Regardless of which unit you go with, make sure to check out Jolly Ann Marine and Outdoor’s web site. I have purchased a few items there and it is always an outstanding transaction. If you live outside of Iowa you can save with no sales tax and I think some of the units have free shipping.
I am not sure about the pros and cons of color and grayscale, but I don’t know that I am missing much with my grayscale LMS-480 ( in my dash ). I do regret not having a combo GPS unit up front. Trying to key in on a rock pile or other type of submerged structure would be alot easier with a combo unit. I think the LMS480 is just under $500 without a transducer or about $40 more with one.
I am saving right now for another LMS-480. I am going to buy it this month…
