The deepest that a Classic metal detector with AR object visualization can detect is approximately 1m or 40 inches. But detection depth depends on various circumstances, for example, the material and size of the target. The great factor in detection depth is soil material and its magnetization.

Gold metal detector that visualizes buried metals on your smartphone.
Metal detectors can be waterproof, this is a very important feature, most of the detectors can be used in wet areas but this doesn't mean they can be used in the water. When we talk about waterproof metal detectors, we refer to the search coil and the rod of the detector. This allows us to place the search coil in the water (rivers, streams, ponds). But this kind of waterproof metal detector can't be used underwater when scuba diving.
