Just bought two echomap 73 sv plus units. Only had them out once. I'm going to like them!
Sangchris and shelbyville appear to be mapped, not coffeen. I just checked on active Captain app. I'll try to remember to double check tomorrow, on the unit. I'm not sure if it's on the lakevü ultra HD card, get on garmins site and look. Use the link from empty cooler.
The plus units are touch screen, come with quickdraw contours loaded.
At first I was leaning away from touch screen. Now that I have it, I like.
