I don't get why it is not working, I can rotate the compass body and the ball inside stays fixed on the direction. When I travel on the bottom at 270 degrees, I deviate and correct and I expect to loosely track but maintain my direction. When I surface I am facing the opposite direction. Hmmm I wonder if the sub is rotating during the assent, that would make sense. I will have to watch the compass while I am surfacing, maybe the sub develops a spin.</div><div id="yui_3_16_0_1_1438337398118_3173" dir="ltr">Hank</div></div></body></html>
