Navtronic Vs Lakemaster Chip

[ds]

I am plannin on buying a H20C and was wondering if there is any difference between the Lake Master and the Navtronics chip.

Thanks

I have both. On lakes I perfer Navionics. I use the lake master when I use my GPS while traveling in the truck as it shows all roads including township roads and city streets. Navinatics will only show lakes. I would suggest getting which ever one has the lakes you fish most in detail. The lakes in both which are not in detail are simply DNR background maps.
