How the Underwater Metal Detecting Works

The first thing to consider is the type of technology you are using. There are two choices. You can either use Pulse Induction (PI) or Very Low Frequency (VLF). Both of these have pros and cons. Let’s take a closer look at these technologies and the differences between them.

Let’s start by looking at PI and how it operates. In this case, it operates by sending an electronic pulse into the ground. It then stops and listens for the response. This will give you a good idea of where the targets are. It’s also going to be largely unaffected by things like underground minerals and high salt concentrations. The biggest weakness is its inability to discern between valuable and worthless items. Because of this, you might find yourself having to dig through more trash to get to the target.

On the other hand, the VLF will be better at filtering out junk signals. It does this by sending out a continuous sine pulse. This allows it to detect the changes in the magnetic field produced by these items.  The higher frequency waves are better at locating objects that are close to the surface. The lower frequencies are better at finding those that are at a lower depth. Usually, you’ll be able to adjust these frequencies, so you’ll be able to find what you are looking for.

So, which one should you be using? This will often depend on the conditions that you are diving in. If there are a lot of minerals or salt in the water, it might be best to use a PI. This device will be better at filtering out these signals. On the other hand, the VLF will be better at identifying potentially valuable targets like coins.

Salt Water Mode & Depth

You’ll need to make sure that the detector is prepared for underwater conditions. Because of this, you should check that it will be able to cope with saltwater. If you don’t this can potentially get into the device and cause problems. Most detectors will be equipped with this function, but it’s best to double-check.

When searching for a good underwater metal detector, you’ll need to consider how deep it will be able to operate. This should be included as part of the product specifications. To find this information, look at the depth rating. This is the maximum water depth that the device can be used in.

Price & Accessories

Next, you’ll want to consider the type of accessories that are included with the Underwater Metal Detecting. Though you will be able to purchase these separately, it’s best if they all come with the detector. There is a range of accessories that you should be looking for. First, it can help to get underwater headphones.  This will allow you to hear when you get a hit.

You might also want to use a dive pole. This will make it easier for you to hold onto the detector as you are swimming. You might also want to get a carry bag. This will make carrying and transporting the detector a lot easier. We’ll discuss this in more detail later.

Lastly, it’s important to consider how expensive the metal detector will be. Understandably, you want to avoid spending too much money. But it’s best to pay a little to get something which you know will be able to last for a long time.
