One of the most commonly asked questions I purchase when they talk treasure hunting is, “What’s the best metal detector?” Everybody asked that question is gonna have his/her own slant about them. Each has their unique experiences, with each having their very own “type” of treasure they are going for. I’m no exception. So, I’m going to give my “slant” and find out if a few things i contribute will narrow the choice down a lttle bit.

First… through far the main criteria in selecting a metal detector is “choose a metallic detector that you’ll use.” I would not care how fancy or expensive a metallic detector is… if all it can is sit inside a corner having a jacket hanging regarding this, it’ll find forget about treasure when compared to a child’s toy. I have faith that this, when i have witnessed individuals with a collection of metal detectors… some fundamental, and a few fancy… and many times they opt for the basic detector, because every one of the settings, controls, buttons, and what-nots on the fancy detector are just too complicated for the children. They just don’t appreciate it; they don’t really understand it, and therefore they just don’t apply it. So, in case you are not used to metal detecting, or don’t relish the thought of being forced to determine what dozens of buttons, knobs, and screens do and mean, then perhaps you’re better off which has a more “basic” model, at least until you get experience and find out what exactly you would like and will handle.

Metal detectors just do that. They detect metal… all metal. Ferrous metal is iron based and could be interested in a magnet (iron, steel, etc.). Non-ferrous metal is just not iron based and does not be drawn to a magnet (aluminum, copper, nickel, silver, gold, platinum, etc.).

Ground Balancing – Many detectors will offer circuitry to deal with mineralization inside the soil. Mineralization may be a result of salts, iron, “black sands,” “hot rocks” or another “hot” deposits that naturally occur. If you intend on nugget-shooting (detecting for gold nuggets), choose a machine that is certainly created specifically for nugget-shooting. If you are likely to be beach combing (detecting at the lake), pick a beach machine (not only will be the circuitry better built to handle the mineralization purchased at the beach, most are better created to withstand the saltier environment). Should you be detecting at various locations, such as parks, fairgrounds, and other public places, a “general purpose” machine will perform. Keep in mind, you’ll need a machine with some form of ground balancing capability.

Sensitivity – Most detectors have a sensitivity adjustment. The search coil of the detector is essentially an antenna which has an electromagnetic field emanating in the pattern that is certainly “shaped” from the model of the coil (round or elliptical will be the most common). The space (depth) it reaches is a factor of output and frequency. If this field is disturbed by the target (metal), the circuitry senses the disturbance and also the detector registers with sound and/or visually on the display (meter or graph). The sensitivity adjustment enables the detector to sense this disturbance by smaller targets (in a given depth) or perhaps a given target at the greater depth. The trade-off is the greater the sensitivity, the better the aftereffect of non-target “junk” and mineralization. Setting the sensitivity too high will result in false hits, approximately much electrical chaos that targets are missed, especially weak targets. Too much sensitivity can also result in a medium or large size target to “overwhelm” the circuit and make it blast an overload signal.
