    G3 ULTRA MAP CARD ?

    Iwas on a mapped lake the other day and noticed blacked out spots on it .My question is is this a shallow shading color first time to notice that?

    Not sure what it is without a screenshot. Could be places not actually mapped due to shallow water, hazards, thick stumps, etc.

    Is the Ultra card compatible with the ECHOMAP Ultra? If not, are there ways to improve on the base map on the units?
