# Blog Posts and Case Studies from AGI
[AGI](https://www.agiusa.com/) (Advanced Geosciences, Inc.) - maker of our mighty [SuperStingR8](https://www.agiusa.com/high-speed-2d3d-resistivityipsp-imaging-system-package-112-electrodes) electrical resistivity meter. We also have a *Syscal Kid Switch* electrical resistivity meter from [Iris Instruments](http://www.iris-instruments.com/).
AGI's full blog is [here](https://www.agiusa.com/blog).
