I'm not sure there is a "base" setting. As far as I can remember, without walking out to the boat to look, their all "adjustable"
For instance, the scroll speed is 1/2 speed, normal speed, 2X speed and 4X speed. The color has like 14 different settings and all of those can be tweeked. The ping is also adjustable.
My experience has been that everyone's settings are different than mine as I constantly adjust everything just to "see" what happens. :-)
Never satisfied with any setting.
One of the really great features I enjoy is the ability to change the zoom in/out feature on the sonar and the map.
I've completed the recent program update, but haven't been out on the water to see what the unit will do differently.
Fantastic Depth, or er... Fish finder.
