Aren't they pretty much all the same?

[flipside]

Yup. They are all the same. Some are easier to read than others, but they all calibrate the same, as well as serve the same purpose.

I have the Marine Depot Pro Refractometer and also the C-Scope from JBJ. The Marine depot costs more, but I prefer the JBJ since the display is much larger and easier to read. Basically, they all do the same thing and will give the same results if calibrated the same. I would get the cheapest one out there or a used one since they really can't "go bad" or give false readings if calibrated correctly.

Which ever you get, buy a small bottle of calibration fluid. If you don't calibrate it you are blindly mixing saltwater. I have seen them off on their readings quite a bit when I have calibrated them.

thanks for the heads up!

The MD one doesn't have calibration fluid. You use RO water to calibrate it.

[madehtsobi]

i think I'm just going to go with the ebay one...comes with the solution too...

[Andy]

The calibration fluid is around 5.00. I think it calibrates to 1.026 which is alot closer to the reading we are looking for than 0. Just my opinion.

I always find that I have to recalibrate before every use. When I was diving off the coast of hawaii in June, I filled about 8 water bottles worth of sea water. I now use that as calibration fluid.
