7.1Searching

The SD2100v2 is a ‘motion’ detector, which means that it must be moving in relation to a target in order to detect it. DO NOT set your shaft length too short. If the coil is too close to your body it may detect your pick, the battery, or any other metal that you may be carrying.

NOTE: DO NOT wear steel cap boots or shoes with metal eyelets when detecting.

If you find that you are getting false signals as you sweep the coil, check that they are not produced by any metal that you are carrying. Move the coil closer and further away from your body to determine if the signals are coming from items such as your pick or the battery. If the signals are from these items you must increase the distance between them and the coil.

The coil should be swept over the ground in a side-to-side motion. As the operator moves slowly forward, the search pattern resembles a snaking path. To ensure that the ground is thoroughly searched, it is advisable to approach the area from three directions as shown in Figure 6.

While sweeping the coil it is important to keep it parallel to and at a constant height from the ground at all times. The easiest way to achieve this is to have the coil lightly brushing the ground. Be aware of any tendency to raise the coil at the ends of each sweep as this will reduce the detection depth (see Figure 6).
