Rated 5 out of 5 by Scotz Very easy to use and very accurate
I wanted a very simple, easy and accurate instrument to quickly get my salinity readings. You will need to verify the calibration of the instrument using the bottle of calibrated solution (included) before you first use it. It takes an screwdriver made for eye glasses to adjust the screw (not included). After calibration, simply wave the wand in the water and wait about one minute for the unit's temperature calibration to stabilize. You will have an accurate reading that is repeatable. Yes, it costs a little more than other types of salinity instruments, but I feel it is worth the extra I spent.

This little jewel is proving to be incredibly accurate, and the ease of use is phenomenal. It's hard to know what machines and/or tests to trust to accurately care for thousands of dollars in fish and corals, but I give this one five stars!!!!*****

Rated 4 out of 5 by volleyb it just works
Was pretty easy to set up and it seems to be very accurate. I know I will never use a plain hydrometer again.

Rated 3 out of 5 by GM0NEY Requires constant calibration
Needs to be calibrated between each reading, if you have two tanks you will need to calibrate it twice to read both tanks salinity.
Get a refractometer.
