Thought you could only hunt for treasure on land? Underwater metal detectors make it possible for treasure enthusiasts and veterans to scavenge the open waters without a worry.
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 Detector
There are typically two types of underwater detectors:
1. Pulse Induction Metal Detectors
Sand, wet salt and soil minerals do not affect pulse induction metal detectors. These detectors are sensitive to precious metals and works by transmitting electronic pulses in the ground. Pulse induction metal detectors are best suited for use in saltwater and for diving. However, this metal detector does not have the capability to separate trash from useless objects.
2. Very Low-Frequency 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 Underwater Metal Detectors
Still wondering why you should invest in an underwater metal 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.
Essential Items To Invest in when you own an Underwater Metal 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.
- Carry Bag: A handy carry bag protects your expensive metal detector from sand particles, especially if you are headed to the beach.
- Tracking Device: Ensure you have a tracking device installed in your metal detector. This will make it possible for you to notify other users in case you are in trouble. A tracker makes it possible for you to notify a search team in case you get lost at sea.
- Tank and Snorkel: A snorkel and air tank aids in breathing, allowing you to explore deep waters without losing breath.
Conclusion : buying underwater metal detectors
These are a couple of factors you should keep in mind while investing in a quality underwater metal detector. Ensure you purchase a reputable product that will not end up being a burden for you in the long run. Good luck!
