I agree. I use no open frame devices when I build marine circuits. I spray the crap out of them with several coats of clear conformal coat. This is why my model boats can run under water. Lots of practice at waterproofing stuff. Learned the hard way.:o

The battery test circuit in the Minn Kota V2 is coated.
