ML-3 Magnetic Locator TS21729 The frost pin makes it

The frost pin makes it easier to start a hole in hard or frozen ground for survey stakes

this device can be updated to future NEC revisions by installing a new chip and setting the calculator to the latest settings

Allowing for faster and easier readings without the need for loosening and tightening the detector everytime it needs to be moved

This electronics only includes an internal and an external battery that powers the device up to 72 hours of continuous use

How It Works

ML-3 Magnetic Locator TS21729 The frost pin makes itThe SubSurface Instruments ML 3 Magnetic Locator 18ML 3S detects hidden or underground objects made of iron, cobalt, or nickel. Objects made of these materials are called ferrous or ferromagnetic. You can adjust the ML 3s sensitivity and block out possible interfering magnetic field signals. Look to the ML 3s LCD meter to determine when your battery is low. And use the built in micro processor memory to store your sensitivity settings for future use.
