Wife got me an Lowarance Pro pak for Christmas. It includes an LMS 480M, in Ifinder Pro, all the mounting stuff and software and a chip that is interchangeable in both units. Bass Pro has limited amounts of these for 499$. I just looked in the BPS catalog for 2006 and the LMS480 alone is 499$ and that's discounted. I've used it one time and am very pleased. It is also a GPS unit, haven't figured all that out yet, but seems to be a good deal. Anyone else run this unit.
