Audio1

[Anonymous]

I have been intrigued by the sounds, Normal, Audio1, 2, and 3 and how they work in conjunction with FAST Recovery. Minelab indicates that Audio1 is best for good discrimination in areas where there is trash co-located with good targets. This sounds odd when you first read this when you think of the FAST setting but is in fact correct. Audio1 will give a wavering tone and one can hear the high-low waver. I wondered how FAST, which seem to be counter productive to this idea helped so checked this out today. Audio1 give a wavering sound on co-located targets and when FAST is turned on the wavering sound is more obvious. It is not as continuous as with FAST OFF and Audio1 ON. I have always liked Auido1 as I have noticed that the discrimination accuracy is better as far as I can tell. This is also true to some extent with other filters I have used. The bottom line is FAST does help the Audio1 to give a more pronounced wavering and makes it a little easier to discern the high low wavering sound. I think I said before I prefer Audio1 as you don

Cody,
My Exp II makes the thud you mention without Audio 1 on. It happens when the coil has just finished passing over the target and I hear the Thud. This happens on air tests and buried targets. It happens in factory preset with gain set from preset and up. More pronounced with higher gain settings.
Are these normal sounds to the EXP II

Yes it is normal but is more noticeable at Audio1, 2, or 3. It sounds to me like the audio being cutoff depending on the setting partly due to digital filtering. It sounds like you chop the end off the sound and there is a thud as the knife hits table. Where the functions are set will have a lot of do with how much of this we hear and what headphones we use as to how clear.
