Best underwater metal detector

Metal detectors are used to find metal fragments that are hidden within objects or others buried underground. We have seen metal detectors used in entry points like the airports, prisons and courthouses to detect metal weapons a person might be carrying. Metal detectors are popular because they do not raise the issue of radiation exposure, ease of use and are generally cheap. For the treasure hunters, they might need underwater metal detectors to help them collect treasures in water. For the best results, they need to have the best underwater metal detector.

For the purpose of this review, we tried and tested several underwater metal detectors. The Garrett 1140900 Pro-Pointer AT Waterproof Pinpointing Metal Detector, Orange stood out as the best underwater metal detector anyone could buy.

Best underwater metal detector

Garrett 1140900 Pro-Pointer AT Waterproof Pinpointing Metal Detector, Orange

Reasons for choosing the Garrett metal detector as the best underwater metal detector: 

The orange color makes the device visible while immersed in water. The problem with some underwater metal detectors is that they are no longer visible when immersed in water.

The detector is waterproof up to 10 feet. With a depth of ten feet, the user will be able to collect any treasures around the water with the detector working perfectly well.

Designed with maximum sensitivity that helps detect the smallest of targets and nuggets. This will maximize collection of targets by the user.

Quick retuning for either narrow field detection or a large target. If you want to perform a narrow field detection, the underwater detector can easily be tuned for that specific purpose. In addition, should you wish to do a large target operation, tune the metal detector for that.

Easy to use and can be used by beginners altogether. The good thing about this underwater detector is that it can be used by both experienced and the beginners as well.

Measures 2 inch in diameter and 9 inch in height Has a 360 degree scan, scraping blade meaning that the device cannot miss on any target.

Has LED flashlight for the low light uses

Comes with 9 volt battery and a belt holster.

The high the target selection is, the lower the rate of false alarm. The walk through metal detectors are most common, they offer effective and quick detection. At times, you might need to check for metal presence in the water. Some metal detector are not designed to perform here, so you will need an underwater metal detector. They can be used by the construction companies who want to detect for locating cable and pipeline.

For the adventure lovers living near a beach, you might be astonished by the amazing things that you might find beneath the surface. However, you will need a quality underwater metal detector. That’s why you need the best waterproof metal detector either you are a professional gold prospector, in countermine operations or a serious treasure hunter.

Underwater you might find treasures from plane crashes and shipwrecks. Some claim that there are more treasures- coins and jewels down on the sea floor as compared to those you can find on land.

 

The underwater metal detectors work by the help of two technologies:

The two technologies are:

Pulse Induction– the detectors transmit pulse signals very fast allowing the device to ignore a ground with too many minerals present. Most common for deep diving.

Very low Frequency (VLF) – the detectors operate in a frequency range of 3 – 30 kHz and are more sensitive to relics, jewelry and coins. The sensitivity can be adjusted since the low frequency metal detectors can be distracted by the presence of other minerals in the soil. The VLF are mostly used in wet soil, water lines and shallow waters.

 

Underwater metal detectors can be used for the following activities:

Scuba detecting– usually to be used for less than 20 feet deep using a scuba gear.

Snorkeling with a metal detector in both fresh and salty water but has to be less than 6 feet deep.

Shipwreck diving– common when searching for valuable treasures around a shipwreck. This type of metal detecting is more expensive, most riskier and will require expensive equipment as well.

 

Where to use the metal detectors:

Apart from using the metal detectors in the building entrances, there are other areas where a metal detector can be used:

Detecting antiquities

Geological detection. This is common with geologists who want to identify the presence of metal in the soil and rocks that they are studying. Also used to find the location of mines for  specific metal.

Searching for a lost jewelry.

In food processing process. The companies would not want to have some metal in their packaged foods. Therefore, the metal detectors can be put in place to detect the presence of any. The affected package is therefore removed from the line of processing.

The best underwater metal detector should be a necessity to treasure hunters. Let us know what you think about this underwater metal detector in the comments section below.
