Has anyone used Dr.depth software?
 

I am trying to decide what card/software to use with my humminbird 798ci HD si and need advice before I make a purchase.

Which is it
 

No body has used any 3rd party software? Or have I just alienated the people who have?
If it's the later please reconsider. Any information you post could help others not just me.

Not you Ed. I've asked around also and no one I know has either heard of it, or if they have, just never tried it.
