Overview
The Phoenix Geophysics Ultra-Wideband Magentotelluric (UMT) system consists of a 5 channel UMT receiver (MTU-5C), three MTC-150/155 induction sensors and porous pot electrodes.
We also have available titanium plate electrodes and preamplifiers for use in highly resistive snow and ice environments.
The GEF currently have 5 systems available for loan. View our schedules to see equipment availability.

Courier to a UK destination
The GEF(Edinburgh) will ship loan items to the borrower by courier to UK addresses on a next day basis free of charge. It is the borrowers responsiblity to return the equipment to the GEF, on time and at their own expense via any suitable means.
Please note some GEF equipment uses Lithium Ion batteries. You may need to use a road based courier to return equipment to us, please contact us or see our guide to shipping lithium batteries for further information.
Collection from the GEF
Borrowers may collect and return equipment in person from the GEF offices (in Edinburgh and Leicester).
Shipping outside the UK
The GEF(Edinburgh) only ships to destinations within the UK. It is the borrowers responsibility to arrange transportation and all necessary customs paperwork for any temporary export and re-importation to the UK. You may arrange your own courier to collect equipment from our offices.
User training
New users of our GNSS equipment are required to be trained by Facility staff. Training usually takes place during a one day visit to the GEF offices. Previous users are encouraged to attend for refresher training.
Successful applicants will be invited to contact the Facility to arrange a suitable training date, usually close to the start of the project.
Training is free of charge, however applicants will be responsible for making their own way to the Facility.
Frequently asked questions
Do you supply batteries to power the MT systems?
No, the GEF does NOT supply batteries for these systems. You will need to supply your own 12V batteries, typically lead-acid car type. Depending on the deployment length required, these are typically rated from 40Ah to 100Ah.
