I bought my boat last spring and the Capac read .8 at the sea trial (in a pretty poluted harbor, lots of farm run off), .75 one week later when I drove her home, and at my dock, read .68 (in much cleaner water then I brought it froms location) and when I yanked it bottom shows no signs of pitting. I have refurbished (ground down) the sacrificial anodes tho, just because they looked skunky. FYI JAM
