For the past two years I have been unable to get the shaft anodes with the copper contact. What I can get is an egg shaped anode with a hinge system that provides a larger surface of the zinc in contact with the shaft.\There is a difference. I haul once a year, not always at the same time. In the summers, I always get to dive and inspect. The copper crush kind have never, NEVER presented for a summer inspection. Last year was the first year with the hinge kind, and some zinc was still there for my next haulout, 14 months later. I won't be going back to the copper contact kind if I can control it.
