The one I use for general baking is more like
this one.For cakes that require a very long baking time - extra large and dense fruitcakes, I use one of the "remote" probe thermometers that signals when the temp I set has been reached.
The cable is thin enough that the oven door will close tightly with it in the opening - I use it for roasts, chicken, turkey and etc.
They usually have an upper temp range high enough that they can be used in a barbecue and I bought my first one for just that purpose.
In fact, I found this one, which is also wireless - for folks who bake often and have lots of other things going on in the house at the same time, I think this would be ideal.
Remote barbecue thermometer - wireless! Although it has pre set temps for meats, you can program your own temps for other things.
