<span style="background-color:#ffff00;">The most powerful method to use the Explorer in my opinion is with the Learn Accept/Reject and Edit functions in conjunction with setting.</span> I think of the detector in digital form and having 1024 notches. A notch is a set of digital numbers such as 3/28 for a copper coin. Using Learn we can set a window of rejection and acceptance that inclues a block of notches for a target. As an example we can set the notch window to include 4/28 3/28 2/28 and 4/27 3/27 2/27 so we have a rectangular clear area if the screen was set for all rejection to start with.
It is with the large, medium, and Small Square used in Learn that we instruct the Explorer as to what the window for accepting and rejecting targets is to be. We can reject a wide window and then accept a narrow one in combination if we desire. A wide rejection window would reject more tabs and compensate for a less accurate swings of the coil. The problem is we might hit a gold ring and reject it if it is close to the digital readings for tabs.
Assume a copper coin has a reading of 3/28 and a silver ring has a reading of 3/27. If we have a tight pattern of rejecting 3/28 and accepting 3/27 then with careful use of the coil we can kill the silver coin but detect the silver ring. If we have a loose pattern that kills 3/28 and 3/27 then we miss both the copper coin and silver ring with those digital readings.
A loose patter of rejection is easy to use in heavy trash for rejecting tabs but at the cost of rejecting more rings. A tight pattern will give more iffy hits that have to be centered by the coil, we dig a few more tabs, but we miss less gold rings. We cannot accept and reject the same digital reading such as 3/28 which is apparent.
Now here is something interesting to me in that can we play a tune with one note. When a target is hit and it has a digital reading of 3/28 then a specific tone is sounded. So can we tell a copper coin that reads 3/28 from trash that reads 3/28? We can if the beat is different just as a drummer can play a rhythm on a single drum. We need something to tell us that even if the note is the same the target is different. That is where sweeping the coil from different direction and also settings comes into play. Fortunately targets respond to sweeps from different directions and settings with more than just the same note. I am not saying this is always true but a great majority the targets I have tested in the field and at home can be properly separated between good and bad. When I work on a pattern all I want to hear is a difference between a tab and ring.
Null discrimination has always been to me the least liked method of discrimination. <STRONG>A tremendously powerful way to use the Explorer is to Learn Accept/Reject targets at the sites I search and then make some changes to other settings. </STRONG>I use iron, silver, copper, nickel, tabs, tab tails, the good targets I want to find and the common trash items to set the sound of targets. Threshold tone sets the lowest tone, limits sets the highest tone, and variability is how well we can tell the difference between the two. If we have the low tone and high limit set close together and variability set low then we may not be able to hear and difference between the low tone for iron and the high tone for silver. I use these setting for the clearest sound between iron and silver and also adjust them to compensate for hearing the other targets for accepting and rejecting.
One of the most valuable settings for me is to go to Audio1. Audio1, 2, 3 is adding digital filtering to the audio so that the sounds from co-located targets, I am using co-located to include all tagets under the coil at any point in time and not just something like a nail and quarter in the same hole, blend together. We might think this would be a problem and it may well be for a new user but is a blessing as we get more experience with the detector and sounds.
<span style="background-color:#ffff00;">A piece of iron will give a fairly consistent sound with Audio1 but sound wider than if we use normal audio.</span> However, a major change takes place if the iron is touching a silver coin. We can clearly hear the fluty or wavering sound of the iron and silver. I know that iron has a low tone and if the iron sound is fluty or wavers then I need to check it closer becaue it is co-located or have something different that I should check. A horseshoe will sound different if the shoe does or does not have any nails still in place. I found a nice old shoe from a site that makes it a great find becasue there was still a nail in the shoe.
<span style="background-color:#ffff00;">Here is something we can do to help us in this area. Use detect to switch between screens and the menu and the back button to switch between Ferrous and Conductive sounds. If the last menu action we accomplished was to select Ferrous after Conductive sounds then we can use the back button to go from Ferrous to Conductive sounds or if we desire or to go from Audio1 to Normal sounds to help in the identification of a target.</span> The Quattro has a switch to go from Ferrous to Conductive I think.
Ok, enough of this. I will see what corrections I need to make as the board reads this. Have a great Friday and weekend.
