I use a Fracarro satellie inclinometer against my ladder to confirm its
at the recommended 65 to 70 degrees inclination angle before I set foot
on it....

I have a digital inclinometer I bought when I was building the 3D
printer that I was considering using for the same thing. ;-)

I have a good idea what angle 'looks right' but it's nice to get a
second (unbiased) opinion. ;-)
