DISCRIMINATION MODE (continued)
NUMBER OF TONES (# OF TONES)
This menu selection allows you to select the number of audio tones emitted by the detector.
Different search conditions, search objectives, or personal preference will determine how
many tones you want to hear. With the below settings, you can decide to hear the same
tone, regardless of the target category, or have different categories of targets induce
different tones.
The “# OF TONES” selections are:
1: Single Medium pitch tone.
All types of metal induce the same tone.
1F: Medium-to-High pitch tone varying in proportion to target signal strength.
Large shallow objects will produce a squeal. The variable audio pitch provides you more
information about the detected object, but some people find the sound on strong signals too
annoying.
2F: Two tones.
Similar to 1F, except that iron produces a low-pitched tone regardless signal strength.
Useful if you want to hear all targets and want to identify iron. Most relic hunters prefer
this selection.
3H: same as 3, except that nickels produce a high tone.
3: Three different audio tones. Iron produces a low pitch tone. Aluminum trash, zinc
pennies, and nickels produce a medium tone. High conductivity coins produce a high tone.
The 3-tone selection is often preferred for coinshooting. Most users will set the
discrimination level below nickels, at about 25, and dig only objects that produce a
consistent and repeatable high tone. NOTE: with this setting, steel bottle caps may produce
consistent high tones, similar to coins. See Capabilities & Limitations section for advice on
identifying steel bottle caps.
4H: same as 4, except that nickels produce a high tone.
Useful when coinshooting in a trashy area.
4: Four different audio tones This selection is similar to 3, but with a fourth medium-high
tone for targets in the numeric range of 53 to 65. This four-tone system is useful for
searching in areas where there may be very old coins which register in this range.
dP: Delta Pitch This setting produces a tone whose pitch varies in relation to the visual ID
number -- the higher the ID, the higher the pitch. Good for relic hunting. This setting is also
useful in areas with a high concentration of steel bottle caps. Coins will produce a fairly
constant pitch as you sweep back and forth. Bottle caps produce inconsistent tones, often
with a squawk at the beginning of the sound.
