Smart vs. analog

Smart markers (RFID, e.g., SM1500): passive with a unique ID—ideal for strategic points and records.
Analog EMS markers (e.g., MiM/Marker 120, Marker 2500/Long): proven, maintenance-free solution for permanent point marking.

Form factors & use

  • Ball markers (MAR 100-3D): self-orienting for a distinct locate response.
  • Disk/low-profile (MiM/Marker 120, Marker 2500/Long): installed horizontally; options for standard and deeper cover.

Selection & installation

  • Match frequency to the utility (water, power, telecom, sewer).
  • Place the marker centered above the feature; observe orientation by form factor.
  • Consider soil/depth; use deep variants for greater cover.

FAQ

When to use Smart vs. analog?
Smart with unique ID for identifiable points/data; analog for robust standard marking.
How deep can they be located?
Typically up to ~1.5 m; deep versions up to ~2.5 m depending on model and conditions.
Which form factor should I pick?
Ball for self-orienting point marking; disk for flat installations and deep variants.
