Howling:River's Sonic

I wonder what river's / the doctors future sonic screwdriver can do that the previous can't? The damper presumably blocks out any interfering signals but would likely use more power otherwise it would always be on. Although, some of the features make me think.

What does the red setting do? I thought it was unique to this screwdriver but I saw it change to blue as well and the doctor used it in cold war. I think, at least with this sonic, that it increases the power of it but again would probably drain more power.

I found this link about its functions.

Some of the capabilities I understand, and I like the finger hold but what about the tardis remote return? Can this sonic control the tardis' flight?! Also just wanted to start a general discussion about it. --Coop3 ☎  22:09, August 11, 2013 (UTC)
