The vLoc3-5000 from Vivax-Metrotech builds on the revolutionary design cues and criteria of the new vLoc3 series. The vLoc3-5000 utilizes the all-new Triaxial 3D architecture and offers class-leading ergonomics and a 4.3" color LCD perfect in direct sunlight. The vLoc3-5000 offers as standard an internal GPS w/SBAS with 2.5m accuracy for data logging and optional Bluetooth for use with the VMMAP phone application and supports external GPS receivers for mapping applications. Other unique features include SiS (Signal Select) frequencies and a colored signal distortion meter. The vLoc3-Pro screen layout is included.

Need to locate marker balls? Every vLoc3 locator can find EM markers using an optional Marker Locate Adapter (MLA).

  • Fault-Find mode ready (requires optional accessory)
  • EM Marker Ball mode ready (requires optional accessory)
  • TX LINK mode (requires optional factory order)

The vLoc-5000 features SIS (Signal Select) with Positive Line Identification. The SIS feature when used, synchronizes the transmitter and receiver to provide a direction indicator (+ or -) of the signal to be displayed on the color screen while locating. This information allows for a user to more easily determine if they are locating the correct target utility or the wrong utility. This feature is used primarily for high value utilities in congested areas, i.e., running through crowded corridors, etc. SIS can be used in low and medium frequencies making the vLoc-5000 one of the most accurate line locators ever developed.

Classic Locate Mode
The classic mode with Peak (bar-graph & numeric indication) and Null (left/right arrows) with automatic depth & signal current and Compass (line orientation). Distortion is indicated by bar-graph color.

Green - good locate signal
Blue - some distortion detected
Red - very high distortion

My Image

Signal Select (SIS) allows the target line to be positively identified by indicating a (+) Plus "positive" indication of locate.

When the (+) Plus is indicated, the user can be sure that they are locating the target utility.

My Image

When the Signal Select (SIS) displays a (-) Minus or negative, this indicates that the user has lost the initial target locate and is now locating the wrong utility. This feature alone can save thousands of dollars in miss locates and lost hours on the job site.

Cal Verification 
Stacks Image 3479
Calibration Verification / Self Test
No more "Cal" timer or cost associated with reseting a timer. This built-in Calibration Verification Self-Test is both complex and comprehensive and new to the industry. This feature virtually obsoletes the need to return or purchase a plug-in-to-paper validation certificate.

  • High integrity self test that assures the sensors are operating within factory tolerances.
  • Result measurements are compared to initial factory calibration tolerances.
  • Passing the self-test assures that the locator is within factory calibrated performance criteria.
  • Self-test results are logged to an internal SD card.

Warning / Alerts
Warnings and Alerts provide users with instant feedback when something is wrong. These events will cause the handle to vibrate as well as display a visual notification indicating type of alert. All events are logged onto an internal SD card for future reference.
My Image

Shallow Depth Warning
This warning occurs when the utility detected is less than (6) six inches deep. This can prevent damage from occurring to the utility and provide user safety.

The Loc3-SIS broadband high power transmitter offers high output current (up to 1,000mA RMS constant) and offers all frequencies between 98Hz to 200kHz, SD mode (Signal Direction), (8KFF) fault-find, (SIS) all available Signal Select frequencies and an accurate resistance measurement up to 1M Ohm. The ruggedized and lightweight ergonomic design provides direct connection, signal clamp or induction mode and is protected against incoming voltages up to 240V. The LCD display with LED backlight displays output current, connection type, volts, resistance, frequency, volume, battery condition and high voltage warning.

If equipped with optional TX LINK, the transmitter can be remotely controlled by the vLoc3 series receiver. The range is typically 985 ft. (300m).

The TX LINK is an optional feature and requires the transmitter radio link to be installed on both the Loc3 transmitter and vLoc3 receiver. TX LINK allows the transmitter to be remotely operated from the receiver. When linked, changing the frequency on the receiver will automatically change the frequency on the transmitter. The range of the radio link depends on having a clear "Line of sight" between the Receiver and Transmitter and is typically 984 ft (300m).

Using TX LINK with the vLoc3 series Rx is as easy as pressing the frequency key ("f") to change the frequency. For additional operations simply enter the "Transmitter Control" screen from the normal menu mode. This screen will display a visual of the transmitter display itself and allow user to increase or decrease power output (+ or -).

The Transmitter Control screen will display the following:
Radio link signal strength (40% as indicated).

Output mode icon (direct connection)
Output signal frequency (640Hz)
Output current (100mA)
Volume setting (level 2)
Transmitter battery level (Full)

Pressing the ("I") button will return to normal locating screen.

If TX LINK is not necessary, simply "Disabled" on both the transmitter and receiver to conserve battery.
