Here's a technique I use. As I said, I point the scan gun at the ground and walk in an arc in front of the transmitter antenna about 13.5 feet away (radius). Now when I get directly in front of the antenna the tone and clicking will be the loudest, so I look for any variance. In other words, if the tone starts to decrease instead of the usual increase I check it out. So when I am pointing the scan gun at the ground the handle is in the horizontal position. I twist it back and forth like turning a key in a lock. I watch the meter and normally when there is a tone the meter will stay up high, or no tone the meter stays low, but right near the signal line the meter will deflect almost the full scale with each twist of the scan gun back and forth. I don't know how well this will work with the VR2000 because the receiver antenna is quite a bit larger and not too easy to twist quickly. I don't twist it all that much, probably less than forty-five degrees each direction (towards the transmitter and towards the target area).
