I will recommend what I recently purchased, Icom M93D, it was a toss up between that and Standard Horizon HX890, and I chose the Icom. A few reviews said the menu system was confusing, but after a day of playing with it in my living room , I thought it was pretty intuitive, I have not had any real water experience with it yet, it was purchased as a backup and for my dingy, but if it is anything like every other Icom model, I am sure I will not be disappointed. It has all the latest bells and whistles and Icom has a rock solid reputation.
