I have had this machine for a while now and have today finally discovered the secret to this machine....Although I have had this machine for a while I have always used it in quiet mode that is with the threshold right down on zero...and it still was a tad better than my whites GMT on sensitivity...the whites gmt when you increase threshold you lose sensitivity...But on the garrett when you increase the threshold to 10 or even maximum it becomes a real powerful VLF and it is extremely sensitive to small metals with fairly smooth threshold and when the VCO is turned on Auto GB and Auto threshold all turned on it becomes an absolutely Gem to use ...
The air test I have done are as follows..
.
5cents austrlian coin at 22cm max
20cents australian coin at 32cm max(20cm without any threshold)
1 dollar australian coin at 32cm max
and the small stainless washer weighing at 1/4 gram at 15 cm (awsome)

So If you dont mind operating with the threshold tone and vco on (something alot of users of this machine dont know or use)....you will gain 10cm of sensitivity....So on small gold it should be magnificent and beats the gmt easily and up there with the best of the VLF machines ....
I hope this helps somebody

threshold noise is best....

If you speak to technicians with the metal detector manufactures, you will discover that "silent search" is a sales pitch thing, and not better for depth. It as created as an sales option pitch, to sell metal detectors. The technicians told me, to have a good loud audible hum, in the earphones, and you will hear the smaller, deeper, targets better. Silent search has a harder time hearing small deeper older targets.

And keep sensitivy turned up as high as it will run in a machine, as long as the ground is not so overly enladen with minerals, and you will go deeper.

If you cannot hear it, you will go over it, and not find it..... That is why I like to over ride audio controls... I have a unit that takes loud signals, brings them down, and takes faint signals, and amplifys them, as I am older and hard of hearing. If I did not do that, I would not find the older deeper small jewelry and coins.
