![]() Keep electronic products or metal products away from the searching coil. Chemicals may escape from the battery and destroy electronic parts. If you are not going to use the search coil for a week or more, remove the battery. Oxidized metals can cause the target to shift. Need to distance between the search coil and target. To detect deeply buried targets, the sensitivity of the product needs to be increased. Three audio tones with high accuracy If the detector is set to the ALL METAL target mode, it sounds a single tone when it detects any type of metal. Detection depth up to 8.7 inches, leading most products on the market. OT-MD02 has a GAD BAL knob that can eliminate the interference of microelements. The metal detector is extremely perfect for metal detecting activities in the garden, local park, on the beach, and all healthy outdoor locations. ![]() It can detect all kinds of metals such as silver, gold, keys, coins, and jewelry. Comes with a characteristic adjustable ground balance, so that reduces the cause of impurities to find exactly what you need. Buying a pinpointer with ferrous tone ID and/or with varying levels of sensitivity (controlled by microprocessor circuitry) can also prevent you from receiving a false reading from ground mineralisation.SUNPOW Professional Metal Detector for Adults uses an upgraded DSP chip, 10Inch IP68 waterproof coil, a new type of handle. 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.
