Detecting Activities

Coinshooting

Coinshooting is searching for coins, usually in places like parks, schoolyards, church lawns, and people's yards. In most places where coins are likely to be found, there is also a lot of aluminum trash like pull-tabs and bottle caps, as well as steel bottle caps and often nails. Sometimes there is jewelry present. You will usually search using discrimination to get rid of the iron and the aluminum trash, even though this mode will cause you to miss some of the jewelry.

Much coinshooting is done in lawn areas, where digging holes would cause damage to the grass. We recommend use of an accessory hand-held pinpointer in such cases. Recovering targets is usually done by first accurately pinpointing the target, then carefully cutting a slit in the turf with a knife, and tamping it firmly when you are finished. In these situations, you cannot recover deep targets for fear of damaging the turf, so you can cut down on nuisance signals by reducing the sensitivity.

When searching on private property, first get the permission of the property owner. Most of the public places where one is likely to do coinshooting are city, county, or school district property. There is usually no ordinance prohibiting use of a metal detector as long as you are not causing damage.

Sometimes such ordinances do exist. Administrators and security personnel often have the legal authority to prohibit any activity they do not like even if there is no ordinance against it. If there is a metal detecting club in your area, someone will usually know what areas can and cannot be searched. If you are ever in doubt about hunting an area, then ask before hunting.

Be prepared to always put your best foot forward

when using a metal detector in a public place. Pick up any trash you recover; put it in a pouch or pocketed apron. This way you can explain that you are performing a public service by helping keep the place free of trash, especially pieces of metal or glass that could endanger a child at play. Be proficient at recovering targets without causing damage to the lawn. Explain that whenever you find jewelry which has personal identification marks, such as a class ring, you make an attempt to determine the owner and to return it. When someone who questions what you are doing understands that you are causing no damage and are actually performing a public service, you will usually be welcome.

Mechanicals (continued)

ARMREST

The armrest WIDTH and POSITION are both adjustable.

Armrest Width: The sides of the armrest can be bent inward and outward.

To best stabilize the detector to your arm and body movement, squeeze the sides of the armrest around your forearm. For a very secure fit, some users prefer to bend the armrest in tightly against the forearm such that you pry the sides loose each time you place your arm into the armrest.

Adjust the armrest in or out accordingly

Armrest Position on Pole: Remove the two bolts to position the armrest farther forward or back, to adapt to your arm’s length.

-- To reinsert the bolts, spin and twist them into place. Be careful not to damage the power cable that runs through the aluminum tube.

-- Insert both bolts completely through both sides of the bracket

before attaching the nut to the opposite side.

-- After reinserting the bolts, tighten them

Adjust the armrest forward or back, to adapt to your arm’s length.

very securely. You may need to use gloves for a firm grip. As you swing the detector from side-to-side, you want the bolts tight enough so that you do not feel any movement between the pole and armrest mounting bracket.

If you notice unwanted movement while swinging detector, check the tightness

of the locking collars. The locking collars must be rotated a full 270° to reach the locking position.

HEADPHONES (not included)

The F75 is equipped with a standard 1/4-inch stereo headphone jack at the rear of the unit, located under the elbow as you hold the detector for use. Any headphone with a stereo plug should work; headphones with a mono plug will not work. This device is to be used with interconnecting cables/headphones shorter than three meters.

Using headphones improves battery life, and prevents the sounds from annoying bystanders.

It also allows you to hear subtle changes in the sound more clearly, particularly if searching in a noisy location. For safety reasons, do not use headphones near traffic or where other dangers, like rattlesnakes, are present.
