How to Learn to Use a Metal Detector
Beach combing and treasure hunting have been aided by the use of metal detectors for many years. The use of a metal detector to assist in finding metal objects is a technique that many treasure hunting enthusiasts prefer. These devices are also highly efficient at finding any small metal objects, including bottle caps, metal cans and powerful models can even detect underground pipes. All models of metal detectors are somewhat different, but utilize the same principal of a magnetic base coil for the detection of metals. Learning how to properly use you particular model of metal detector will greatly enhance your treasure hunting pursuits.

1
Read your metal detectors instruction manual before trying to use it to search for objects. All models will vary slightly in use, but employ the same basic principals. This will instruct you on how to apply filters, and change settings to fine tune your detector.

Place your metal detector on a wooden table, then gather an assortment of items, each with different metal properties and place them in a row on the table. Good items to use are: Bottle cap, coin, metal can, can pull-tab, nails or screws, gold ring, silver ring and a penny.

Turn the detector on and pass each item underneath the base coil. You will hear a specific tone for each individual item as you pass it under the coil. Note the sounds, so that you can remember which tone represents which item.

Use the tone filter feature to filter out sounds for objects that you're not looking for. If you're only searching for gold or silver, filter out any other tone for other metals that you don't want the detector to pick up. Also, apply the ground balance filter if this feature is available to you. This feature filters out smaller metallic mineral particles particularly present in sand.

Use slow steady sweeps as you pass the detector coil over the ground. This should be done in a side to side motion, as you walk, with the base coil parallel to the ground for the greatest efficiency.

Tips & Warnings
Don't forget a small shovel to bring with you along the way. A collapsable E-tool (entrenchment tool) available at many sporting goods or army surplus stores is ideal to carry along.
You should not use a metal detector if you have a pacemaker, though some models clam its safe.
