The most important feature of the resistance type meters with insulated pins is that it measures only at the depth which the pins have been driven and in a line between the non-insulated portion of the pins. User can drive pins into the wood as little as 1/8" increments to read the moisture content, distribution and range.

PIN TYPE METERS VS. SURFACE TYPE METERS.
