So the cyberware scanner and MAD scanner seem to be very similar in terms of lore function, detecting weapons and metal objects. However, in 5e at least they seem to have divergent rules. I'm struggling a bit to figure out what their niches are, beyond giving me multiple chances to find the same stuff.
I'm having a similar confusion with ultrasound, motion sensors, and radar sensors. They all seem to be getting at the same general idea, but I feel there must be a reason that they're considered separate functions.
Help?
