Service & Parts

We provide service and spare parts for all brands we sell.

GISCO offers service and replacement parts for a wide variety of instruments.  We can repair or upgrade most geophysical 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. If we can not find it we may be able to make it!

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 also buys and sells used equipment. If you don't see what you need on this list -give us a call- 
we can probably find it for you. GISCO accepts trade-ins on equipment purchases.
