Hi all - I have two ctx machines and have used them since they came out for water hunting! The oring in the battery compartment is a great idea. Prior to this mod, both of my machines have been to minelab for repair!
Do however be very careful with an oring on the USB port. You may be better to use silicon etc on the existing rubber insert, or, if you do go the oring route, don't forget the loctite! An oring by itself on the usb can cause more problems - you will see small numbers on the usb screw nut - meaning the usb oring will not be totally flat and mated to the surface.
