I was able to test my new sonar at the end of the week, helix 12 mis + g3n with the update 1.940, superb images and even with the default settings. Only problem, it draws power at 2 sonar (helix 12 msi g3n + helix 7 di g2), I ran out of power to restart the big engine after the day of fishing, I will have to make sure that my engine d I charge my battery when trolling.On the last picture we can see the head of a tree that is submerged or we used to go fishing for walleye, but since 2 years, the corner is no longer productive
