(P32) Pinpoint
One of the most valuable aids to pinpointing is measuring the size of a target. The pinpointing mode has an automatic shrinking circuit to help with pinpointing. However, there is no problem measuring the size of a target as the automatic shrinking circuit operates slow enough to give the user good target size measurement. When pinpointing the crawling around in the soil that some targets seem to have is an example of the shrinking circuits working. This will be noticed by thinking the target is a good foot from where it actually is. When we sweep the coil it appears to be in one place and then in another and then move to different location and then we finally get it centered.
When we are coin and jewelry hunting the size of the target is important. If we put a coin on the ground and sweep the coil over the target we will notice the response is much narrower for a coin, ring, etc, than for iron. This has been true since the first VLF I used back I in the seventies. Iron will have a wide response and precious metal a narrow one in comparison. It is fairly easy to use target size in pinpoint in conjunction with sweeping from different direction, digital reading, etc, to pass up most junk. A target can also be too small. I have dug a lot of very strong sounding targets that were incredible narrow only to find a BB or 22 slug or tiny piece of aluminum or other metal. If we use this in conjunction with depth it is also easy to pass up these as junk hits.
