I’v e been looking around for some really solid advice to put into a post and what seems to come to mind is to recognize that a detector does not “punch down” through the ground to detect metal.\u00a0 What it does is to separate ground and interference from metal.\u00a0 When you do a lot of pulse hunting it becomes clear that no machine is invincible–all detectors lose depth under certain conditions.\u00a0 Point being don’t expect too much from any VLF.\u00a0 A good demo is to run a VLF near a known source of interference–like a furnace or TV.\u00a0 Notice how when you increase the Sensitivity–target signals don’t disappear–they get “flatter” –that is–they go into the background and become harder to acquire.\u00a0 This is what happens in the field.\u00a0 What will get you more targets is to work with a moderate Sensitivity level and a slower sweep speed.\u00a0 This is what will allow you to go into “prime ” ground behind other hunters and make finds.\u00a0 With a VLF–try basing your settings on how the unit stabilizes in all metal mode–this is very telling–where you have “lilting” sounds or “nulls”–this performance loss will be even more pronounced in Discriminate–whether you can hear it or not.\u00a0 With these multi frequency machines–there is such a bias towards stability that they are capable of loosing depth but still having a smooth threshold.\u00a0 With a pulse you hear these threshold changes.\u00a0 A pulse teaches the tuning and coil control needed to get performance from any detector.\u00a0 Pulse hunting teaches you the reality of interference–and just how much of an effect it has.\u00a0 The more sophisticated many of these detectors get–the less aware we are of just what we are missing.\u00a0 \u00a0Unfortunately–there’s no such thing as an “idiotproof” detector–conditions always dictate.\u00a0 \u00a0If any of you VLF hunters have the chance to borrow a pulse–try it–a real eye opener.\u00a0 Another thing that’s worked well for me with VLF machines is not to be afraid to put in a reject block around “zero.”\u00a0 This will reduce the interference from targets in the ground that fall on both sides of “zero”–making for cleaner assignment of responses.\u00a0 The Sensitivity you run will be more usable–and you can set it higher with out so much of the kinds of problems described above.\u00a0 It will reduce “cross-feeds” making for more stable performance.<\/p>\n
