[size=medium]ORX has three breaks. Can tell me what VDI numbers are at the breaks?
Thanks.[/size]
Therefore, in the two
DEFAULT Coin programs w/o changes, The XP
ORX had Two Tone Breaks to separate the Three Tone modes. A break between the Low and Mid Tones, and a break between the Mid and High Tones. That is when used in one of the 3-Tone Coin Modes w/o any changes to the settings.
With a change in the Iron Volume 'ON' and 'OFF' you can eliminate the Low Tone in the 'OFF' setting.
However, the design of the
ORX uses two words in the terminology that are either not correct, such as
"Iron Volume", or not used the same way the majority of metal detector models have been used, and that is
"Disc." or Discrimination. They also have eliminated one term for a separate control found on some models, and that is an adjustable
'Tone Break.' Instead,
and not mentioned as such in their User Manual, is the one variable 'Tone Break' adjustment. That is the
Low-to-Mid Tone-Break setting, often referred to as the Iron-to-Mid-Tone break-point that is incorporated in the variable Disc. adjustment.
The User Manual does provide a rough graph that shows approximately where the two Break Points are ... WHEN THE DETECTOR IS AT THE DEFAULT SETTING. That's on Page 06 of the
ORX User Manual. It does not give a specific numeric VDI reference number, just a rough graph and you can kind of 'estimate' where the Two Break Points are. As I eyeball that depiction, it suggests the Low Iron Tone would be
'about' '24,' and the Mid-Tone to High-Tone Break-Point would be
'about' '63' or '64. That is how I would generally line a reference number up which hasn't been quite correct t how I see and hear targets respond around that upper Tone Break.
Then come the problems. At turn-on, the two
ORX Coin Programs are working in a 3-Tone mode, and long as you make no setting changes and leave the Iron Audio turned 'On.'
But, if you change the default Disc. setting of '7' too much either direction, you might be working in either a 1-Tone or 2-Tone mode all based upon where you set the Discriminate level. There could be two different 1-Tone modes, or there could be a 2-Tone operation. Many makes and models of detectors are made a bit differently, and that's sometimes based on why or how an engineer decides to make a detector, and at times it is by request or instruction from someone else. Let me use one of my favorite models for serious Relic Hunting in some debris-contaminated sites, the Nokta FORS CoRe.. This model comes with a 2-Tone function [size=small]
(Breaking at the Ferrous / Non-Ferrous Break-Point)[/size] and a 3-Tone mode, so let's compare the
ORX and CoRe in 3-Tone.
The CoRe has two fixed or pre-set Tone Breaks to establish the 3 Audio Tone segments, and the first Tone Break is at the Ferrous and Non-Ferrous Break-Point. Therefore, all of the common ferrous targets will fall in the Low-Tone, or Iron Audio, numeric VDI range of 01 to 40.
With the Nokta CoRe, the 3-Tone mode is using preset, dedicated Tone ID Break Points. Those are internally 'fixed' in circuitry at a numeric VDI of '40', which is the Ferrous/Non-Ferrous break-point to determine the Low-Tone, or Iron Audio, and the Mid-Tone, then at about '80', which is the break-point between the Mid-Tone and High-Tone audio. Zinc Cents and Indian Head Cents have a comparable conductivity and numeric read-out at about 82 to produce a High-Tone. Separate from the pre-set Tone Breaks, the CoRe has a variable Discrimination that can be increased to reject or accept unwanted trash.
For example, a Disc. setting of '10' will just be
accepting most common Iron Nails and targets of greater conductivity. That includes more conductive ferrous trash.. An increased Disc. setting of '21' will then be
rejecting most common Iron Nails. You will, however, still be
accepting some Iron junk that is more conductive than a setting of '21,' and producing a low-tone Irion Audio from accepted targets that are still in the '21' to '40' Low-Tone Iron Audio range. At a Disc. setting of '40' virtually all common Iron Trash will be rejected, or Discriminated out, and you'll only hear targets that fall in the Mid-Tone and Hgh-Tone TID zones. To most folks that would be a more 'normal' Discrimination design that is separate from a Tone ID and Tone Break design.
