Many beach and shallow water hunters ask me whether it is best to invest in a pulse induction metal detector or buy a larger search coil for a VLF metal detector.
In my opinion, you are always better off basing that decision on the beaches you metal detect on.
If you search wide open beaches or stretches of water with a low amount of trash or ferrous targets, a pulse induction metal detector should be the best choice.
People who search on trashy beaches with moderate to high amounts of ferrous targets, may find an extra large search coil on a VLF metal detector a better choice.
When it comes to metal detectors and search coils, everything is about the beaches that you search on.
Using the wrong metal detector or search coil on the beach is the main reason why many beach and shallow water hunters go home empty handed.
Metal detecting with a pulse on a trashy site and digging all targets can be just as frustrating as using a VLf metal detector on a wide open beach with a small search coil.
You must also take into account the types of objects you are searching for, when deciding which set up is a better choice.
If you predominantly search for old shipwreck artifacts, digging all targets using a pulse induction metal detector or an all metal mode is the best plan of action.
Modern finds, such as gold and silver jewelry are more likely to be found in trashy areas.
A large search coil on a discriminating VLF metal detector is a better choice of treasure hunting equipment when trying recover deep jewelry on busy beach sites.
For many beach and shallow water hunters, a pulse induction metal detector or an extra large search coil on a VLF metal detector are very effective game changers in the right circumstances.
It just depends what your local beaches allow you to use.
