Get early warning of "Osmosis" before visible gel coat blistering 

Simply move the sensor from spot to spot to reveal abnormal areas which may require more detailed inspection.

May be used for examining woodwork, such as shipwright carpentry without damage, to reveal the likelihood of rot.

Because the meter readily detects water well below the surface of wood or fibreglass, even qualitative readings

offer great value in locating moisture, hidden water pockets, and leaks.
