I have a lowrance x70 (about 11 years old) and it is time to replace it. Iam looking to spend up to $600, but if I can spend less, that's even better. I do trolling on big lakes, and fish local lakes. I like color, but that is not a "must have".<br /><br />I have looked at lowrance and Eagle (are they the same company?)<br /><br /><br />Any recommendations? What would you buy if you had to buy a new one? and why?<br /><br /><br />Thanks,<br /><br />Ronald
