Anyone try the newer 3d sonars like Raymarine RealVision

Anyone try the newer 3d sonars like Raymarine RealVision?  Looking to maybe add a new toy to the boat this year, so was thinking about adding additional sonar.  

I was looking at a Axiom 9 and a thru hull ducer to run RealVision.  Not sure it is worth it though.

Which model are you looking at?They are far more popular in the saltwater market,so should do well on the Great Lakes.I have 2 Axiom 12s,seems like nobody was interested in them when Gander Outdoors went out.But good reviews on them,I have yet to find out as they are still in the box.
