I got on the water yesterday for the first calm day test. I was having trouble with a dark screen, trying different settings and color palettes, etc. Toward the end, I turned the switchfire to clear mode, and that helped a lot. Unfortunately, I had run out of time. I hope to get back out today or Monday and try it some more. Looks very promising so far, and the standard down sonar screen seems to be easier to read since the update.
