@Hyper I agree not having it would make more of a challenge, but imagine trying to find a O2 can thats for some reason been left outside (or forgotten where dropped) a long distance away, tucked behind a hill... might take hours to find.. how about a 'half way' locator.
Instead of a display showing items point and coords, maybe the locator display could show its general direction (with an arrow for example) .. example, the O2 can is lost, we open up PC locator display, scan for O2 can, wirless signal sent out and recived and sent back to locator, an arrow showing general direction is displayed relative from HAB. Players use that bearing to track down using sight. If item if close (say 50m Radius) a X is displayed showing item is somewhere within HAB area..
