Ijust got mine and pointed directly on my thermostat probe and the gun said 78 degrees but the thermostat reads 89 degrees and my digital thermometer reads 90 degrees...what is going on
I picked up mine yesterday, and I'm pretty happy with it. It comes with a laser pointer which makes it a little easier to use, or maybe just more fun. They're going pretty quick, though. Apparently there are some Ebayers that are cleaning the shelves to turn a profit on Ebay.

I read this about infrared thermometers. It might apply to your situation if you are pointing it towards a shiny probe:
I can not speak about how well this model performs, but for the average user it is probably sufficient. This is not a "laser" thermometer it is an infrared thermometer. The only function of the laser is to get an estimate of what surface you are measuring. It is actually measuring radiometrically the light waves just beyond the visible spectrum (typically in the 8-14nm wavelength range). There are several things you need to consider when using an infrared thermometer. First and most important is the emissivity of the surface you are measuring. This instrument most likely has an emissivity setting of .95; surfaces that are near this emmisivity include flat black paint/tape, carpet, wood, human skin. Shiny reflective surfaces like mirrors or aluminum have very low emissivity.
The other thing you need to consider is the distance to size ratio (d:s), usually this is identified on the side of the instrument and tells you how large of a spot you are measuring. For example a 10:1 ratio would meant that at 10 inches away from the target the thermometer is measuring a 1 inch spot (circle). The farther away you are from the target the larger area you are measuring, typical rule is for more accurate readings you should at least cut the d:s ratio in half.
should these already be in stock at your local lowes or do you to have them ordered first?.
They should be in stock, but it's convenient to order online. The online order will confirm whether they have it in stock, and it will also reserve it for you in case they are running low.
