Very low frequency (VLF): These detectors use a very low-frequency signal with electromagnetic fields to locate metal underground. In addition, the hidden cable is retractable, which makes it easy to extend the detector. BEST GIFT IDEA: As a safe, easily operated and portable device, it is ideal for children who have fancy on treasure hunting.
Superfast re-tune speed on a budget machine is almost unheard of, but Fisher’s cheaper model is rapid on the return. Another great option as one of the best rated metal detectors is the Fisher F22 with regard to value for money.
Larger portable metal detectors are used by archaeologists and treasure hunters to locate metallic items, such as jewelry, coins, bullets, and other various artifacts buried beneath the surface. Modern top models are fully computerized, using integrated circuit technology to allow the user to set sensitivity, discrimination, track speed, threshold volume, notch filters, etc., and hold these parameters in memory for future use. Shop metal detectors, digging tools, gold detectors, gold pans, sluice boxes, gold prospecting kits and more to find buried treasures. I hope this guide has helped you understand metal detectors, or at least inspired you to get out in the fresh air and find treasure.
3 tone audio identification can ping out audio tones set to differing metals, so set gold to high for example and listen for the high pitched tones. This gives you a better indication of what’s under the soil before you sweat it out digging down. The Teknetiks PRO has variable iron discrimination that you can adjust from 0-39, and FEtone which allows you to adjust the tones emitted from targets. Stopping every few feet to dig up iron is what makes or breaks this hobby, so it’s important to get yourself a detector that can discriminate well. Only the best entry-level useful link retune themselves quickly, which the Fisher F22 does with ease.
Bigger may be best because it cuts down on time spent searching an area, and it’ll find targets buried deeper in the soil, but the 5.75 inch coil is better for junk areas because it’ll have more focused discrimination. A Metal Detector that i can use to find everything on water and land. A smaller coil would see less of the ground, process less ground signals and allow you to increase your sensitivity to the point where you could be getting the same depth as you would with the larger coil in neutral ground.

The coil set-up is interesting because you can choose between an 8 inch or 5.75 inch. The Tesoro Compadre is one of the easiest metal detectors to use so if you’re a technophobe or buying for a kid this is a great choice.
If that’s the case then you should think about a 2-box style detector like the Fisher Gemini III. My best advice is to get the Fisher Gold Bug 2 for your small, shallow gold, and whichever of the Minelab PI machines your budget allows for the deep, larger nuggets.
Some metal detectors are designed to detect metallic objects or treasure chests that are hidden underneath such as chests of pirate gold coins. If the metal detector is to be used on salty water such as oceans, or if the whole metal detector will be fully submerged in water, then an underwater metal detector is the most appropriate.
The ACE 400 has a waterproof 8.5×11 DD PROformance search coil and weighs only 2.9 pounds. It lets you know if the metal falls within a certain group like gold, silver, or steel.
