That's why I bought one. One of my swing arms kept registering lower
and lower SG, even though I was adding some salt water for the make up
water just about every other day. The other swing arm was stable, but
the two chronically disagreed.

I think the new reading is correct, but definitely higher then I'd like.
I'll start slowly bringing it down by removing a few cups of sal****er
everyday.
