Page 4: General Warnings
GENERAL WARNINGS ALWAYS EXCAVATE WITH CARE C.Scope Locators detect services radiating a detectable signal. There may be some services that do not radiate a signal and cannot be located. Do not use the equipment outside of the temperature range -10˚C to +50˚C (14˚F to 122˚F) as the batteries may cease to function adequately. Geographical conditions such as hills and mountains may effectively screen signals and prevent a detectable Radio signal. -

Page 7: Locator Operating Modes Power Mode
Locator Operating Modes: Power Mode In Power Mode the Locator detects power signals. These power signals are present on all current carrying electricity cables although not all are detectable. Power signals may also flow along other conductors such as metal gas and water pipes, telecom cables, metal fences and railway tracks. -
Page 8: Radio Mode
Locator Operating Modes: Radio Mode In Radio Mode, the Locator detects signals from various radio transmitters. These signals flow through the ground and will tend to follow the line of least resistance such as a buried metallic service. When this happens the service can often be detected by using the Locator in Radio Mode. -
Page 9: Generator Mode
Locator Operating Modes: Generator Mode In Generator Mode the Locator detects conductors radiating a signal Direct Connection applied by the Signal Generator or the signal radiated by a Sonde. The Signal Generator provides a way of sending a known signal along buried metallic services which can then be detected using the Locator. -

Page 12: Searching
Using the Locator: Searching There are three stages to the locating process; searching, pinpointing and tracing. 1. Turn the Mode Switch to the appropriate mode. 2. Hold in the On/Off trigger. The Locator should emit the audible battery test tone and the digital display should come on. Check the battery level indicator to confirm the batteries are usable. -
Page 13: Pinpointing
Using the Locator: Pinpointing Having found a signal the next step is to pinpoint the source. The closer the Locator is to the signal source the stronger the response. To Pinpoint a Signal 1. Keeping the Locator vertical, walk through the area of the signal response. -
Page 14: Tracing
Using the Locator: Tracing Having pinpointed a service it should now be possible to trace its route. 1. Carefully follow the direction of the signal holding the Locator at right angles to the line of the signal. It is necessary to constantly ‘slice’ the Locator from side to side in order to be sure of still being over the peak signal response. -
Page 15: Using The Signal Generator
Using the Signal Generator Using the Locator in Power and Radio Modes will only allow you to locate and mark the position of buried services that are producing a Power signal or re-radiating a Radio signal. Use of the Signal Generator should enable most, if not all, of the remaining buried metallic services to be detected and traced. -
