Lorenz Deepmax Z1 Metal Detector
with 14" (35cm) DD Search Coil and 40x40" (1m x 1 m) Frame Search Coil.
The Lorenz Deepmax Z1 series of detectors are some of the newest developments in the field of Pulse GBS metal detectors. It is probably one of the most sensitive and stable metal detecting devices of its kind presently available. The Lorenz Deepmax Z1 is the result of many years of research and development. A lot of effort has been put into making this new product, and especially in the new and improved metal classifications and automatic ground balancing facilities.
The Pulse GBS (Pulse Ground Balancing System) is especially suitable for searching at depth. The performance of this electronic device is almost unaffected by salt water, most types of mineralized grounds or temperature changes. Specially designed electronics cancel out signals from the ground while offering stable signals from the metal objects. The Deepmax Z1 is therefore a reliable tool to locate at great depths even under the worst environmental conditions. A newly improved circuit design suppresses interference from power lines and a power pulse technique produces very accurate signals to obtain very high detection depths.
The Lorenz Deepmax Z1 is a high quality specialist detector and it is designed to be used with both, small or large coils. Large coils offer extreme depth capabilities for big metal objects because of the strong and deep going magnetic field produced. Small coils are preferably used while searching for small objects like single coins or gold nuggets.
This model offers a great range on non-ferrous metal objects in general. A very simple operation is guaranteed by a specially developed LC Display and a minimum amount of controls. At the same time, this detector model offers a number of features which are new for a pulse metal detector. Quality electronics and very specially designed electronic - circuitry produce benefits in terms of ease of use as well as sensitivity.
The Lorenz Deepmax Z1 is based on the non-motion Pulse GBS (Pulse Ground Balancing System). Short and intensive magnetic pulses are emitted by means of a search coil first. Those magnetic pulses produce eddy currents in conducting materials like metal objects. Said eddy currents will be kept in a metal object and will die away after the magnetic pulse emitted by the search coil has turned off. This is the reason why it is possible to detect those eddy currents during the time delayed receiving phase by means of the same search coil which now acts as a receiving coil. A rather complicated electronic circuitry is necessary to detect those tiny voltage changes and has to separate that particular signal from interference also received. The signal has to be amplified to drive an audio stage with voltage controlled oscillator (VCO), which emits an audible signal either by headphones or built-in loudspeaker when a metal is in the near of the field of the search coil.
