Progressive Dynamics Tank Level Gauge

[Tolly Roger]

I have an old Progressive Dynamics Tank Level Gauge for my POLY fresh water tank(s). It only shows when the tank it FULL.
Has anyone repaired or serviced one of these?
And second question..... what would be a recommended replacement gauge if it comes down to that. Thanks

I have installed the SCAD monitor on my previous and current boat's holding tanks they are not difficult to install and have worked fine.
