Just for further clarification, I should have said "the depth on your gauge IS the relative depth you are AT," because if a "residual pressure" DOES exist, your gauge would STILL measure it. What I mean by this is if some "residual pressure" added say 3 PSI to the water column, your gauge would read approximately 7 FT deeper than your ACTUAL depth below sea level.Drewski:So, regardless of what else is going on, the depth on your gauge IS the depth you are AT.
Peace...
