vScanS - standard model of underground communication locator from Vivax-Metrotech, USA.

The vScanS standard model performs all 3 basic functions of an underground communication locator:
1. finds communication,
2. identifies communication,
3. determines its installation depth.

- For passive communications (disconnected power and communication cables, optical cables with a signal core, metal pipes), the vScanS receiver requires a vScanTx generator in order to provide the above three basic functions.

- For non-conductive communications (plastic water pipes, plastic sewage pipes, etc.), the vScanS receiver requires a push cable with a 33 kHz sonde/transmitter as an auxiliary.

vScan specifications:
Passive modes: Power (power cables), Radio (communication cables), CP100 (for pipelines with cathodic protection)
Active frequencies: 33kHz, 131kHz
Sonde mode frequencies: 640Hz, 33kHz
Practical depth measurement: up to 7m
Depth measurement accuracy up to 3m depth no worse than: +/-2.5% of depth
Depth measurement accuracy above 3m depth no worse than: +/-5% of depth
Horizontal accuracy up to 3m depth no worse than: +/-3% of depth
Horizontal accuracy above 3m depth no worse than: +/-5% of depth
Current measurement accuracy no worse than +/-5% mA rms

Indications:
Audio, vibro and bargraph
"Compass" indication for determining the direction of communication
Measurement modes:
     - Depth of installation
     - Current in communication
Battery status indication
7 types of warnings
Bluetooth status (only for vScanB models)
GPS status (only for vScanG models)

The following vScan versions are available:
- Standard receiver - vScanS;
- vScan series receiver with metal detection as an additional function - vScanM;
- vScan series receiver with built-in GPS as an additional function - vScanG;
- vScan series receiver with built-in Bluetooth as an additional function - vScanB;
- vScan series receiver with built-in GPS and metal detector as additional functions - vScanMG;
- vScan series receiver with built-in Bluetooth module and GPS receiver as additional functions - vScanBG;
- vScan series receiver with metal detector function together with built-in BT and GPS modules as additional functions - vScanMBG receiver. 
vScan user interface and control are intuitive and meet industry standards, but new features help the user to quickly and accurately achieve excellent results, as well as save the collected data. The functions of the receiver/locator can be configured using the MyvScan SW, which also provides data transfer and management.

vScan application:
•   Find, track and measure the installation depth of underground pipelines and cables;
•    Find, track and measure the installation depth of non-metallic pipelines using a probe;
•   Save measurement data: measure the required parameter and save it together with location information (vScanG, vScanMG models);
•    With the vScanM version, find buried, covered or asphalted iron covers, valve covers, etc.
•    With the vScanG, vScanMG versions, record the coordinates of the measurement location and save them together with the measurement data in the receiver's internal memory for further transfer to the user's computer.

Typical users:
•    Geodesists, topographers, surveyors;
•    Municipalities, railways, local and state government agencies;
•    Utilities and communications companies, communication network maintainers;
•    General contractors, construction and communications maintenance companies.
