head unit

asking $950 shipped for all of my Neptune Apex equipment. Included is 1 Neptune Apex head unit, 2 energy bar 832’s, 1 salinity probe, 1 temp probe, 1 ORP probe, 1 PH probe, all wires and cables, 1 break-out box with switches and leak detection sensors, one magnetic probe Holder, calibrations...

Hey guys! I have the Neptune Apex JR with the temp probe. Am I correct in thinking that I can buy the full apex base unit and then connect my energy bar 4 and my apex display and add a PH probe, and I will basically have a full apex system, sans the energy bar 8? Thanks for the input, MSB
