i did this test to represent a surface to static water depth measurement by continuity. the continuity meter is a sounding device $20.00.
i grounded to the coffee can and connected my red lead to the wire which i inserted in the water.
the green light shows that we are powered up, the unit beeps and the red light flashes for continuity.
i should be able to actually use this in the field next week.
right now i need to clean some ditches.
