Thermometer Placement?

I got one of those little digital doohickeys and was wondering if it matters where I put it... tank or sump?
 
It doesn't really matter where as long as its not right next to the heater.Those digital thermometers aren't the most accurate so I use two.One is behind the overflow tower and another is in the return section of the sump.
 
I had pretty bad luck with my old digital thermometer. Always have an old-fashioned alcohol-based backup on hand and check the accuracy often.
