Different Types Underwater Metal Detectors

Send a series of short electronic pulses into the ground. These electronic currents are insensitive to precious metals but are unaffected by salt sand or ground minerals. The best Pulse detector for diving and saltwater beaches is the X-ray. The Pulse circuit can be used for deep searching and in difficult ground mineral conditions. You will need to dig more trash items if the PI circuit has limited discrimination abilities.

Apart from being waterproof, underwater metal detections are able to detect metal in water, wet sand, and other textured ground. Two types of underwater metal detectors are available: the pulse induction (PI), and the extremely low frequency (VLF), metal detectors. The underwater pulse induction metal detectors transmit electronic pulses that are unaffected by water or wet minerals. They emit rapid electronic pulses sensitive to precious metals and can be detected through mineralized or wet ground. The best option for treasure hunting or beach use is the PI metal detector.

The very-low-frequency metal detectors can work through water and wet surfaces. However, the circuits are more sensitive to mineralized ground. To ensure VLF metal detectors can work on mineralized surfaces, you can adjust the sensitivity settings. They can detect small amounts of smaller metals but are sensitive enough to detect jewelry and coins.

Which type of underwater metal detector is best for you? 

It is important to take the time to choose the right type of underwater metal detector. We now know the location where your unit will be used, so let’s look at some other things you should consider. Are you going to hunt in salt or freshwater? Is this a primary detector? Or will it be used in conjunction with a separate unit to detect metal on the ground? A Pulse Induction is the best choice if you plan to hunt in saltwater. If you do choose to purchase a VLF underwater detector, make sure it has a saltwater model. Consider how deep you’ll be diving if you plan on doing so. To make sure the detector is suitable, check the depth rating. It is not the depth at which it can penetrate the ground, but the depth below the waterline where it can be used. You will need a short diving pole if you plan to do snorkeling or diving. This will make the model more comfortable to use.

What accessories do I need to succeed?

Here are some suggestions for basic equipment that every underwater treasure hunter needs. While you can always buy more items, later on, these are the essentials. Headphones can help you hear the deepest targets and block out external noises. All underwater detectors come with waterproof headphones. The Carry Bag protects your detector well and makes it easy to transport. A trowel is a must-have for beach hunting. A few Metal Detector Sand Scoops are also helpful. Your recovery will be much faster if you have a beach sand scoop.
