Sam, what is your idea of "Proper water". Most would say slightly stained and a little warmer. So you can still see your cavitation plate. Oh, and with tons of marks. lol

On another note, fishing last Saturday and Sunday I noticed that the water temps were around 39 to 40 degrees. It seemed that it was quite warm for there being ice on it just a week earlier. I found some water that was 43 degrees, which also had tons of marks.
