I'm not at all keen on network systems beyond the old Wind, Depth , SOG stuff..
The best plotter for my needs is this iPad running Memory Map Admiralty charts with Bob Bradfields Antaries charts. Also on here is a Navionics package.
Its in a Lifeproof case so is totally waterproof.( as is my iPhone with a very old, free , version of Navionics..)
I can use it on deck, down below, in my bunk or at home.
A clamp mount makes is extremely versatile...
Along with all the other stuff available as an app it is hard for me to justify anything else.