That example, with the Nokta CoRe, uses a fixed, pre-set Tone-Break. A different design concept would be the Nokta Relic which, like the CoRe, has a separate variable Discrimination control to set the desired rejection point for unwanted trash. And it also has a variable Tone-Break control instead of an internally preset design, and that permits the operator to adjust desired Tone-Break settings between th4e Low-Tone and Mid-Tons as well as the Mid-Tone and High-Tones when using the 3-Tone mode. Thus, instead of being preset, like the CoRe, the user can adjust BOTH of the Tone-Break as desired separate from also adjusting the desired Disc. level.
Regardless of where the user adjusts the Disc. level of rejection, it is totally separate from the Tone-Break setting that was either preset [size=small]
(CoRe)[/size] or user-adjusted [size=small]
(Relic)[/size].

•[/size] Now, let's look at the XP
ORX and how it uses a different circuitry design for its 3-Tone operating circuitry ... [size=x-large]
•[/size]
[size=x-small]►[/size] As mentioned, the
Default Coin Fast and Coin Deep modes, at turn-on, do provide a 3-Tone search mode when unchanged.
[size=x-small]►[/size] If that Disc. Level setting is at the default '7' then most common Iron Nails will be rejected. If the Iron Tone is 'On' or 'Off' will determine if you hear the low ferrous tone or not here the low ferrous tone.
[size=x-small]►[/size]
ORX's Low Iron Tone or Low Ferrous Tone variable adjustment: This is the unmentioned part, at least in my User Manual that came with my
ORX supplied with the 5X9½ HF DD coil. That Tone-Break is incorporated as part of the Disc. Level. control, and regardless of where it is set from '01' to '99' ALL targets at or below that setting are in the Disc. Level range and also assigned to the Low-Ferrous Tone audio since it is a setting at or below the Disc. point.
• Therefore, if you have the Iron Tone turned 'ON' and adjust the Disc. level down to a setting of '00', there are NO Discriminated targets and ALL targets will produce the same High Tone audio response. A 1-Tone response based on the Disc. Level setting.
• If you have the Iron Tone turned 'ON' and adjust the Disc. level down to a setting of '00', there are NO Discriminated targets and ALL targets will produce the same High Tone audio response. A 1-Tone response based on the Disc. Level setting.
• If you have the Iron Tone turned 'ON' and adjust the Disc. level up to a setting of '62' then ALL
rejected targets below that setting will produce the Low, ferrous Iron Audio Tone. [size=small]
(Note, here I am referring to US Coins to include the common 5¢ 'nickel' and a Zinc or Copper 1¢ or 'clad' or silver 10¢ coin.)[/size]
With Iron Tone turned 'ON' you will hear 3-Tones and all
accepted targets at or above that Disc. setting of '62' produce a Mid-Tone, for the 5¢ Nickel coin, or a High-Tone audio response for the more conductive 1¢ and 10¢ coins that register in the 3rd or higher tone range. Yet
ALL targets below the Disc. level of '62' produce the Low Iron Ferrous Tone.
Turn the Iron Tone 'OFF' and it will then be a 2-Tone detector, beginning at the conductivity of the US 5¢ coin.
Increase the Disc. level to just accept the current Zinc 1¢ or Indian Head 1¢, and ALL targets at that conductivity or higher will respond with a single High-Tone, and all other targets with less conductivity will be rejected, producing a Low-Tone, Iron Audio, just like bits and pieces of ferrous trash. With Iron Tone 'ON' you get 2-Tone responses ... Low-Ferrous and High-Tone. There will be no Mid-Tone audio. Turn Iron Tone 'OFF' and it is then a 1-Tone detector with only a High-Tone.
Fortunately for me, I very seldom use a Disc. setting higher than just enough to reject common Iron Nails. For those who like to use a higher Disc. Level and try to deal with more problem trash targets, the XP
ORX can become rather confusing from an audio standpoint.
I hope that helps and didn't leave you with too much of a headache.
