But remember, if you are an amateur, buy a beginner metal detector first and upgrade as you learn the art. These are among the few accessories that you are required to have when going for underwater metal detecting.
Hunting treasure on the beach is tricky because of the minerals in sea water. Detecting gold requires a level of sensitivity that isn’t needed for finding coins made of base metal.
Some of the examples of the best waterproof metal detectors include, Fisher CZ21 and Garrett Infinium LS which work well over 200 ft deep while others work at much lower depths. An electric current is sent from the control https://metaldetectorshub.com/metal-detectors/ box, through the wire all the way to the coil. The control box may have a digital interface or just knobs and may be waterproof or not. It is also where the wire from the control box is spiraled, all the way to the coil.
Start with an easy-to-use model that does a lot for you and move up as you get the hang of it. Once you’ve found a location with wide sweeps, you can switch on the pinpoint mode and hone in using the readings on the LCD screen. This aligns the response point to the center of the coil so you can determine the exact location of the item. It can penetrate well to a depth of about a foot, but its range is more limited. Garrett models use very low frequency (VLF) and pulse induction (PI).
For all purpose coin and jewelry hunting, stick to a single frequency VLF detector when first starting out. These are built more for salt water hunting and gold prospecting. This may be the biggest factor of them all, especially when you’ve never tried a metal detector. The 52-year-old Pompano Beach house painter and paper hanger has found at least $40,000 worth of scrap gold since he moved here in 1989, he says.
Higher frequencies are most commonly used for gold or detecting smaller items. This affects the depth and size of object the machine can detect. It’s always best to run the highest sensitivity if you can, as this provides the greatest depth. Automatic – Modern metal detectors can often determine the mineralization of the soil automatically and adjust the ground balance without user input. Preset – The machine has one (or more) ground balance setting that is preset by the manufacturer.

It offers three levels of sensitivity and lets you quickly narrow down the detection field when needed. However, it also has enough features to satisfy more experienced treasure hunters after they have mastered the basics.
Your Youtube homepage is littered with ‘Recently Watched’ videos of every type of detector review and unboxing. You’ve searched high and low on all the detecting forums, and read countless opinions, reviews and case studies – most of them likely biased.
There are two levels to this when it comes to products that can go underwater with the traditional looking metal detectors and those are the coil and the control box. A: Metal detectors in general aren’t waterproof as they can’t be fully submerged in water or else they’ll quickly break, this is why getting one which is able to go underwater is vital as they will have a level of waterproofing. If you’re looking for an all-around model in all conditions though, then it’s best to opt for a VLF type of metal detector. Saltwater has minerals in it which can affect how a metal detector functions but specifically this refers to the VLF detectors as they are much more heavily affected by the presence of saltwater and minerals.
High frequency signals have lower penetrability and they can’t be used when searching around mineralized and alkaline soils. Nevertheless, quite often low frequency signals are distorted due to some electromagnetic interference. Furthermore, when the adjustment was done wrongly the searching result will be zero and, on contrast, professionally performed ground balancing allows obtaining the best result. To do this one has to know a lot and be rather experienced treasure hunter.
Depth indicator: The depth indicator is a rare feature on metal detectors. Each type of coil excels at certain things and struggles with others, so be sure to think about what you will be using your detector for before choosing your coil. From our tests, we found that the Garrett – Ace 250 was best at locating gold, while the Bounty Hunter – Tracker IV, Bounty Hunter – Gold Digger and Treasure Cove – TC-3020 all tied for a close second place. It seems that gold prospecting is the most difficult of all types of detecting and experienced detectorists suggest that you master coin shooting before searching for gold. The enthusiasm of the ‘gold rush’ is still alive and well for some people and if this is the case with you, you are going to want a detector that is especially well adept at locating gold.
