Key Features


Automatic Depth and Current Index measurements located on all screen modes allows operators to locate on the move.

Two Gain Control Modes

Features both semi-automatic gain ideal for congested environments and manual gain for increased speed and productivity.

New Locating Mode – Peak/Null

In addition to individual Peak and Null screens the combined Peak/Null operator friendly screen, at a glance shows high accuracy peak data combined with high speed null mode data simultaneously.

Utility Direction

The new compass icon feature quickly identifies the direction of the utility path in reference to the receiver which allows direction changes or intersections to be quickly and accurately followed.


Continuing McLaughlin’s heritage of strong accurate induction locating allows for quick painless verification of marks or proposed excavation sweeps without any hookup required.


Innovative clamp design that can be attached to utility, does not need to encompass it. Exclusive one size fits all coil clamps that are completely waterproof.


3 Year warranty including water damage. Robust construction and rubber mounted internals equate in an instrument that never needs calibration.
