Your Guide To Purchasing The Best Underwater Detector

2018 Expert Guide To Purchasing The Best Underwater Metal Detector

Under the deep blue waters, or the murky waters or even the dam water lays a pot of gold for metal hunters. Most of which do not know, but given the right equipment, this should be a walk in the park, or rather let’s say a dive in the water. Many might wonder what kind of metal or treasure might be found underwater? Well, there are many minerals that lay on the bed of many water pools, rivers, oceans or lakes. Most ancient civilizations used water as a means of transport and had some bad luck crossing the waters and lost a lot of their precious stones and metals in there. If you might consider it robbing the older or ancient civilization or not, however you put it, there is definitely some metal, relic or a pot of gold underwater.

So, how do you end up harvesting the stuff (metal/relics) underwater? Having a metal detector that is customized for underwater harvesting is a great way to ensure that you never miss a thing. Well, also depending on your level of experience in metal detecting, you need to look for a device that is custom made to suit your specific level. Some underground metal detectors are custom made for the open sea. These metal detectors are specially designed to detect metallic substance at close range under the sea. When choosing a location, it is important you select the most visited location to increase the odds of finding valuable objects and treasures.

Types of Underwater Metal Detectors

There are typically two types of underwater detectors for both beginners and experienced metal and treasure hunters:

1. Pulse Induction Underwater Metal Detectors

Sand, wet salt and soil minerals do not affect pulse induction metal detectors. These detectors are sensitive to precious metals and work by transmitting electronic pulses in the ground. Pulse induction metal detectors are best suited for use in saltwater and for diving. They are very effective when it comes to deep waters. However, this metal detector does not have the capability to separate trash from useless objects and might be sometimes misleading.

2. Very Low-Frequency Underwater Metal Detectors

These underwater metal detectors operate in the 3-30 kHz frequency and are highly sensitive to metallic objects, such as jewelry and valuable coins. These detectors are proficient in separating junk metals from other relevant metals. However, the metal detector is often affected by minerals found in the field because of its high level of sensitivity. Users are advised to adjust the ground balance control to improve performance.

Difference Between Regular Metal Detectors And An Underwater Metal Detector

Is the underwater detector your typical metal detector? Well, in some aspect they are pretty much the same since they actually deliver the same task, get you the metal you want, but still not the same. They have some various differences in their structure, and the fact that they are used underwater draws the line.

Still wondering why you should invest in an underwater detector? Here are a few differences that separate the two:

 

  • Waterproof: Regular metal detectors are not waterproof and can suffer from extensive water damage that can void your warranty. Always ensure your metal detector is waterproof before testing it out in the sea or beaches. Underwater metal detectors are constructed from waterproof materials to prevent rust. These metal detectors can conveniently be used in large salty water bodies.
  • Pitch: Regular metal detectors use a high pitch sound to denote the presence of metal nearby. Underwater metal detectors do not have this characteristic because sound travels differently in water. Instead, these detectors feature a meter that detects the level of metallic content. Some advanced underwater detectors now include waterproof headphones that eliminate unnecessary noise from the environment. This makes it easier for individuals to hear the high pitch noise produced by the machine in the presence of a metallic object.
  • Weight: Underwater metal detectors are typically lighter as compared to regular detectors. This makes it easy for divers to maneuver the device when they are looking for precious metals under the sea. Invest in a detector that is not too heavy or else it may cause you to sink underwater. Consequently, the detector also shouldn’t be too light or else it will float away.
  • Quality: Underwater metal detectors are manufactured while maintaining high quality standards. This is because these detectors are more complex to design in order to sustain underwater. The materials used to manufacture underwater metal detectors should be waterproof and durable. While this may also be the case for standard metal detectors, individuals can opt for an inexpensive option.
  • Ease of Use: Beginners may not experience much trouble in operating a standard metal detector. However, the use of underwater detectors requires special training and attention. These devices are much difficult or complex to use and are only recommended for deep sea divers who are well trained. Thankfully, most detectors come with a handy guide that makes the device much simpler to use.
  • Cost: Due to its advanced specs and high quality materials, underwater metal detectors are more expensive as compared to standard devices. Standard metal detectors are more affordable and are available in a variety or price range. Users can invest in a metal detector depending on their level of expertise whereas underwater metal detectors are best suited for folks who passionate about scuba detecting or snorkeling with a metal detector.
  • Power Source: The power source found in a standard metal detector differs from that of an underwater detector in several ways. First off, standard metal detectors typically incorporate a normal battery that needs to be charged on a regular basis for usage. On the other hand, an underwater metal detector features a special type of power source that is specifically designed for use in water. Regular batteries are not designed for use in salty water bodies or deep sea. A standard battery is likely to stop working under water that will render the device useless.

Where to hunt for metal with your underwater metal detector ?

When it comes to hunting for metals or rather precious metals, you need to identify the best spots that you could have higher chances of having your harvest. Areas that have a lot of activities are a great target and are highly recommended.

These areas would include surfing areas, docks, beach areas, diving holes or piers. Places where there is a diving board also makes it very ideal for metal detection since many pieces are generally lost in saturated areas where there are a lot of activities. Areas that have fewer people should be given less priority on the other hand.

What Brand of underwater metal dectectors works for you ?

Most brands available in the market that produces metal detecting devices have the underwater metal detector to their name. They vary in the strengths and extent of use when compared to one another and they might have almost the same features when it comes to actual performance.

So then, how will you arrive at your ideal brand if they function pretty much the same? Well, presentation is very ideal. By the first impression, how do you like a product?  Is it appealing for you to even what to go with it under the water?

Another factor to consider what brand to go for is their warranty offers. Warranties less than two years might not be a great option. It would be advisable to go for a product that has two years and above of warranty coverage.

Finally, have you used the product before, or the same line of product before and what was the experience? If you have a specific metal detector brand in mind, then, go for it. Though if you are still torn, you could try to assess the metal detectors you have used before and assess the quality they offered. If they were great, it would be a great recommendation to go for the same brand.

What is the best type of underwater metal detector ?

While buying your metal detector, it is very important to know if the machine will work for you. What conditions are you subjecting it to? You need to know whether you will be hunting in salt waters or will you be going in fresh waters. This comes in handy when also separating the detectors that work on land too.

If you are hunting in salt waters, you then need to go for the pulse induction metal detector. You could still use a Very Low-Frequency Metal Detector but ensure that you lock it at the salt water mode.

The depth also is a great consideration. This affects the function of the underwater detector in that you should ensure that the detector bought can withstand the depths of the water you intend to dive into. Appropriate gear also is highly recommended so as to have the best scuba detecting experience.

Essential Items To Invest in when you own an  Underwater Detector

Scuba detecting can be a challenging yet thrilling experience. Here are a few devices that will make underwater detecting a more enjoyable experience:

  • Waterproof Watch: Time flies when you’re having fun, doesn’t it? A waterproof watch makes it easier for divers to keep track of the amount of time they have spent inside the water with an air tank. This way, they can conveniently time themselves and come up to the surface to replace their air tank.
