Got sick of that ceap plastic Sg meter that would never read the same result twice.

I dialed this one in using that salinity soultion I got aswell. My SG results are dead on now for sure.

Inside of the box

Came with the screwdriver dial in the reading. Also has a little eye dropper. All you do is drop 4-5 drops onto the end of it. Put the plastic window down and looking into the other end. You will see blue and white. Where the blue meets the white you read the SG and thats it.
