Pinless Meters use electro-magnetic wave technology which measures density in a 3-dimensionaI field underneath the instrument. If moisture varies within the segment, the meter cannot indicate the changes. Settings are available for correction of different wood species. Not affected by wood temperature. 

  measuring depth 1/4" and 3/4".

>Gives precise readings and is 
  a good indicator for evenly or 
  unevenly dried wood.
>Leaves two pin holes.
>Indicates highest moisture in 
  area between pins. Can 
  measure differences between 
  core and surface moisture  
  by using insulated pins which 
  measure only at the  depth 
  they are driven to.
>Not affected by surface texture
  or shape, as long as both pins 
  can be inserted.

>Measuring depth up to 7" with 
  #EL pins, can be extended by 
  remote cables and probes.
