Yep...after just a little while hunting water...the camlocks seize up to the point you need a pair of Channelloks to unscrew them...I removed both sets of camlocks....the rod was so frozen in, it took a lot of spraying and soaking just to get the detent buttons to twist off to the side...and then had to pound out the lower rod, then I filed it so those high ridges are gone, then I waxed it with a car wax, and also inside the tube needs to be cleaned up with some sandpaper wrapped around a dowel and run through there...
it was a tough nearly impossible thing to get it taken apart, had to find a wrench to use in this fashion, (see pic) so I could pound out the rod with a dowel and that rubber mallet...its easier to change the batteries without the upper camlock, and easier to change or adjust the lower shaft too...get rid of the camlocks, and smooth everything up...also, I run the coil cable straight up the shaft, so theres a little slack up by the control box...even after doing all of this, a guy has to periodically take it apart and clean it out real good....run a cleaning rod through the tube, and wipe off the grit on the lower....
