The problem is cost really good IR guns are not cheap. It is hard sometimes to suggest a 100$ thermostat suggesting a good multiple reading averaging IR gun... Most are un-able or un-willing to spend what it takes to buy one. Even then they will never be as accurate as a good contact thermometer. I agree a IR gun is a useful tool to have a cheap one will do however. They simply do not replace a contact thermometer either. I use both and I did spend the cash on a really good contact thermometer and I own a good IR gun but I think we are in the minority. Very few have the ability or are OCD enough to need to buy good ones.
