Ok, as requested, I have pics of my new dual temperature thermometer! This is a digital indoor/outdoor thermometer I bought at Wal-Mart.
As you can see in the first pic, I mounted it to the back wall in the cool end of the tank.

You can see below the pic where the sensor wire goes down into the sand. I left some exposed for the pic.
I ran it down the wall to the base, under the sand across the back wall, behind the rocks, and back up to the basking area.
In the next pic, I've uncovered the wire where it runs under the rocks that form the basking place.

I then ran it back up the wall behind the rocks and lodged it between the rocks and the backwall. You can see the sensor in the last pic. I didn't take the tape off the stick pad because I didn't want to permanently mount the sensor so that I can re-arrange if I so choose.
