Pinpointer: what it is, features, how to choose

Pinpointer is a special kind of metal detector, a very compact device that easily fits in a pocket. How does it differ from the classic metal detector? Let's consider the features of pinpointers, application and a few tips on the choice.

Features of pinpointers

An ordinary metal detector of a large size with high power fixes that at a certain depth there is a detail of metal. To find it, it is often necessary to dig approximately one cube of soil. The reference point is not specific enough. Pinpointer much more accurately indicates the location of the metal object in the soil. This saves time and effort when searching. Pinpointers do not only scan the ground. They survey the bottom of water bodies of great depth, even the seabed.

Pinpointer is often used in conjunction with a classic metal detector. The large device determines the area where the metal object is located. After that, a hole is dug. Then turn on the Pinpointer and look for a more precise location of the metal object.

The peculiarity of these devices is that they have a low depth of detection. Because of this, the pinpointer does not trigger on objects that lie deeper. This allows you to search more purposefully. Also, the shallow depth of search helps the device to capture small objects. Larger objects located in depth do not interrupt the signal.

How to choose a pinpointer

Pay attention to such characteristics of the device:

• Resistance to water at least IP66 and protection against shocks. When searching for metals in the soil or in water, such insulation is necessary.
• Increased autonomy. It is important that the battery capacity is sufficient for operation. The average autonomy of pinpointers from 12 to 70 hours. This depends on the specific model, the capacity of its battery. Battery-powered devices are often less energy-consuming.
• The backlight option comes in handy to look for metal objects in the pit.
• You need precise sensitivity settings and different trigger levels.
• The device should turn on and off instantly.
• Vibration is a useful indicator. It helps to instantly feel that the device has triggered and locate the metal more accurately. Also this option helps if you need to work quietly without attracting attention. You can turn off the sound signals and focus only on the vibration.
• The ergonomic shape of the pinpointer is important for the convenience of working with the device.
• A highly sensitive antenna will more accurately detect even very small metal objects in the soil.

A quality pinpointer has an instantaneous and stable beeping sound. It has no false signals and does not react to the frequency of a classic metal detector that is nearby. The tip has a scanning range of 360°.

Pinpointers are not only needed to look for coins or other metal objects in the ground. They are used in repair and construction. Pinpointer detects electrical wiring in walls or the location of drywall profiles.
