I have one, but seldom use it anymore. The color selection was based on
scientific research at University of Oklahoma by Dr. Loren Hill. He studied
the ability of fish to see colors under certain water colors and light
penetration. I found it to be very effective in picking colors, but also
found that a handful of colors would work in my area. Haven't used it in a
while...

It did help with color selection quite a bit, and helped convince me to try
red, which I still love, as well as green, blue, purple and brown.

Mine also had a PH indicator, which I still consider useless, as well as a
temp sensor, which I used all the time.

You can still buy them brand new online...
