 Microprocessor control of discrimination and auto ground balance.
- Automatic sound discrimination of metals during searching - high tone for non-ferrous metals and low tone for ferrous metals /lodestone/.
- Regime of work only for non-ferrous metals. The metal detector doesn't react to ferrous metals. This regime allows to be worked faster and effective compare to apparatuses with arrow indication and is very suitable for dirty soils.
- Manual or automatic filter for eliminating earth influence.
- Additional filter for tuning to high mineralized soils.                                           
- VCO regime for the exact localization of the found object.
- Automatic tuning to temperature changes.
- High stability of the electronic unit to electromagnetic disturbances. (transmission lines, radars, etc.)
- Setting of sound.
- Blinking red indicator for exhausted battery.
- Work frequency - 12,5 kHz
- The metal detector is partly air - proofed and can be deluged into water till the end of the box. When searching single coins it can shows their situation in soil: horizontally and vertically.
- Supplying of NRG-100 is equipped with accumulator block of 12V and automatic charger for it. Charging is easy without taking out the batteries off the detector. It is also possible to be plugged in outer re-charge set.
- Time of work once charged is about 12 hours, and if using outer re-charge set - 60 hours!
- Weight of the metal detector fixed up is 1,5 kg including batteries.
- Each detector is supplied with a user's manual.
- The metal detector an be purchased with one ore more search coils. 27cm. in the set. When buying NRG-100 together with two ore more search coils you will get  headphones FOR FREE!

Stinger 2 is an impulse metal detector with LCD display, digital and graphical presenting of the level of signal and parameters of discrimination and working regimes, such as state of temperature of the battery.
- Full microprocessor control that assures stable work in every soil conditions
- Full automatic balance to earth conditions, remembering and adapting to the level and parameters of soil and eliminating of the common signal.
- Two ID indications for the characteristics of the found metal - non-ferrous metal properties and magnetism.
- Discrimination modes - “Normal discrimination” - for normal soils and 8 modes “Auto discrimination” for highly mineralized soils with the capacity to change its range in wide limits and outside noises, also for accept / reject of metal objects.
- Ability to store and completely eliminate strongly mineralized soils, heavy soils, active ceramics and slag.
- Unique ability to find non-ferrous metal among iron objects or under active ceramics and heavy soils.
- Ability to eliminate completely undesired objects.
- Ability to store a certain type of metal and to find only this metal and exclude the rest.
- Eliminating the influence of earth magnetic field and bringing it out of the common signal.
- Eliminating the secondary disturbances during working process.
- Possibility to work in rooms and close to electrical networks - full suppressing of 50 Hz disturbances.
- Ability to choose among 8 speeds: 4 dynamic (with motion) and 4 static - for the exact localization of the object.
- Choosing of 2 types sound indications - VCO /much frequency/ or two tone indication - low tone for ferrous and high tones for non-ferrous metals.
- Regulation of the power of radiating impulses.
- Regulation of the discrimination.
- “Working time” indication to battery discharge.
- Backlight LCD - 7 levels
- Built in accumulator battery 18V / 2800mAh, that can assure 8-12 hours continuous work depending of the chosen power /100-300 W/ and the type of the search coil /frame/ used. It is possible to be plugged in outer supply block which can be carried around the waist or in a bag and which is also accumulator battery and can be charged with charge set. Its working time is about 40-60 hours!
- Automatic charging - measuring of capacity and pointing the temperature during charging,
- Possibility for adjusting of over 40 work and additional parameters assuring comfortable and effective work in different conditions of searching.
- Quick and easy access to all adjustments in the menu.
- All these advantages allow Stinger 2 to be used for working in every condition including heavy mineralized and dirty soils!
Stinger 2 can work with searching frames 1,20x1,20 m, 2x2m, round coil 36 cm with handle and 22x32cm. with handle.
Depths of finding metals with searching frame 1,20x1,20m.:
- metal object sized: 10 x 10cm………………….180 cm. (5,5')
