Upgrading to the Scuba 3s has made hot tub water maintenance vastly more consistent. Getting exact decimal readings for Free Chlorine, pH, and Total Alkalinity completely eliminates the frustration of trying to color-match manual test strips. The instant NFC sync to the phone app makes tracking historical chemical trends effortless, and the color-coded backlit screen gives quick visual confirmation of whether readings are in safe target zones. A must-have tool for keeping water balance dialed in.
Great and perfect service from Test All Water!
