Must of missed where is states what is best to use as a digital green reader. I purchased something on Amazon and was using degrees, but heard that you use percentage of slope instead. I want to make sure I'm using accurate slope measurements to learn. Please advise what to use.

Hi Graham,

We use a digital level like the one below. We always use percentages (never degrees) when checking slope value.
