console. You will see the ship steer clear of the edge of the canyon. Now enter the next set of headings: 60, 180. Press the button again. Another close miss. Enter the last set of headings: 0, 240. Press the button. We are now clear of the canyon. You will see your mini-sub fall away from the ship.
