I told you I would kick myself.  I briefly considered that Chuck meant SPG
without thinking about the location of the keys, then dismissed that,
focusing on the depth guage.  I could not come up with anything like SPG for
depth guage . . . duh.  Funny how such a simple thing as being reminded of
where the keys on a keyboard are can make such a difference.

Sorry Chuck, got it now.
