My wife & I both got CTX's & like them fine, great detectors----except---the lower shafts are loose on both of them.---We are easy on our detectors & take good care of them but I noticed tonight my wifes coil was out of alignment with the machine & upon checking, seen the shaft was loose from the camlock not tightening enough.---I then checked my CTX & it was the same way.---There is enough looseness & wiggle on the shafts to put the coil out of alignment with the machine.-----Anybody else had this problem & if so, what's the answer to a remedy for it?----The camlocks just aren't locking tight enough on the lower shafts.--------Del
