Or a more accurate subject line should be sweeping the coil. As said in my previous post I would make another to try and explain the way to get the best audio results from the explorer. I have been getting quite a few emails and replys or reading from people saying they cant get the steady tones they hear on my explorer sounds page. first of all let me say I mainly use normal audio with fast recovery, so I really cant say that any of the other audio options will get the same results. The absolute most important factor in getting a solid steady tone is the amount of left and right motion over the target, it should be as little as possible. the Explorer is very sensitive at the coil edges as most of you know and getting the target wiythin a few inches of the outside will cause warbling or unsteady readings. Another very important thing is keeping the coil as flat and close to the ground at all times as possible through out the entire motion of your swing, this is why I prefer to call it sweeping
During the sweep of the ground you hear a response, whether warbly a good tone or blip. stop and get the coil right over the area you heard it slowly narrowing down the amount of side to side motion. till you are just hovering the coil directly over the spot to get best response. all it requires is a small amount of motion to see the target. no more than a half inch of movement to each side of the target. As you narrow it down speed up the wiggle and you will get the best response(especially true for deep targets) then slowly work your way around the target without ever stopping the wiggle, kind of pivot your turn as if the target was an anchor to your coil, if the reading remains the same tone and if you can get a response in more than 2 directions with the same tone and steadiness its usually a good one. there are exceptions depending on how close junk targets may be, but usually from at least two of the angles you will get a good tone. Try practicing at home in the yard with a few targets, dime, nickel, round tab, shotgun shell etc by placing the targets on the ground a foot or so apart and wiglling the coil quickly over the target at the same time keeping the coil parallel to the ground and a few inches off the target at all times, any lifting of the coil may cause an off tone.. you will see that the good targets respond almost the same steady tone from all directions in the circle ,while the junk will almost always change tone completely from another direction, if you do it with the circling of the target you hear it immediately. It is almost always true for odd shaped junk targets like round tabs and shotgun shells on their side. if the junk is fairly symetrical it may not happen as often(like a shotgun shell with bottom side perfectly upright), but luckily most junk is not perfectly round or square. At the same time a non symetrical target of good metal is usually a pretty constant tone, it may seem to get louder or seem bigger in one direction but generally the tone frequency remains the same.. there are always exceptions but for the most part I find this to be true. I have a hard time trying to put to words what I describe as the wiggling of the coil over the target, but if you picture yourself erasing a three leter word off a piece of paper quickly, the moyion of the wrist while moving the head of that eraser on the paper would be similar to the motion of the wrist moving the coil over the target. Lots of times when you get falsing while sweeping, using this motion will tell you right away there is something good or not good there and you can continue on your way. many times a deep target will get that same sound and then volume and signal will get better over that target during the circling of the target. Everything comes with time and training your ear to those good tones takes more than my attempt at an explaination on a post here, but it will come to you. The more you hunt the faster it all sinks in so the real secret is getting out there and using it <IMG SRC="/forums/images/smile.gif" BORDER=0 ALT="
"> Slow during the search sweep, quicker small sweeping over the target, and keep moving around the target without stopping that motion. After you get this down you can almost call a target from the initial hit, and one other thing to remember is that on surface targets less than 3 inches you may need to lift the coil off the target to get the good response without warbling tones.
