2 thermometers reading different temps???

I bought a floating type thermometer from Walmart and when I put it in the tank, the temp reads 2 degrees higher than my current floating type thermometer. They are almost identical and reads Aquarium Thermometer on the back. Anyone know why the difference? I have them side by side...

Take out both and leave it in room next to each other. Check the temp after 30min-1hour.

Probabily its due to poor quality control there is ~1-2 C dif.

Hmm, just remembered that my brother has a temp gun... I'll shoot the water and see which thermometer is accurate.

Ok, tested it and the temp gun read 82.4-82.8. I guess my new Walmart thermometer is more accurate!

Any metal dip in the tank for long time is no good, even stainless steel.

I have about 5 different kinds of thermometers and every one gives me a different temperature. My favorite so far is the digital little time and temp device. It has a probe that goes in the aquarium, a backlight and it also shows the room temperature. They're like 20 bucks on most sites.
