Full Product Info

Features and Specifications:

• One-hand operation
• Easy keypad switches, no knobs
• Lightweight – only two pounds (including batteries)
• Uses two regular alkaline 9-volt batteries
• Strong monotube construction provides structural integrity
• Microprocessor retains volume and gain settings from last use
• Soft pack carrying case and hard case included
• Lifetime warranty
• ML-1 is a non-metered device (audio only).
• ML-1M additionally features a digital meter that provides for visual signal strength, polarity indication, gain setting plus battery life display. These versions are engineered to operate identically with the same controls. The metered model (ML-1M) adds features without adding complexity.
• Use these magnetic locators to find:
  • Corner markers (iron or steel)
  • Mag nails and PK nails
  • Valve and curb boxes
  • Iron and steel pipes
  • Well casings
  • Manhole covers
  • Steel drums & tanks
  • Septic tank handles
  • Energized electric cables
  • Marker magnets
  • Unexploded bombs (UXO)
• Made in the USA
• Here are some rules of thumb to how far down your magnetic locator will be able to detect objects:
  • PK Nails: 6" to 18" (depending on size of nail)
  • MagNails: up to 36' away depending on size of nail
  • Valve boxes, Curb boxes, etc…. 4' to 8' depending on % of steel or iron contents
  • Surveyor Corner Markers: 5/8" x 18" steel rebar up to 20' deep
  • Well casings up to 30' or more deep
  • Steel or iron water or gas pipe, lying horizontally: 4" pipe, 4 to 6 feet; 8" pipe, 8 to 10 feet, etc.; with "peak of signal" at joints
  • Sewer/utility lids of cast iron: depends greatly on the structure the lid is capping/covering: 2' to 20' or more (the vertical casing the lid is covering may be stronger than the cover)
• Keep in mind: any object lying on it side (oriented horizontally) will be weaker than if it were lying in a vertical position
  • An object lying horizontally will have at least two "peak signals" (one directly over each end)
  • An object oriented vertically will have one STRONG signal directly over it
  • An object oriented vertically in the Northern Hemisphere will be stronger if the Negative end (-) is pointed up, rather than the Positive (+) end
