| If you attempt to begin detecting while you are inside your home, |
| |
| you will quickly find that there are many metallic objects (such as |
| |
| nails or reinforcing in the floor) which will result in almost |
| |
INCORRECT | continuous detection. There will also be interference from TV sets |
| |
|
| ||
| and other household appliances. Placing the sensitive detector coil |
| |
| near large metallic objects can result in temporary saturation of the |
| |
| sensor, meaning that it then cannot detect small objects. Therefore |
| |
| it is best to turn your detector off and head outside, as far away as |
| |
you can from sources of electromagnetic disturbance. |

| Sweeping the coil |
| |
| The Explorer II will perform at its best when the coil is kept in close |
| |
| proximity to the ground. This will increase detection depth and |

| coil is very important, as variation in coil height at the end of each | ||
| swing can cause confusing sounds and reduce detection depth. | QUICKSTART | |
