Buying a metal detector may be intimidating as there are various controls and features that you may not be accustomed to. Which type of detector should you get and what features might you need? Before you decide on the detector to purchase you should first think about the type of metal detecting you wish to do. Do you want to search for gold or relics, or perhaps you want a detector to use in the surf or even underwater. You can obtain more about types of metal detecting at How to Choose a Metal Detector. In this article we’ve put together some information on the features of metal detectors and how they work.
Metal Detector Functions
Depth – Detectors are designed to work at diverse depths so find out the specifications of the detector.
Signals – Detectors use a choice of methods to warn the operative when a target has been found. Audio or visual warnings are most common. Cheap detectors will use the same sound for every types of metal while a dearer machine may have different beeps which depend on the metal of the target. The higher-priced detectors frequently have well-defined tones for different types of target, for example one tone for gold, another tone for relics.
Modes of Detection – Controls on a lot of detectors can be used to adjust settings depending on the type of metal you are hunting for. This may be coins, jewels, relics or gold. A few detectors perform in various modes at once whilst others permit you to hunt in each mode separately only. Setting the mode for the type of metal you are hunting for can aid you in eliminating false negatives.
Ground Balance – Exceedingly mineralised earth can get in the way of detection so lots of detectors have settings to allow you to adjust for this. Costlier models can automatically make adjustments for mineral deposits in the soil and do away with false signs.
Sensitivity – Sensitivity can be changed on most detectors so they are less responsive to ground minerals or any other items. This can be of use in eliminating trash but can lead to missing some objects. Beginners should set out by looking at all targets except for areas with elevated levels of scrap until they get a feeling for the machine.
Metal Discrimination – A number of machines can be adjusted to remove signals from iron, others have enhanced sensitivity for gold or silver
Weight – You may be using the metal detector for extensive periods so it is essential to try out the weight and make sure it is easy for you to use. Some can be mounted on a waist box to eradicate arm fatigue.
Batteries – Nearly all detectors operate on AA batteries with operating times that can vary between four hours to more than 25 hours. You could use rechargeable batteries and you should always take some spare batteries with you.
How Much?
Now you have an idea of the functions you need it is time to look at the various models offered and pick out one within your finances. A good used machine will permit you to purchase a detector with added features at a lower price than purchasing new.
