no
it cannot detect plastic guns or 3d made guns unless the bullet is in the gun
It is called a "metal " detector

All airport metal detectors are based on pulse induction (PI). Typical PI systems use a coil of wire on one side of the arch as the transmitter and receiver. This technology sends powerful, short bursts (pulses) of current through the coil of wire. Each pulse generates a brief magnetic field. https://detectorly.com/beginners-guide-metal-detecting

almost all modern metal detectors are waterproof, since many people who enjoy this hobby do so on the beach. it depends on the coil inside, some are simply waterproof, and some are completely submersible
