Magnetometer rental, Australia
Rent the best ground mag kit in the country
GEM Systems potassium (k-mag) and Overhauser magnetometers, fitted into the lightweight backpack we designed after thirty years of walking the line ourselves. Built-in navigation, no cables to snag, and a geophysicist on the other end of the phone.
The backpack
Designed by people who walk the line
Off-the-shelf magnetometer packs were built around the electronics, not the operator. Ours was built the other way round. Our crews have walked thousands of line-kilometres in it and cover about 20% more line per day than they do in a manufacturer's pack.
Nothing to hook a tree
A non-magnetic GPS antenna and short carbon-fibre poles keep the sensor at or below head height. Cables run inside the pack.
Navigation built in
The GEM console guides you along the line, so there is no noisy handheld GPS and only one operator per magnetometer.
Light on your back
Lithium batteries instead of lead acid, an internal aluminium frame and a hydration pouch, on a harness from an Australian hiking brand.
Protected and serviceable
A pouch shields the console from scratches. Spares for every critical part travel with the pack, and more are on the shelf here.
The instruments
The most sensitive field magnetometer you can rent
Every pack goes out with a GEM Systems magnetometer. We chose GEM for our own contracting work because they are simply the best available, and we are the official GEM Systems reseller in Australia.
GSMP-35 potassium (k-mag)
Four times more sensitive than a G858/9 and ten times more than an Overhauser, with a 0.1 nT heading error and high gradient tolerance. The pick for gold, iron ore and mineral sands.
GSM-19 Overhauser
The dependable workhorse for regional and reconnaissance grids, with the same built-in navigation and the same backpack.
Base stations, VLF and spares
A second console for your diurnal base station, VLF add-ons that integrate with GEM magnetometers, and batteries, chargers, cables and antennas in stock, shipped fast if you are stuck in the field.
