Page 5: Ground Effect
GROUND EFFECT The signal of your detector will be affected by the type of terrain you are searching. Normally this effect produces an increase or decrease in the audio signal when the search head is raised from the ground. This effect can be controlled in two ways. If the search head is kept at a constant height the effect of the ground will be constant. -
Page 6: Recommendations For Use
Determining the Target Size and Depth An operator who is familiar with his instrument will be able to do an excellent job of determining object size, shape and depth before he digs. The technique is learned from careful analysis of the audio signals coming from the detector. -
Page 7: Care And Maintenance
Whilst searching it is important to remember that the search head should be kept as close to the ground as possible. This ensures maximum depth penetration. There is a maximum detection range and a large gap between head and ground reduces the effective depth of the search. See diagram 6. - Page 8 Salt Damage If you use your detector continually in a salty environment, particularly when the wind is blowing off the sea, salty air can penetrate the control box. Corrosion can occur in vital parts of the delicate electronic circuitry. It is, therefor, recommended that precautions such as covering the control box with polythene be taken to avoid damage.
- Page 9 Intermittent Sound From Speaker This could be due to poor battery connections. Ensure they are tight and the batteries are securely clipped into place. Radio transmission from passing taxi or vehicle using radio transmitter equipment. Loose speaker, in which case the speaker needs fastening back into place. The Detector Drifts Out of Tune Temperature drift caused by the change in air temperature when a machine is moved from a house or a car into the open.
