Is it me or is the Fe Co numbers off on the emulator... the sounds don't sound as high as I've seen in videos for dimes and quarters... :huh: my Fe's haven't got past 4 on that and Im always seeing like 12- 46 and such on a real detector.
Hi folks,
I checked the Emulator and found that the tones did sound a bit low. I checked Variability and Limits (Audio -> Tone ID) and found that they were not set to maximum. The definitions for both are:
Tone ID Variability
Range: 1–30
Factory Preset: 25
Variability controls how much the audio pitch will change depending on target characteristics. A high Variability setting results in a maximum variation of pitch from target to target. A high Variability can aid in identifying targets in close proximity to one another, and is recommended when using a complex Discrimination Pattern.
A low Variability setting results in a minimum variation of pitch from target to target. With a low Variability, target information is compromised, but the target response will be more consistent. This is recommended for users new to multi tone detectors, or if you are using an ‘All Metal’ Discrimination Pattern.
Note: Even though you may still adjust the Variability when the No. of Tones is set to 1, it will not have any effect on the target audio response.

Tone ID Limits
Range: 1–30
Factory Preset: 30
Limit allows you to adjust the maximum audio pitch of all tones emitted for Tone ID Sounds; Ferrous and Conduct. Limits is only available if the Number of Tones is set to Multi. A high Limit setting will allow E-Trac to produce very high pitched target signals as well as low pitched.
Minelab recommends setting the Limit control to the highest tone you are comfortable with. Use a highly conductive object, such as a large silver coin, to test your Limits setting.

After I set both to 30 the dimes and quarters sounded like they should (higher pitch). I used my US Coins target file to test this.
A lot of the big silver is in the low FE range, but the smaller silver and pennies fall on or near the FE12 line, a least for the coins I tested.
This is a slightly padded pattern made from the US_Coins data.
HH!
