Hey all I was wondering if it is worth it to upgrade my current unit. I have the old C90W, and use it with Raymarine radar unit as well. I use it mostly for the fishfinder and radar, seeing as I have a separate chartplotter. I was wondering what the best upgrade would be that would include something like downview and even possibly low frequency side scan (for some offshore applications, and yes I know it doesn't really work like the $$$ cattle boat versions)? I would also like to get a 1000kw transducer to use with it. In all what suggestions for units with transducer and box do you all think? I am super green when it comes to the electronics aspect of everything. Any help is much appreciated!
