They look like the real thing, but DO NOT WORK like the real thing. BEWARE OF THESE CHEAP IMITATIONS. WE are the largest USA retailers of this product, we are factory trained and AUTHORIZED. The model 20 is a mid range directional locator, designed to be an all purpose instrument. It has the ability to locate gold and silver in both the natural state for prospecting purposes, or in the man made state like caches, jewelry and coin and so on. By using choice of a plug in accessory called the S 1 or S 2, the operator can set the 20 to magnify the signal from large targets, thereby IGNORING small targets and CONCENTRATE ONLY on cache size targets, or large accumulations of natural gold deposits. Long range locators are normally used alongside conventional metal detectors. The locators can quickly scan a wide area and determine if a concentration of gold or other valuables are within the reach area of the instrument. If no target is picked up, the operator can eliminate and just ignore the site, and move on to the next position to be scanned. If a target lock is achieve, then the conventional metal detector can be used to quickly search the designated spot in order to pinpoint and recover the target. A target lock is achieved when the MODEL 20, which is free floating on its handle, points to a particular area resisting from pointing away from it even when the operator swings past it. Easiest way to mentally picture a target lock is this : if you hold a campass in your hand, the needle will point NORTH. If you change the position of the compass, regardless of how you rotate it, the needle will resist the change, and still point to the original North position. The 20 reacts basically the same way. In order to minimize the target area, the operator can take several readings from various positions, taking note of where the visual lines from each position intersect. That will be the general area of target position. Now the operator needs to pinpoint the target center by searching a small area. The 20 is mostly designed to find somewhat large targets, but numerous EXPERIENCED operators are able to locate small targets as well. The SYSTEM 20 is not a comventional metal detector and does not work as one. If you never used long range equipment, you will need to spend some time learning what the instrument is trying to tell you before you become proficient with it. If you are not the patient type willing to spend time in the field with it and expect this to be your personal “magic wand”, then this is not for you. Distance and depth of the instrument is largely dependent on size of targets and lenght of time in the ground. Freshly buried targets or “test targets” setting above the ground will not generate strong pulls or target locks. Occasionally we will make an exception to this, if a valid reason is stated, but only if the item is unopened. Metal Detector Distributors 9203 Flatlands Ave Brooklyn NY 11236.
