Sorry, clarification on Senses

[acowie]

Sorry about the touch comment, that may have muddied the water.
In the example of Detect dealing with Detect Magic it states that the mage has to touch whatever he wants to Detect Magic on, so he buys Ranged to allow him to Detect at Range.
Now. as Spatial Awareness is built as a Detect Physical Objects with no Range (though it does have a 2pt Sense adder and a 10pt Targeting adder), why do you not need to touch the physical objects to Detect them?
Or does Targeting include/require Range? Maybe I've missed that (NRBH).
But I'm sure Ultrasonic Hearing also is a "Detect Ultrasonics, Sense" - no ranged mentioned.
Would a build "Detect Physical Objects (10), Sense(2), Targeting(10), Ranged (5)" have any advantage over the current build?
Thanks very much.

"No Range," as noted on 5E 197, generally means "within HTH Combat range" -- which is to say, in the same hex or adjacent hexes. Thus, someone with Spatial Awareness has to be near objects to sense them, but doesn't necessarily have to touch them.

In some cases, as with Detect Magic, the lack of range is expressed as requiring touching, because that's a special effect.

Keep in mind also that most Enhanced Senses are assigned to a Sense Group that provides them with Range automatically.
