  • dave:

    I have a question about this computer. I was looking at the manual and did not see any information about a digital compass. Does this computer have one ........thanx

    Hello Dave, this unit does not have a built-in digital compass. If you need to do underwater navigation you will need to use a stand alone compass or one build into a console or wrist mount.
