Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Hello
I would stay away from the Neptune salinity probe. They are notorious for being out of calibration. I would buy the new Hanna salinity checker. Or anything else but Neptune apex salinity probe.
But if you do buy it buy it new. That way at least you have a warranty.
