Don't get sucked into anything else but a Lowrance/Eagle if you want a handheld. I have an Eagle Explorer but I had used Garmin126 which the other bloke upgraded to a 128. There is no comparison between the two. The Lowrance made one eats the Garmin. The Garmin 126/128 are the dash mount units with the same basic program as is running in the Garmin 45/12/12XL handhelds.
