That’s because you need to remove some sensitivity from your detector. So many aspects affect how deeply a detector can sense metal that it’s impossible to give a straight answer. Low-frequency machines at 2-4 kHz are best for deep-seeking everything, mid frequency 5-12 kHz for relics, jewelry and coins, and higher frequencies for gold. High-frequency kHz has shorter wavelengths and finds smaller targets with less conductivity, such as nuggets and flakes of gold. It’s your job to drop tin foil, nails, coins and gold in your yard and play with discrimination.
Using maximum sensitivity means ALL metal signals will ring out, including minerals and trash. An elliptical coil works in just the same way, albeit covers less ground in one swing, but it can reach into small, awkward spaces. They’re best for deeply buried objects and cover a greater ground surface, but they are heavier which makes a big difference for long sessions and water work.
US Patent 4,709,213: Metal detector having digital signal processing by Robert J. Beginner’s Guide To Metal Detecting by Julian Evan-Hart and Dave Stuckey. Code of Practice for Responsible Metal Detecting: Although written for the UK, the sensible guidance here will apply more generally in other countries, but be sure to find out about laws or regulations that apply specifically to your area.
The Bounty Hunter has three search modes – all metal, tone discrimination and full discrimination. I am looking for Gold flakes/small nuggets in a very mineralized iron ore area and quartz veins also to search in shallow streams. When considering your first machine, pay hop over to this site close attention to how much it weighs, especially if you plan on hunting for several hours at a time. If you’re hunting small, tight areas like playgrounds or very rocky areas like in gold country, then you should consider a smaller coil for better maneuverability.
This top of the line metal detector is in good condition, tested, works great. You can leave your coil on the detector with the ample storage room for easy transport. The unique design of the Minelab Excalibur II allows you to use it as effectively in or out of the water – this amphibious machine can move seamlessly from land, beach and wet sand conditions to underwater depths of up to 200ft (66m). Garrett AT Pro Metal Detector with MS-2 Headphones and Pro-Pointer AT, USA Ver.
If you have elbow or shoulder problems or another ailment that limits physical activity, it’s recommended to get a lighter detector. Some metal detectors are light as a feather while others are built like bricks and can be quite heavy. For those who like the best of both worlds, that may be a detector worth looking into. Alternatively, if you’re looking to cover large, open areas like beaches and farm fields, a larger coil might be a better option. The only real advantage it has over the DD (in my opinion) is that it can be easier to pinpoint your target.
Our focus will be on consumer metal detectors, but most of the information also applies to mounted detection systems, like the ones used in airports, as well as handheld security scanners. However, they may travel on many occasions to the beach or undertake some nugget hunting.
Some are easy to handle and can be used by everyone and others have more features and buttons thus suitable for advanced users. For the beginner with higher budgets and willing to spend more to get the best detector, the following options are available. Although they are sold for low prices, they are still effective in finding silver, coins and gold. There are others that combine nugget and relic hunting such as Whites MXT Tracker which goes for $800 and the Tesoro Lobo SuperTRAQ which retails at $700.
