If you have navionics compatible electronics I would recommend going with navionics. Reason for this is the new sonar chart live that came out from navionics. The last couple seasons I have been using insight genesis making my own maps but last fall I converted over to navionics because of the sonar chart live thru the navionics app but now this year you will be able to do it without having to use the phone app. The ability to create custom maps with 1ft contours and bottom composition has proven to be an invaluable tool. You will also see a big improvement this year for lake Sakakawea maping. Navionics is putting together a good sized team to go out and log sonar.
Rusty,
$50 Navionics app? It's $14.99 for the US and Canada, $9.99 if you want just the US. Then it's a $5/year subscription for the Navionics+ features that allow SonarChart Live, Depth Shading, Water Level Adjustment, and the ability to save waypoints and trails. So if my math is correct you can use the app(US & Canada) for 7 years with a subscription each year before you reach $50. $7 a year... Not a bad deal.
