Mark joints, tees, bends and crossings permanently. Tempo ball and disk markers provide a clear locate response and dependable range for confident field identification.
- Omni Marker II (ball) & Uni Marker (disk)
- Utility-specific frequencies (e.g., 92.0 kHz fiber, 101.4 kHz telecom, 121.6 kHz sewer, 134.0 kHz power, 145.7 kHz water, 83.0 kHz gas)
- Typical burial depth up to ~1.5 m (model dependent)
- Self-orienting ball markers for pinpoint accuracy
- Rugged designs for long-term underground use

Ball & disk form factors
Omni Marker II (ball): self-orients during installation, ensuring a distinct locate response above the feature.
Uni Marker (disk): low-profile, installed horizontally for precise point marking.
Frequencies & mapping
Choose the frequency by utility. Examples: Gas 83.0 kHz, Cable TV 77.0 kHz, Fiber 92.0 kHz, Telecom 101.4 kHz, Sewer 121.6 kHz, Power 134.0/169.8 kHz, Water 145.7 kHz.
Installation tips
- Place markers centered above the feature
- Respect form factor: ball self-orients; disk installs flat
- Account for burial depth and soil conditions when selecting models
FAQ
- How deep can they be located?
- Typically up to ~1.5 m depending on model and conditions.
- Omni vs. Uni—what’s the difference?
- Omni = self-orienting ball; Uni = flat disk for defined point marking.
- Which frequency should I choose?
- Match the utility (e.g., Water 145.7 kHz, Telecom 101.4 kHz).
