We offer service, upgrades, and trade-ins for your orphaned Bison Instruments resistivity and seismic products. They were designed by current GISCO employees! Don't let the end of Bison Instruments make your investment go to waste.

GISCO offers service and replacement parts for a wide variety of instruments. We can also supply connectors, chart paper, batteries, and many other parts you may need for obsolete, discontinued, and orphaned instruments. If we do not have it we will find it for you.
