Every locating job is different. Success calls for a unique blend

of equipment, experience, and persistence. In some situations,

a low-frequency, conductive locator will perform better than a

high-frequency, inductive locator. In other situations, the re-

verse is true.

The advantage of the low-frequency is long distance tracing

and in some cases, isolating one conductor from another. The

disadvantage is that it must be directly connected to the pipe or

cable.

The advantage of the high-frequency is that it traces poor con-

ductors, can locate short lengths better than the low-frequency,

and it does not have to be directly connected, though this method

is available. Inductive operation is much faster and easier al-

lowing the operator to move the signal to any place which is

useful. The disadvantage of high-frequency during inductive

locating is that it can place more signal on adjacent conduc-

tors, making isolation more difficult.

The 800-HL combines these two frequencies into one unit. It is

capable of both inductive and conductive modes. Sometimes

one frequency performs well where the other does not. There-

fore we made both frequencies run at the same time during

conductive mode. Also during conductive mode the high-fre-

quency no longer induces signal which helps isolate the target.

So as you follow the line you can switch from one frequency to

the other at the receiver allowing a multitude of locating options

and techniques.

The receiver has a meter to show signal strength which is help-

ful in noisy situations. This meter also aids in depth estimation.

We have also tuned the receiver’s audio feedback to produce

tones that are most audible by the human ear.

In short, the Series 800-HL Professional Pipe & Cable Locator

is a more complete and productive tool for any user.
