I find it very interesting that in the first few years of SI there was a frequent reoccurance of people wanting to be able to "turn off the dark water column"...
Then, after HB finally released a software update to "turn off the dark water column" the Internet chatter was like....nill...nada...nothing....
I wonder if people realized that the water column gives more information than they we're willing to give up...just to see the bottom in 1 big unbroken image...
