Types Of Metal Detectors Pulse Induction

It can also find other types of metal so don t think that just because many people purchase it for its ability to find gold that this is all.

Types of metal detectors pulse induction. The pulse induction or pi type of metal detector is a more specialized type of unit most commonly used by treasure hunters searching for items deep under the surface. Professionals use this machine to recover wrecks and track underwater cables. See our complete guide on best beach metal detectors. Large versions of pi detectors are also commonly used at security checkpoints to detect weapons.

Pulse induction machines are not designed to discriminate. The main types of metal detectors are beat frequency oscillation very low frequency pulse induction and industrial. Aquascan aquapulse aq1b diver metal detector review. This type of detector technology is different.

Pi detectors can t distinguish between one type of metal or another they are really useful in saltwater hunts. Pulse induction in saltwater. Advantages of a pulse induction detector. That s because vlf detectors perform so poorly in saltwater.

The kind of metal detector we have built is based on pulse induction pi. Instead of using two separate coils a pulse induction metal detector uses one coil that both transmits and receives electrical currents. Another common type are stationary walk through metal detectors used for security screening at access points in prisons courthouses and airports to detect concealed metal weapons on a person s body. Pi machines also tend to be a bit heavier since many are built for diving.

This type of metal detector sends powerful short bursts pulses of current through a coil of wire. The aquapulse is designed for deep diving and can withstand 100 meters of pressure. So if you plan to hunt beaches where there s lots of trash go with a multi frequency. A pulse induction detector can often see smaller pieces of gold than other types of detectors.

Pi systems may use a single coil as both transmitter and receiver or they may have two or even three coils working together. These currents are released in pulses with anywhere between 100 to several hundred pulses in a second. Pi detectors aren t as popular as vlfs but they definitely have a purpose to serve. The aquascan aquapulse is a top notch piece of kit and many consider it the best pulse induction metal detector for divers.
