Put on your headphones turn on the detector, set the Noise Cancel and then set the Threshold to zero. Now raise the volume to max and retune the Threshold so it is just barely audible. I had you turn it to zero so in case it was too high, it wouldn't blow your ears off! Set it so it is buzzing enough to know it is there for the purpose of hearing a rejected target null out. But not so loud that it is distracting. Like I said, make it just barely audible. With the Noise cancel channel set, the volume at max and the threshold set correctly, now ground balance your detector. If you have questions on that, let us know. But after all these other things are done, turn the Sensitivity up as high as you can without making it false all the time when you sweep. If all the other settings are correct, you should be able to run a fairly high Sensitivity in areas that are not loaded with trash. I can usually run mine in the upper 20's at those type of sites. But in areas with a lot of trash, you'll want to lower it a bit to keep it from chattering when you sweep.
To pinpoint without using the Pinpoint mode, after hitting a target, simply wiggle your coil back and forth over it, while slowing dragging it toward your feet. At the moment the signal drops off, the target will be directly under the front tip of the coil.
