Choosing The Best Underwater Metal Detector At The Best Possible Price

In this article, we aim to help you find the best underwater metal detector for your needs and also look at some of the main strategies that professional treasure hunters and archeologists use in order to increase their chances of finding something of value underwater.

Some of the greatest treasures are underwater. However, finding them is never easy and specialized equipment is required in order to detect jewelry or historical artifacts. When it comes to the preferred tools of modern-day treasure hunters, the most important one is the metal detector. These devices use magnetic fields in order to find objects made from a variety of metals, ranging from copper and nickel to gold and bronze.

This having been said, not all metal detectors are created equal and being able to choose the right one for the job is essential to making your treasure hunts as lucrative as possible. There are several types of devices, in terms of design and each has different advantages and disadvantages.

The technology that powers the metal detectors has been around for several decades and has now reached a point where manufacturers are coming up with devices that can be used at depths of 100 feet or more.

What to look for in a quality underwater detector?

Finding a quality metal detector can be a difficult task by itself, however, finding one that can also work deep underwater may be a lot harder if you do not know exactly what to look for. Models that are manufactured to work underwater follow the same functioning principles of the ones that are used on land, however, there are a few differences that you must keep in mind:

·         What kind of water will you be using it in?

Not all models can handle saltwater. Although they are advertised as being waterproof, salt can easily cause any exposed metallic parts to oxidize and break down, even if you regularly wash the detector after you use it. If you intend to go hunting in saltwater, look for devices that are specifically designed for this kind of environment. They may be slightly more expensive, but they won’t rust after using them a couple of times.

·         What depth do you want to dive to?

There are two main types of underwater detectors: regular, telescopic models and ones made specifically for scuba diving. Both can vary in terms of what depth they will work at, but they have vastly different designs, which can influence the way you use them.

Regular waterproof models are considered to be some of the best underwater metal detectors due to the fact that they have a telescopic stem and a large coil that will easily find smaller items without having to go several times over an area. The main downside with these is that they are heavy and bulky, so you may find it difficult to swim while holding them in your hand.

The alternative is a scuba diving metal detector. These devices work just like the regular ones but are shorter and much lighter. While they are easier to carry, especially while swimming, they have 360-degree coils, and lack a stem. Scuba diving models usually resemble handheld metal detectors that you see at airports but can be taken to depths of over 250 feet.

Which one of these types of models you choose is up to you, however, the standard ones are generally more useful in shallow water while the smaller ones will work better if you dive deeper.

Tips for finding treasure underwater

Even the best waterproof metal detectors can’t really compensate for experience, however, there are a few secrets that professionals use in order to maximize their chances of finding valuable items and historical artifacts:

  • Go hunting AROUND hotspots – Known historical sites and treasure hunting hotspots are usually picked clean due to the fact that most people go directly to where they know others have found valuable items. However, a lot of items can also be found in the surrounding areas. Treasure hunters tend to ignore these places which leaves them full of undiscovered items;
  • Always carry spare batteries – You won’t change the batteries while underwater, but it is useful to have spares on the boat or onshore. While there are underwater metal detectors that can operate for up to 12 hours on a single charge, some models may stop working after a couple of hours. If you’ve got a device that works with rechargeable 9V alkaline batteries that can also be replaced, get a couple of regular ones and use them when necessary. You’ll be able to recharge the other ones when you get home;
  • Use all-metal and discrimination modes alternatively – Professional treasure hunters often alternate between the two modes in order to ensure that they don’t miss anything. Even if you’re looking for gold items, you may find objects that have historical value, regardless of what they are made from;

The Top 5 Best Underwater Metal Detectors
