Gobius external holding tank sensor - anyone used the system

[tudorsailor]

Our holding tank has no gauge - surprisingly. I have been reading about the Gobius system that uses ultrasound from the outside to determine the level within the tank

Does anyone have experience of this system?

Thanks

Did one just before I went on holiday, easy to fit, not ever so pricey, it was on a 3mm wall ali potable water tank which was perfectly rectangular and already had a sight gauge so simple to check its accuracy after fitting, and it was, accurate that is.
