Using the correct frequency makes a world of difference when locating buried utilities. The depth of the utility, size, material, and amount of congestion (proximity of other utilities) all need to be taken into consideration for the correct frequency selection. Large diameter, direct buried pipes with bell housing ends that use insulators and rubber gaskets, such as water or gas require a higher frequency while smaller diameter, well-grounded direct buried or long distance in conduits work, better with a lower frequency.
The VM-810 operates at 83.1kHz which is ideal for water and gas utilities which generally are larger pipes with bell housings and gaskets. The VM-810’s higher frequency is also good for locating ungrounded small diameter drop wires and inducing signals through the soil, onto services when direct connecting is not an option.

Features
- High-frequency 83.1 kHz operation — ideal for locating large water or gas pipes, lines with insulators/gaskets, ungrounded drop wires, or when direct connection is not an option (use induction or clamp mode).
- Distance Sensitive Left/Right Guidance™ — automatically guides you to the strongest signal so you can quickly align over the buried utility line.
- Automatic gain control — simplifies locating by adjusting sensitivity in real time as signal strength changes.
- Depth and current readout — provides quick indication of how deep the utility is and signal strength/current flow for validation.
- Compact, rugged, and portable — receiver telescopes for easy transport, and the kit comes in a hard carrying case for field work.
- Multiple connection modes — direct connection, inductive coupling, or clamp modes give flexibility depending on job conditions.
- Weather-resistant design — suitable for outdoor use in typical jobsite environments.
