Yeah, please update your current ways of salinity measurement. I didnt even know they still made hydrometers. Prevent a headache and buy a refractometer.

Is this the "recommended brand". I also checked out MarineDepot, and they have ones that range in price from $50-$120. How much should I be spending on a good quality, accurate refractometer? Why such the big gap in price? Quality or just bells and whistles?
