The digital refractometer is certainly easy to use and read, but it could be better in two ways. 1) It's huge, which makes storing and manipulating it with one hand (like you would with a standard refractometer) difficult. 2) It's precision is no better (and a little worse than the MD Pro refractometer). It reads salinity in whole numbers (34, 35, etc) and SG down to only thousandths (1.028). Seems like for the cost you should get another digit of significance. It's main selling point is it's digital, albeit low resolution, display.

This is another winner which takes the guess work out of reading salt water salinity. By pushing two buttons (on/off and read button) you get an instant accurate reading which takes the sample temperature in consideration. You probably want to also get the carrying case as part of the package deal, I did.
