BP always hangs out in the open

My hubby picked up a temp gun at Home Depot - Ryobi, I think? Well, reading the instructions it says it can have a variance of +/- 5 degrees Celsius...not sure what that translates to in Fahrenheit, but that doesn't seem to be a very reliable tool with that much variance. Do we need a different brand?

I have the same one. That variance is worst case. Under the conditions you are going to use it, you can assume it to be accurate. Any temp gun in this price range will have the same variance. To narrow it down you'd need to spend serious money and get a pro-grade piece of equipment.

In other words, don't worry.
