![]() Pushing down too hard on the probe or not keeping it equidistant from the surface can often lead to false alarms. ![]() Some false signals are due to the way you use the pinpointer. How can you prevent false alarms with a pinpointer? These probes tend to give more false positives because of their greater sensitivity. High frequency pinpointers use shorter wavelengths, and so are suitable for smaller objects which are closer to the surface and have lower conductivity like gold and iron. They are also ideal if you're looking for objects of high conductivity such as silver. Low frequency pinpointers use longer wavelengths and are more accurate at greater depths. Your choice will depend on the location you'll be searching, and what you're looking for. The pinpointers on eBay range from 3-100 kHz. What role does the frequency of the pinpointer play? Special features: Some models have auto retune, a LED torch, and/or a second probe cap with digging blade.Modes: Audio and/or vibration mode notify you of a find, or alarm mode (audio and LED light) signals an inactive misplaced device.Colour: Although available in many colours, brightly-coloured pinpointers can be easily found in poor light or dirty water.Power source: Think about the voltage/number of batteries, battery hours, and if they're rechargeable. ![]() Location: For underwater use, check if the pinpointer is waterproof, and to what depth.Dimensions: Consider the size/weight of the device to ensure easy use and portability.Manufacturer: Select among the range of branded and unbranded pinpointers.To make sure you choose the most suitable pinpointer, take the following factors into account: eBay has a wide selection of pinpointers which can be used on any terrain and in all weather conditions. Some compact models can also be used as metal detectors if you have security concerns for a venue or business. Whether you're a professional archaeologist or amateur hobbyist who enjoys the excitement of looking for buried treasure, a pinpointer is an essential piece of equipment. It can also prevent possible damage to the object as you'll know exactly where to dig. ![]() This means that you can save valuable time and effort digging around the approximate location of a find. Dr.Make Your Treasure Hunting Easier with a PinpointerĪ handheld pinpointer enables you to home in on a signal with greater accuracy.Garrett Pro Pointer II Metal Detector 1166050.Minelab Equinox 800 Metal Detector Multi IQ Waterproof.Garrett EuroAce Metal Detector Made in USA Part 1140360.Outsunny Metal Detector Underground Gold Coin Digger Searcher Treasure Jewelry H.Used by professionals and DIY enthusiasts alike, multi sensor detectors are handheld and designed to identify iron, copper and aluminium pipes, metal and wood studs and live AC wires that are concealed within walls. Once the main metal detector has identified a target, a Pinpointer detector can home in on it, drastically reducing the time taken to get finds out of the ground. Usually the size of a mobile phone, they are cylindrical and have 360 degree side detection as well as tip detection. Pinpointer metal detectors are an essential ancillary item for many detectorists. Considered to be superior by many users, these models are ideal for serious enthusiasts and professionals alike. ![]() PI (Pulse Induction) uses a single coil and is able to pick up metals far deeper than VLF and BFO models. VLF (Very Low Frequency) is the most popular technology used in a detector and uses a receiver and a transmitter coil with phase shifting, great for serious hobbyists. Types of Metal Detector TechnologiesīFO (Beat Frequency Oscillator) is the most affordable type of metal detector to purchase but they lead to less accuracy and have less control than other types. As a rule of thumb, the more advanced the metal detector is the more information that will be provided about the type of find and depth. In its most basic form, metal detectors consist of a search coil (of which there are five kinds), a shaft, a control box and a stabiliser for the hand or the arm. In fact, with hoards being found with values into their millions, the sport of metal detecting is booming. There are metal detectors for industrial and security alongside those used for recreation and archaeology. ![]()
