There is plenty of treasure that you will find trapped under the sea, waiting to be found. Generally, though, having to hunt for that treasure has been a lot harder than it is on solid ground as metal detectors were not able to go below the water to search for that precious, lost metal.
Thankfully, though, today, technology has greatly advanced, and now, we are able to reach beneath the waves and with the best waterproof metal detector, we have a much better chance of discovering a lost piece that was once a part of our human history.
Before you are able to do that, though, you would need to buy one and that would involve checking the depth, accuracy, and detection type among many other factors.
When it comes to the detection type, these types of products usually fall into one of two categories and that is either they have a very low frequency (VLF) detection or they have a pulse induction (PI) type and these two have their merits, although, the PI models tend to be more expensive than their rival.
That extra expense is majorly because of the fact that they are not sensitive to minerals that are found in the ground which also makes them better for use in saltwater as well. While this is a boon to this model, they do have their drawback, and that is of struggling to avoid detecting junk.
VLF detectors are better at ignoring anything else and are mostly focused on what you wanted to find which are the precious metals and antiques. If you are in freshwater with low mineral content below, then a VLF would be the best option but for other conditions, then a PI model would be a better option for you.
Well, figuring out what it is you will be doing with your metal detector and where you will be using it will be of great benefit to you as you will be able to make an informed decision on what detector you would need to get.
