I am looking for a tripod to use IN the Great Salt Lake. The south end of the lake is four times more saline then the ocean and with the other concentrated minerals is many times more corrosive. The north end is even saltier due to a rail road causeway that runs across the lake. In short the lake eats metal. I am looking for a tripod that will hold up to the lake and can be dismanteled in the truck and washed out. I am doing this with several bogan aluminum legs with good luck but does anyone know of a tripod that works well in a exceptionaly harsh enviroment. It will hold up to a 4X5 and lens, about 10 Lbs.
