Default RE: newbie's tach question

The non-contact tach I got is similar to this one
http://abqindustrial.com/tachometers...-cdt-2000.html

If I haven't mistaken your words, I should point to the blade from the back of the prop but I can't think of any 90 degree surface on the blade that can reflect the laser to the tach for measurement

Sorry if i sound too dumb
