Unfortunately money restraints mean I can't get a refractometer at the moment, so it comes down to a choice between these:-

The Aquamedic Salimeter, Instant Ocean Hydrometer (dunk in and scoop water out type with needle), or Waterlife Seadrometer.
Just wondering which is the easiest to use out of those 3, and most accurate?
Thanks for any help guys.
