Should You Buy Pulse Induction or VLF?

The answer to this question is not so simple but there are some complex calculations. Because you need to know exactly how much mineralization there is in the water you are going to take the metal hunter in. Much also depends on the condition of the hunting ground you are setting.

There are two broad categories of metal detectors: Very Low Frequency (VLF) and Pulse Induction (PI).

Machines using the pulse induction method, usually as a rule of thumb, are better for saltwater or scuba diving. This is because sand has a lot of mineralization, and the effect of mineralization on the machines using the pulse induction method is negligible.

These machines are also capable of detecting metal deep into the ground. However, there is a downside to this machine, and that is that this type of machine does not have a lot of discrimination, and so a lot of unnecessary metal will be detected in this machine.

On the other hand, if you do not have much budget in hand, then the machines using VLF method can be a good alternative. However, with this type of machine you will not get a good advantage in the ground where there is a lot of mineralization.

And so these machines do not become very convenient for saltwater hunting. On the other hand, there is another issue for which many people prefer VLF method machines, and that is that good discrimination can be done with these machines.

And so many types of unnecessary metal can survive your detection during hunting. And so using this machine will save you a lot of time digging out unnecessary things.

Apart from the category of the detector and its water-resistant competencies, there are other issues to ponder. These comprise your financial plan, knowledge level, and which equipment you want. Ensure that your financial plan for additional digging gears and scoops, as these can increase the entire budget.
