I have 2 raingages, one at the front gate and one up at the garden, a couple hundred yards away. I had a really good rain here about an hour ago, and when it stopped,. The one at the front gate read i.5 in. and the one at the garden read almost 2.5. Both are made by Accurite but are different models. I realize rain does'nt come down evenly but this difference seems extreme. What do you all think?
