After I have used my AT-Pro in the water I like to take the rods apart and wipe the water and sand off them. I'm finding that it is almost impossible to separate the rods. It's almost like the water fuses the rods together. There are times when I want to change coils and I have not been able to take the lower rods apart ( all my coils have their own lower rods ) Has anyone else had this problem or don't you take yours apart ? Any suggestions would be greatly appreciated.
