Re: Color vs black and white GPS/FF
 

I'm softening up the boss for this purchase. *It will be either the 332 or 337. *what I have found out though is that the chart that comes with the unit does not cover the Canadian waters of Lake Erie. *I now have to do some research to see if these are availble for the Lowrance models *Thanks for your in put. *Bill Mc ;D
I just returned from West marine the 337 model is awsome. *Do I really need 4000W of power and dual freq transducer for fishing Lake Erie?
