Whats a good refractometer?

[mfin77]

I am looking into buying a refractometer, however there are too many to choose from.

What does everybody recommend?
Hows the one from marinedepot or bulk reef supply? their both pretty affordable.

Are the ones for $100 really that much better and easier to use?

Thanks,
Mike

Try to buy a used one on MF first.I was lucky enough to buy one from a member last week.Any refractometer is better than no refractometer imo.

Make sure to get one with ATC (automatic temperature compensation). Most for reefing purposes can be found under $40.

[Deanos]What does Automatic Temprature Compensation actually do?

Refractometers

Also, from the internet:

If using a non-ATC refractometer, as the temperature increases, accuracy of the reading will be compromised.
