Blackdog for a water detector?

If we look at the different stores in the world, we will find that almost all stores do not have dishes other than those that come standard with an underwater detector. Blackdog has created dishes for almost all underwater detectors on the market, and they are specifically made for this use, since they are hardly affected by salinity and can be submerged several meters deep. They are compatible with almost all metal detectors. The Blackdog coils are capable of working in a hybrid way, they can work in normal detectors, both multifrequency, both for impulse detectors.
