I had the H2O color with MN Lakemaster, it is an average unit, will get you where you need to be just fine. Going to a Garmin GPS Map76CX from Wade at Jolly Ann, with the MN Lakemaster. The main thing I was unhappy with was the small things, going through batteries like candy, slow in aquiring satellites, having troubles with the power cable, sending it in a couple times with crappy customer service..just stuff that drove me nuts. I may have the same troubles again, but I”d be kicking myself for not giving it a try. As I understand the antenna in the Garmin is much more accurate, the battery life is far superior, but it does cost a bit more. Just my two cents.
