Phase Induction: Most sensitive of all, a phase induction design uses only one coil.Very Low Frequency: With two coils in the search head, these detectors are more powerful and expensive than BFO models.These are the simplest and least expensive detectors. When the search coil encounters metal its field changes and the other one doesn't. Beat Frequency Oscillation: These detectors have two coils, one in the head and one in the handle, with an oscillator connected to both.There are three main kinds of metal detector, each of which works in a slightly different fashion: Because metal is conductive it responds to electromagnetic fields, and that causes a corresponding change in the field. How Do Metal Detectors Work?Īll metal detectors work on the same basic principle. Give it a try it can be both fascinating and rewarding. Not only does it get you outside, but it also gets you moving around so you can actually get some exercise when following the hobby. Many people use metal detectors for fossicking and prospecting throughout Australia, both above and below the water. Typically, the best stuff worth having will cost a pretty penny, but even so, as a must-have accessory for a diver, it’s invaluable.While most people think of industrial metal detectors as those used in the food and garment industries to detect potential contamination, metal finders have a lot more uses than just that. Of course, this type of quality and tech will tip the budget towards the high end. With pulse induction as the technology that drives it, it can be used anywhere. It’s tool-less and the battery compartment is accessible by removing the rear handle knob.
The closer it is to the target, the faster and brighter its signals get. Since it’s made for diving, it alerts the user via light and vibration. Diving anyone? It actually covers some good ground, and its effective depth detection is between 4-6”.
The entire 17” unit is submersible to 100 feet. Sure, you’ll be on your knees, but where it really shines is with the fishes. While pinpointers are designed to be additional tools to aid a full-size metal detector, there really isn’t anything stopping you from using it as a substitute metal detector when you’re in a bind. To have PI tech in your hand at this price, the F-Pulse lives up to expectations. Of course, you have both audio and vibrate indicators, lost mode alarm after five minutes, and 2x AA battery operation (not included). The LED light is adjustable, so you can adjust its intensity for the setting you prefer. It’s warrantied for 24 months from the date of purchase, so be sure to contact them if you have any issues. This is a defect and Fisher Labs will address this issue. However, with its adjustable sensitivity, you may find that the highest setting may cause constant falsing. The F-Pulse is extremely sensitive, and in most cases, this is a good thing. This also means that saltwater hunting is within your grasp, especially as it’s waterproof up to 6 feet. Just press the tip into the ground and retune for ground phase match. It has great detection depth with pennies often found at 3.5”, and as a pulse induction pinpointer, its ability to eliminate signals from ground minerals is a great asset. The F-Pulse is an excellent, high-performing pinpointer.

The AT Pro Pointer has many fans and you may quickly be counted as one too. It also features a scraping blade and LED light for faster, visual digging. It has a great design with a ruler measurement in both inches and centimeters to judge the depth of a buried object. It has three adjustable sensitivity levels, a Stealth mode which is a vibration-only feature, and proportional audio for target detection. The neat thing about its lost alarm is the fact that it will chirp loudly for a long 60 minutes at which point it will automatically turn off to conserve battery life. The retune button may come in handy as it shrinks the detection field to recover objects faster in mineralized ground. However, saltwater seems to be a challenge. The AT stands for All Terrain, and as such, it’s great for pinpointing in many types of ground.

But, if you can learn how to use it correctly, you’ll get the hang of it. The carrot pinpointer has decent features to offer but its one-button operation makes things more difficult than they need to be.
