You can extend the range slightly more by using three pins. The math gets more complicated but if you have CAD capability, the CAD math engine will solve it easily. If you use three pins differing by +/- .0001, the diameter is 2.1547 x the middle pin diameter.By using two pins the check a hole you can nearly double the range.
yes, but holding 3 pins in line becomes a little more difficult. You can do it, but you need to use 2 bars, sticks whatever to keep them in line... if they triangle out on you, you lose your measurement.You can extend the range slightly more by using three pins.

It isn't three pins in line. They form a triangle. It is actually more stable than two pins as two pins have to be exactly parallel to each other to get an accurate measurement.yes, but holding 3 pins in line becomes a little more difficult.
