FeaturesCombining the technology of the Supracon HT SQUID,the most sensitivity B-�eld sensor commercially available in the world today; EMIT SMARTem24, the world’s most advanced 24-bit, complete time-series TDEM receiver; and the high powered 20kW-40Amp, Phoenix TXU-30

• Direct B-field measurment at low frequency (0.5 to 5.0 Hz).

• Highest signal-to-noise of any commercially available TDEM system in the world.

• Essentially unlimited deep detection capability (from a mining economics consideration).

• Enhanced response from good conductors in the presence of weaker conductive formations and overburden.

• Enhanced resolution from higher signal-to-noise ultimately leads to better interpretation.

• High sensitivity and high power enables survey efficiencies and lower costs
