Mike,

I have an Altronics Performaire hand held unit. It has been real good and reliable. Mine is an older one but still works good. The info out is only as good as the info you load in. I have a 25 run data base programed into mine ove a wide range of weather conditions and I never add to it. I use it for comparison only. I track + and - compared to the predicted ET and base my dial on that. You also have to factor in the wind. Very useful tool!
