Detectors that can go more than 10 feet deep are intended more for diving, while other detectors are made for detection in rivers and lakes.

Aside from being waterproof, underwater metal detectors work differently to find metal through water, wet sand, and various floors.
There are two types of underwater metal detectors:
Ultra-Low Frequency (VLF) Metal Detectors
Underwater pulse induction metal detectors work by sending electronic pulses that are unaffected by water and minerals. They send fast electronic pulses that are sensitive to precious metals, so they can detect them through the wet ground and are the best choice for use on beaches or deeper treasure hunts.
VLF metal detectors work through water and wet surfaces, but the coils are more affected by mineral ground, but you can adjust the sensitivity settings further. She can pick up coins and small jewels, but she won’t pick up everything.
