The SBL10 is a very compact handheld device for detection of ferromagnetic objects in the ground. With only 3.7 kg and a clearly arranged control display, the SBL10 is easy and intuitive to operate. Due to its folding mechanism the SBL10 needs no assembly and is ready within seconds.

When being used with an additional probe FGM400/38 and cable (simply connected to the top of the SBL10 control unit) the device is ready for borehole or underwater surveys.
The measurement range of both probes is ±30,000nT and enables detection of smallest pieces as well as of deeply buried heavy objects in depths of five to six meters.
Three different modes allow for surveys on clear or noisy ground as well as in front of fences or rails.

Two battery compartments are used in sequence with an intelligent power management to ensure more than 100 working hours with only one set of standard LR20 batteries.

The connection of the additional probe as well as wireless connectable rugged PDA for data recording always keeps the SBL10 as slim as possible but as flexible as needed. Furthermore, the SENSYS MonSX software on the PDA for data recording also allows for an instant view of the covered field as color coded map. that allows a first intepretation of the operator whilst in the field. On top, all parts fit into a light weight fully rugged casing that is easy to store and transport.
