Vivax-Metrotech · Complete Locator Kit · 850-F001-H
The 9.82 kHz kit for CATV, telephone, and power: the VM-850 receiver, a rechargeable Li-ion transmitter with charger, leads, ground stake, and hard carry case under one order code.
Demonstrated before you buy, set up and trained on delivery, and supported by Intermountain Sales for the life of the locator.

The VM-850 transmitter
A low frequency like 9.82 kHz takes more power to drive onto a line than the VM-810's 83.1 kHz. Vivax-Metrotech built the VM-850 transmitter around an internal rechargeable lithium-ion battery for exactly that reason, so you are not burning through D-cells on long CATV and telephone runs.

Applying the signal
The VM-850 transmitter supports direct connection, clamp, and induction, so one kit covers everything from a drop at the pedestal to a long run in conduit.
Safety: the transmitter output can reach 65 volts RMS. Turn it off before connecting or disconnecting leads.
The kit in action
Put 9.82 kHz on the cable with the transmitter, then walk the line with the receiver. The Left/Right meter and tone walk you onto the cable.
Full receiver details are on the VM-850 Receiver page.

View productThe Intermountain Sales difference
As the oldest Vivax-Metrotech distributor in the United States, we have sold, trained on, and serviced these locators for decades. Before you buy a locator kit, we will ask what you locate, where, and how often, and point you to the tool that fits your crews and your budget. Sometimes that is a simpler, less expensive locator, and we will tell you so.
We bring the locator to your yard or jobsite so your crew can run it on your own utilities before you commit.
We recommend by application, not by price tag. If a lower-cost locator does the job, that is the one we will quote.
On-site training at delivery, refresher training for new hires, and help whenever your crew needs it, for the life of the product.
Repairs, calibration questions, and technical support from people who use these locators, for as long as you own it.
Find the right fit
Frequency matters. The right VM locator depends on what you are tracing and how it is buried. Not sure? Call us and we will help you choose, or bring one out for a demo.
