A variety of underwater metal detectors are available on the market today, offering treasure hunters a good way to search for lost valuables at the water’s edge. What are the main styles of underwater metal detectors being sold today?
In general, three main types of underwater metal detectors are currently sold online and in stores. They include: broad band spectrum (BBS), pulse induction, and very low frequency (VLF) metal detectors.
What Are Broad Band Spectrum (BBS) Metal Detectors?
Broad band spectrum (BBS) metal detectors function using a series of signals, emitted in more than one frequency. Capable of emitting up to 17 different frequencies, broad band spectrum (BBS) metal detectors offer good discriminating capabilities with a good level of accuracy in determining the difference between trash and treasure.
What Are Pulse Induction Metal Detectors?
Pulse induction (PI) metal detectors function by emitting a series of electronic pulses into the ground beneath them. The pulses, which are short and quick, are quite sensitive to precious metals. Unfortunately, this type of detector does not discriminate well between trash and treasure, leading to just as many poor finds as valuable discoveries. The pulse circuit goes deeply into the ground through the water. Pulse induction metal detectors perform well no matter what type of ground condition exists.
What Are Very Low Frequency (VLF) Metal Detectors?
Very low frequency (VLF) metal detectors function using a low frequency range of 3 to 30 kHz. This style of detector has good discriminating capability and can sort out the trash from the treasure. A VLF detector is quite sensitive to certain types of valuable items including jewelry and coins. Unfortunately, this style of equipment can be affected by the minerals contained in the ground. Many of these models offer a sensitivity adjustment as well as a ground-balance adjustment, providing an opportunity to tweak your findings.
Each of the above styles of underwater metal detectors can be used to search for valuable items beneath the water. It is important to be aware of your surroundings when searching for underwater treasures and to wear appropriate footwear and clothing.
