Fisher FML-3 Magnetic Locator

Fisher FML-3 Magnetic Locator

The Fisher FML-3 is a high-sensitivity magnetic locator engineered for professional field applications. This system is manufactured in the USA featuring the best technology in locating. The FML-3 locator utilizes fluxgate magnetometer technology to detect ferrous objects. These objects could be valve boxes, manhold covers, PK nails and more. One of the most beneficial features is its one-handed control allowing for flexibility in tough jobs. This system is also waterproof and includes polarity recognition.

Structural Design and Durability

The FML-3 locator has been engineered with aircraft-grade aluminum and includes a waterproof sensor tube tested to a 220 feet depth. This system was crafted with the toughest materials for the most reliable operation. With resistance to impact, dust, and moisture ingress, the FML-3 is designed for sustained field deployment in utilities, surveying, and construction.

Control and Interface

The instrument features a four-button keypad that provides direct access to all operating functions:

• Power on/off
• Gain control for sensitivity adjustment
• Interference suppression for high-clutter environments
• Zeroing function to eliminate ambient magnetic field bias

One-handed operation allows technicians to maintain efficiency in confined spaces or while navigating challenging terrain.

Detection Method and Feedback

The FML-3 provides simultaneous audio and visual outputs for precise target acquisition.

• Audio output: Pinpoint buried ferrous objects rapidly with the FML-3. The frequency of tone increases proportionally with magnetic field strength.
  
• Visual output: LCD displays signal polarity, relative strength, and low-battery condition. Polarity indication enables accurate identification of cast-iron joints and discontinuities.
  
• Depth capability: Detects ferrous objects at depths up to 8 feet depending on target mass and soil conditions.
  

Power and Field Readiness

The locator is powered by standard alkaline batteries with extended runtime for full-shift operation. A flashing low-battery warning is integrated into the display to prevent downtime. The unit ships with a padded carrying case and straps for secure transport and protection during field deployment.
