Anyone use one?

I would not trust how it measures salinity it uses conductivity to measure it. I feel that could be and issue since other things can effect conductivity.

Kinda what I thought.. Too bad. Would make life a lot less complicated...

is there anything else electronic that would measure salinity?

Is anybody using Pinpoint meter or is it only for low-salt gold fish ponds?
