Question. So I go out and spring for a chart program for my Helix 9. Can I Make a copy of this chip for my Helix 7 to use simultaneously ? I understand that I can not network the two units.

No you cannot copy a Lakemaster or Navionics map card.

Now you an by a Navionics + Region card for $149 that covers from Maine to South Carolina, then you can use that Region card to activate a Navionics Update card and that covers everything in the U.S. to South Carolina.  

 

Using a Navionics+ card to activate an UPDATE card was discussed on *** and that wasn't known if it can be done and a Navionics+ card is not listed as a card for that.

Does it matter if you're in 2D or Side imaging when motoring around making the map, or will it still record the depths on either setting?

No, only the center of the 200 kHz pulse is used to measure the depth and that is active all the time you have a depth readout.
