This was the first EMF meter that was built specifically for paranormal researchers. 
 This is the "Basic" Mel Meter that was introduced in 2008. This instrument includes all of the essentials features used by Professional Paranormal investigators. However, it does not include an expansion slot. The expansion slot is a cost saving feature that allows the device to be upgraded by DAS with new features at any point in time. If you think that you may out grow the basic Mel Meter, select the Mel-8704R-ProNav Model that has the expansion slot built into it.
