Fresh Water and Sea Water Treasure Hunting
Treasure hunters’ objective in every hunt is to detect or grab fortune. This can be achieved easily and conveniently through metal detecting. Metal detecting can be divided in several categories: Gold prospecting, coin and treasure hunting, which can be subdivided to underwater detecting.
Before anything else, treasure hunter enthusiasts should first consider the kind of hunting they will do to fully exercise the power and capabilities of their metal detector. Choosing the right equipment for your treasure hunting need can completely aid you to achieve what you really want-fulfillment in every treasure hunt on land or underwater.
One of the most exciting hunting spree treasure hunters go for is the kind done in underwater. Whether you’re wading in a few feet of water or scuba diving on antique ship-wrecks, you’ll need the waterproof ability of an underwater detector. Underwater detecting can be in freshwater or sea water. Numerous metal detectors can only be good for fresh water, or only for sea water, while some detectors possess the capability to be good in both. But yes, indeed, there are differences between a metal detector for freshwater and for sea water.
Studies say that some detectors work better in fresh water than in salt water, and also the other way around. You see, underwater detectors designed for use in fresh water will have trouble working in salt water because of mineralization. Same way that if you plan to go deep sea diving with your detector, you also need to make sure it isn’t designed just for wading. The metal detector you should use in this will need to be able to withstand the pressure at deeper depths.
Another consideration you should also put in mind when choosing an underwater type detector is its weight. Sure it’s much easier to carry heavy objects around underwater, but unlike Superman, you may still get tired. There are several underwater metal detectors that have more than one arm to operate; some may get used to carrying this, while others might find this inconvenient, especially when going deeper underwater hunting.
Fresh water and sea water metal detectors vary on its type of coil. For fresh water, you will need a specialized coil. Salt water, on the other hand, will use a different one that is compatible with its depth and conductivity.
There are detectors for underwater use that have search coils of different sizes. Usually, the sizes range from 7 to 10 inches in diameter. The downside of using larger search coils is it usually can’t detect small objects or pinpoint targets accurately. On the contrary, larger coils have the advantage of being able to search deeper.
These pieces of information can help you determine what size of coils or specialized coils to use when going fresh or sea under water hunting. But then again, thanks to modernity, there are metal detectors that offer convenient underwater hunting for both sea water and fresh water.
Now, that’s the benefit of being informed! Go and get to know your target underwater detector before you purchase it.
Be back with gold, and not fishes! Have a happy underwater treasure hunting!
