I'm sure everybody has different prefrences I guess a lot has to do with how much you want to spend. The color units are all the craze now but they are expensive. I use an Eagle 480 on the front of my boat transducer mounted on the trolling motor. For the money, they do a wonderful job with showing you what your over. The 480 sells for around $180.00(on sale) and you can get a smaller version with lex pixels for under $150.00.
