Good Day, Navionics Hot Maps Plantiun vs Lakemaster plus v2. The above video is showing exactly what I am trying to achieve with my Hummingbird 3gn SI_DI. I currently have a Lakemaster 2 installed and working, BUT I can not get anything other then 10' increments on the depth sonar. How can I get better readings? 

 

Does Lakemaster 2 have this capability? I am hoping so, for $150 ,10' depth increments will not work for me. 

 

Thanks, Dave
