I will also add that in a cooler with 65% beads, the hydrometers (diamond crown) read exactly 65...so something must be wrong with my set and forget as two other devices reading dead on using beads and salt test, contradicting the set and forget......
But the set and forget is accurate (consistently the same wrong number) just not precise (same and correct number) and keeps the same numbers so I just note the difference and keep an eye on it for any drift in tthe readings
