Borehole survey instruments and full lifecycle support — gyro, magnetic, core orientation and gamma logging, supplied, rented and kept running in the field.
Magnetic methods fail inside steel and mineralised ground — gyroscopic north-seeking is the backbone of accurate azimuth in mining, and the core of our offering.
Spectrum equips mineral exploration and drilling programs with the directional survey instrumentation they depend on — from north-seeking gyro tools that work inside casing, rod and magnetic rock, to magnetic multishot probes, core orientation modules, natural gamma loggers, rig alignment systems and the depth-measurement and conveyance hardware that ties a survey program together. We pair a complete trading catalogue — sale and rental of slimhole, all-angle and blast-hole instruments — with a regional service capability covering calibration, repair, overhaul, field deployment and operator training. Because magnetic methods fail inside steel and mineralised ground, gyroscopic north-seeking is the backbone of accurate azimuth in mining — and it is the core of our offering. Everything is supported locally, so downtime, lead times and freight exposure stay low.
New instruments for sale and rental, plus consumables, conveyance hardware and software licences. Where a hard specification is published we list it; where a figure is application-dependent we describe the capability and confirm exact specs per model at quotation.

A survey instrument is only as good as its last calibration and its uptime. Spectrum provides the full post-sale lifecycle so tools stay in-region, in-spec and in the field.
Stocked and serviced in Oman and the Gulf — shorter lead times, lower freight, and in-region calibration and repair turnaround.
Gyro, magnetic, core orientation, gamma, alignment, conveyance and software — from one source.
Accurate azimuth inside casing, rod and magnetic rock, where magnetic methods fall short.
Outright purchase or rental, with fleet support for contractors running campaigns.
The team that supplies the instrument also calibrates, repairs, trains on and supports it.
Our capability is built on strategic partnerships with leading OEM principals and an intelligent, vetted supply chain — bringing proven equipment, technology and engineering to the Gulf under one accountable contract, sourced to spec and delivered to schedule.
