To fit on wastewater tank on my boat. So I can see when tank is full. If it works I will purchase one more, so I can see when it is empty as well.

Measure waste tank

I read about Gobius in a boat trade magazine, really interested in a measurement system that dis not break tank wall continuity. Installed a Pro version on a freshwater tank and a blackwater tank. Literally a 15 minute job! Worked perfectly the first time and ever since. No more guessing. See my install process and review @ www.sandavore.org
