What are the pros and cons of pinless and pin moisture meters?
With pinless meters, you can check the same board twice in the same area and get totally different readings. From a quality control standpoint, accuracy is questionable. Surface M/C, shell M/C, and core M/C--you can't check these with the pinless meter.
In a test I made with both, there was no clear preference. Note however that neither can read accurately above 25% MC.

I use the Delmhorst R2000 with the slide hammer sampling instrument with one and one half inch insulated pins. The slide hammer attachment can be used with the J2000 as well, if penetration is required. The slide hammer unit I like is the 26-ES.
All of my wood is air dried. This unit has been a valuable tool in determining the status of wood that has been drying.
