I’m sure that there was a video somewhere on how to pot the old four pair Fathom tether but I can’t seem to locate it. Could someone please help me with a link?
Perhaps this is what you are looking for?
Here is also the Fathom R1 Installation tutorial.
Many thanks guys. The one Kevin linked to is the one I need - finally getting a chance to fix the damage from our misadventure a couple of months ago.
