AhNibblet Posted May 12, 2023 Share Posted May 12, 2023 First off I have watched several youtube explanations of threshold. I think as a noob, I am missing something. I just don’t really see the usefulness of more tones to listen to and process. Am I right in understanding a break in threshold is the same as an iron grunt? Can someone who uses threshold explain the benefit? Link to comment Share on other sites More sharing options...
Steve Herschbach Posted May 12, 2023 Share Posted May 12, 2023 A break in a threshold is just a break in a threshold. It can happen for numerous reasons, ferrous, non-ferrous, EMI, ground mineral…. all it really means is possibly something to investigate depending on the detector and the exact circumstances. 4 Link to comment Share on other sites More sharing options...
Jeff McClendon Posted May 12, 2023 Share Posted May 12, 2023 The latest detectors have reference and live thresholds. Reference thresholds will go silent over a target with a target ID that is being discriminated out or rejected. For people that don't want to hear for example, a lot of iron grunt audio, rejecting the iron target IDs and turning up the reference threshold volume level will help to alert them to ferrous or mixed ferrous/non ferrous targets without a lot of audio racket. Live thresholds can boost actual target signal intensity and audio volume especially on borderline targets that are close to giving really weak audio responses. 5 Link to comment Share on other sites More sharing options...

Second off>> Not all thresholds are created equal. Not many machines work like a Sovereign GT. It will take some experimentation regardless of the machine!

No muchas máquinas funcionan como un Sovereign GT. ¡Tomará algo de experimentación independientemente de la máquina! Eleanor !!!. My unicorn, I've been looking for this machine for a long time. I recently slipped that one in eBay Germany. And that the title was misspelled... Brand new, it had two hunts, aggghhhh... There is great demand for the Sovereign GT. Logical...

AhNibblet Posted May 12, 2023 Author Share Posted May 12, 2023 Are live thresholds the same as the Manticore’s true thresholds for the prospecting audio theme? (This topic can get complicated with machine differences and company terminology.) Link to comment Share on other sites More sharing options...
fogrider Posted May 12, 2023 Share Posted May 12, 2023 I prefer to set my threshold to a barely audible level. Just a light hum. Link to comment Share on other sites More sharing options...
Steve Herschbach Posted May 12, 2023 Share Posted May 12, 2023 On some new models, including the Manticore, you have a reference threshold. If you notch items out instead of using full tones, the threshold can go silent or “null” when passing over these rejected items. It tells you that you went over a rejected item, which could be a pull tab just as much as being a ferrous item. Just depends on the notch settings. If you note lots of nulling, it can indicate thick targets and therefore possible masking issues. Again I’ll say, it’s very model specific what a threshold break means. But what I’ve described is common on new models with reference thresholds employing rejection rather than tones for target selection. I generally use full tones so for me it’s a non-issue. 2 Link to comment Share on other sites More sharing options...
