How to Select Waterproof Metal Detectors: The Comprehensive Guide
Price
First of all price is the basic element for selecting the right type of model. You want the investment in detector be worthwhile. It can cover your unique requirements with an effective price. The entry level metal detectors are able to give you fun and enjoyable experience. That can be advisable for beginners who do not have enough experience.
Waterproof
Pay attention to the waterproof level if you care about this parameter. Most machines have such features. But some could not ensure the coil and control box can be protected from water. And check if other accessory parts have an acceptable waterproof level if you need.
Pulse induction
There are some technologies you should consider about before buying. Pulse induction (PI) is a technology not designed for discriminate. It could be good choice if you are hunting in some place with trashes. A lot of specialty machines use it in high mineralization areas. The benefit is it goes deep in mineralized areas such as saltwater beaches. Metal detectors with PI levels can dig through salt and iron. It reports on all metal materials without any discrimination.
Frequency
Most detectors apply very low frequency (VLF). You can use these machines to hunt for coins, jewelry and so on. It can be considerable if you are beginners. The other type is multi-frequency (MF) detectors. You can use it for saltwater and other detecting. That can be a good choice if your budget allows.
Coils
Another thing to consider is the coil. You need to think about the coil size and type before choosing. In general cases a larger coil enables greater depth. But the ground conditions and mineralization also play a role. As large coils make a better depth, it detects more of the ground and deal with more signals. Such processing in mineralized soil may lead to false detecting and missing targets. In this way you have to reduce the sensitivity and depth. On the other hand a smaller coil catches less ground and you can promote the sensitivity.
Weight
The metal detectors can vary widely in feature of weight. Some models are light in weight while others can be quite heavy. Pay attention to how much it weighs if this is the first device you are looking for. It will be better experience if you take the lightweight device to hunt for several hours. And if you have problems with the arm or shoulder, consider the light ones. Some models can be heavier but not a monster. You can choose it if you have experience to handle it for hunting tasks.
