I have the garmin blue 160, like I said it came with the boat, so it is obviously atleast 2 yrs old. I bought a garmin chartplotter before the season, so would like to stick with garmin. I guess if I could just learn how to tell what is bait size fish and what is a big fish, I would be content. Do you guys feel that the color ones display the size more accurate, or am I reading this one wrong? Like I said, just haven't seen that "arch shape" yet.
