CAPABILITIES AND LIMITATIONS

DEPTH

The Time Ranger™ can detect U.S. coins to a depth of about 9-11

inches under good conditions. Large objects (55 gallon drums,

manhole covers, etc.) can be detected to a depth of several feet.

Electrical interference from power lines and from electrical

appliances and electronic equipment can reduce detection depth, or

cause audible interference making it necessary for the user to

reduce the sensitivity setting. Soils with large amounts of iron or

salt minerals, may also reduce detection depth or necessitate a

reduction in the sensitivity setting.

TARGET IDENTIFICATION

The Time Ranger™ identifies the probable type of metal object

("target") by measuring its “effective electrical conductivity”, which is

displayed as a number from 1 to 299 on the LCD screen. The

"effective electrical conductivity" of an object depends on its metallic

composition, size, shape, and orientation relative to the searchcoil.

Since coins are minted to tightly controlled specifications, they can

be identified with good accuracy. Identification of pulltabs and foil

is less consistent because these kinds of targets come in wide

variety. In general, smaller objects, and objects made from lower

conductivity alloys such as iron, bronze, brass, lead, pewter, zinc,

etc. will read lower on the effective conductivity scale. Larger

objects and objects made from higher conductivity alloys such as

silver, copper, and aluminum, will tend to read higher. The notable

exceptions are gold, which usually reads low because it's rarely

found in large pieces; and zinc pennies, which read moderately high

because of their size and shape. Although nails and other iron and

steel objects will usually read as iron ring-shaped pieces of iron (for

instance steel washers and harness rings) will usually give medium

to high readings. Flat pieces of iron or steel, such as can lids, will

occasionally do the same.

Most targets can be identified correctly in air out to about 7-10

inches. The minerals in many soils will cause identification to be

less accurate. However in most soils effective target identification

can be had to a depth of at least 4 to 6 inches.
