As deep as she'll let me......:D:D:D

how do you go deeper then your gauge? Or maybe you can't with stock?

That's easy - just hit the 'D' for dive key. Which raises another question: if you're deeper than the guage, how do you know how deep you are?

the weird guy right behind you with that allsome bad breath, whispering: "Captain, we've just passed 900 feet"

ok.. then how do you stop the dive to level out the planes and maintain the depth once you've reached as far as you want to go?

press A...

I play TMO, not sure if's it's the correct key for stock, but A levels you off.

To read depth, there is a little digital number readout botton right hand corner, can't mission, just the number no dial.
