the operator.
MR-10 Magnetic Locator Safety
• Do not place the Magnetic Locator any-
where electrical contact may occur. This
increases the risk of electrical shock.
• Locating equipment uses magnetic
fields that can be distorted and inter-
fered with. Utilities may be present in a
given area. Follow local guidelines and
one call/call before you dig service pro-
cedures. Exposing a utility is the only way
to verify its existence, location and depth.
• Do not use for locating explosives, ordi-
nance or other hazardous materials.
• Avoid traffic. Pay close attention to moving
vehicles when using on or near roadways.
Wear visible clothing or reflector vests.

Description
The RIDGID
®
MR-10 Magnetic Locator is a
highly sensitive handheld locator specifically
designed to detect the magnetic field from fer-
rous objects, such as buried curb stops, prop-
erty markers, valve boxes, manhole or vault
covers, well casings, and other iron and steel
objects.
The locator responds to the difference in the
magnetic field strength between two sensors.
The Magnetic Locator provides an audio sig-
nal, and visual indications of both signal
strength and polarity on detecting presence of
a ferrous object.
