Super tuning the High Gain/Low Noise

[Hombre]

Hi Guys and Gals

I read/ and see where alot of people are using the threshold knob turned close to maximum to get added depth, as with all adjustments, there is a time and place for such adjustments. On the older ED-120 Tesoros like the original Bandido, after making the initial ground balance with a normal 'just audible' threshold setting to get a good ground balance. Then, the operator could see a little better depth of detection by cranking up the threshold. This old trick was used by the old-timers to perk up the modulated audio of these early Tesoros on deep targets. As an example...say you are just puttering around with your 'ol Bandido (set in normal threshold) in and old yard and you get a sweet, small, faint deep sounding signal, then a noisey truck with a bad ignition drives by and screws up the ambient noise in the vicinity of where you are detecting. Then by turning up the threshold setting, it will pull out a better more 'saturated' audio signal in Motion Disc. Mode, with one caveant, if you switch to the Normal All-Metal mode without turning the threshold back to the normal setting, the saturated threshold audio with your headphones on,,, WILL BLOW your eardrums out........it's loud. The same thing happens for the High Gain/Low Noise

Thanks Randy........a good reminder for those just starting out witha Tesoro. Many of us from the old school learned those lessons the hard way......................

Same with the Deleon I guess. I was wondering why all those nails were coming up as 95's??? I was worried I might be missing out on little earrings and tiny gold.
