A Locator to meet your needs


  • A Reputation of Excellence
    When you choose a quality 3M™ Dynatel™ Locator, you get outstanding performance and reliability, along with toll-free technical phone support and a service center dedicated to excellence. Our service center provides calibration, repair, and upgrades.
  • Easy to Use
    Dynatel locators require little training and are simple to use. Digital LCD readouts and pushbutton operation make the units easy to interpret for precise locates.

    A bar graph on the receiver indicates received signal and proximity to the cable, and an automatic "memory" feature stores operator setup from previous use.
  • Smarter Locating
    3M has pioneered two methods for making your locating quicker and more efficient: EMS Markers, which mark points of interest and EMS Caution Tape, which mark the path of underground asset.

    Both systems work independently of any direct connection, and they provide a fixed, easily locatable point or path.

    The ability to find markers or path marking is available on certain Dynatel locators (indicated by either an "-iD" in the title for markers or those numbered 7000 for both markers and path locating).
