Only significant misgiving about the first units: The 112 module has a stray magnetic field -- per L. Frank -- of ~ 60 gamma at 50 cm. or ~ 8 gamma at 1 meter or ~ 1 gamma at 2 meters. This magnetic moment (apparently) is due to magnetization of 112 stainless steel tube when shaken in the [strong?] stray magnetic field of the shake table !!
