Hey all, im half intrested in a new sounder but i dont have any idea as to what im looking for. is there any advantage to a colour screen as to B/W? im not too fussed if it has a gps or not its only going on a 12ft punt so i wont be taking it out too far. i do want to have temp and a speedo and to be around the 500 - 600max mark. even if someone can share a link that might help me to know what to look for. Cheers, Karl.
