Keep in mind that these detectors can’t be completely submerged because their control box is designed to be out of the water. Many handheld models do not involve headphones at all because they are meant to alert you when finding something metal – either via a display or by vibrating. Make sure that you are looking at the right product before making your purchase. Some metal detectors come with headphones while others do not include them and require you to purchase them separately.
For our most recent round of testing, we spent three full work days digging around in the dirt, measuring, burying, testing and then digging again to find out how accurate these metal detectors are. Our experts have six years of experience testing metal detectors, so they know you want one that is accurate, lightweight and easy to use.
After all, a child searching for quarters on the beach has different needs than an adult treasure hunter in the field. The models on our shortlist offer various search parameters based on their intended audience. Valuable metals such as gold and silver have different electromagnetic properties than “junk” metals such as iron, tin, and aluminum. This allows the user to concentrate on more valuable metals that could be lurking underground, such as gold and silver. For example, the typical gold signal is noticeably different than the typical aluminum signal.
Pulse induction metal detectors are best suited for use in saltwater and for diving. You can even find an underground metal detector that has been custom made for the open sea. Depending on your level of experience in metal detecting, you might need to look for a device that is custom made to suit your specific level.
You can choose either a pulse induction (PI) or a very low frequency (VLF) detector. There are two different types of technology used in underwater metal detectors. The device is not 100%25 waterproof and can not work in the water. BEST GIFT IDEA: As a safe, easily operated and portable device, it is ideal for children who have fancy on treasure hunting. Daylight hours are the best time to metal detect underwater because you can see what you’re doing and its generally safer all round.
The inexpensive all sun Junior Metal Detector would likely appeal to parents who want to give their child the experience of metal detecting without spending a lot of money. A quality metal detector’s discriminator filters out common metal hits electronically, allowing only hits from possible gold or silver sources. A metal detector’s circular base contains two wire coils: a larger transmitter coil and a smaller receiver coil. Please see our product list, above, for our top recommendations in the metal detector field.
When the Teknetics product line was recently re-launched, MetalDetector.com was one of the first partners we contacted. I have to say that I was impressed with their operation and knowledge of the Teknetics product line. Their team of knowledgeable, helpful and friendly staff and family make their dealership a first choice for the treasure hunter. Garrett has a longstanding quality relationship with Detector Electronics Corp since the 1980s.
But as you’ll see from our reviews below, some PI models are better at discriminating between junk metals and iron, and precious metals. I first got into it after scuba diving metal detector running into an old friend on the beach who happened to be detecting (Mind he didn’t actually find anything whilst I was there), it certainly got me curious.
This change in magnetic polarity is what the receiver coil actually detects. Any metal object that receives this electromagnetic charge becomes “excited” at an atomic level. Most consumer-grade metal detectors use an older technology called VLF (very low frequency) detection. And please continue reading this shopping guide if you’d like to learn more about metal detectors. The tone lets the user know that some form of metal has been detected.
