I just upgraded boats and the new one came with a 200dx installed. I have a 525 installed on my old boat, and wondering what the real difference is and which one is the better unit? I like the larger screen size of the 525, but the 200 is a dual beam unit. I will be selling my older smaller boat, and want to leave one of the units installed on it as a selling point, but want to keep the better unit for myself.
Thanks
