Still a very useful tool.
No doubt. In the hands of an impatient novice
its a useless tool . But if you have the patience and diligence to understand how it works and use it properly, its a good tool. However, in my case, 5 layers of bottom paint
are completely masking the true state of the hull
. The entire bottom is pegging. So I am getting readings on the inside which are more useful. But even that is not without pain. If surface is not perfectly smooth, for instance, PO's bilge paint
runs, it causes CT-33 to give low reading where its actually picking up air in portion of the sensor plate. So in reality i would have to sand the bilge
paint runs to get a reading. For outside, I was able to get more meaningful readings using the cheap
Home Depot moisture meter that costs 30$.
