I may be incorrect but I think any adjustment to these settings effects the other two. Or if you increase GAIN on 2d you are also increasing BRIGHTNESS on dv/sv. Not positive about that tho. Some run the BRIGHTNESS up to wash-out stage and then backoff to what they like. Thing about it is you must alway be willing to make adjustments depending on conditions to optimize the sonar. I don't always take advantage of this however.
That is pretty much what I posted in the other thread what he asked the same question. These little units run pretty well in auto or default. I haven't done as much tweaking as I did on my Humminbird core units.
