The ORX offers settings of: '1', '2', '2.5' and '3'. I have no clue why they used '2.5' and didn't just go,: '1', '2', '3' and '4'.

Anyway, there is no '4' or '5' and I have found several cases where a setting of '3' will cause you to lose some desired targets. I hardly ever use an ORX above a setting of '2'. That's usually quite ample for most iron contaminated sites.
