An initial plan to demo of the Geometrics Atoms 3Cs by Koichi Hayashi has evolved to an opportunity to informally compare records from the Geometrics Atoms (with 1C & 3C receivers: 1 Hz?), Geometrics MT-Neo, current- & older-generation Trominos, & the USGS Trillium120/RT130. I”m crossing my fingers (& toes) as I have asked IRIS-PASSCAL to send a Fairfield 3C Nodal, which if luck holds, is expected to arrive on Friday before 8:30 a.m.
