newbie threshold vs volume adjustment question

[hotrod53]

I'm still trying to adapt to the sounds of my 705 gold. If I increase the volume, obviously it will make everything louder, but will it accentuate the difference between a good and a junk target? Maybe I'm just not loud enough to hear the differences? I'm looking at the examples in the manual and it appears that increasing threshold will miss small or deep targets, but they say "when threshold and volume are used together, there is a greater control over target audio response".

I set up my background noise to be as it was described to me as "like a gnat", my threshold is at 1 if I recall, maybe I need to increase my volume? My brother keeps telling me that he can hear the difference as he searches, but he isn't using headphones. I understand what he means because that is how I was with my other detector, I'm just not hearing it with this machine. I'm using phones with mine since that's how I'm used to detecting.

Recognizing that Volume and Threshold each have separate settings for use with and without headphones, my suggestion would be to plug in your headphones and set your detector's volume to max. Then set your Threshold so it just barely audible. Set a target to reject and see if you can hear the Threshold blank out as you pass the coil over that target. If you can hear the Threshold go away, it is probably OK. Then scan a target with a conductive value in the accepted range and see if it is too loud. If you need to lower the volume at this point, use the volume controls on your headphones. Try running with minimal discrimination to better hear the pitch variations of the different notch segments. The more ferrous the target, the lower the pitch. The primary difference between "good" and "bad" targets will be the pitch of the audio response, not the volume. JMHO HH Randy

I did as you suggested and it made a marked difference. I now have a slight buzz in my ear and I can start to recognize targets better. I'm still struggling somewhat and I think that it's because of the places that I have hunted. I did some park hunting yesterday as well as an old Church site that I had hunted literally 20 times before with my last detector. I didn't find a dog-gone thing but it was still swing time practice. I need more good targets to get used to the tones. Finding this crap is a waste of my time, yet I now know well what crap sounds like...LOL
