Is it really waterproof?

The search coil is sealed and works in streams, surf and shallow lakes. The control housing and display are not described as waterproof, so keep them out of the water.

How deep can it detect?

The 7.5 kHz signal reaches items up to about 6.3 inches underground. Small coins will read shallower than large relics.

Yes. The aluminum stem adjusts from 3.3 to 4.2 feet, which covers most kids and adults.

What do the two modes do?

All-metal mode responds to every target. Discrimination mode filters out iron junk such as nails and bottle caps so you dig fewer worthless items.

What comes in the box?

The detector, a digging shovel, and a headphone connection. Headphones are not included.

Does it work on wet sand?

The coil handles wet sand and shallow surf. Salt water and highly mineralized ground can cause false signals on a single-frequency detector like this.

Our take on the Hongge Waterproof Metal Detector for Adults and Kids

The Hongge is a stick-style starter metal detector with a sealed search coil that works in shallow water, so it suits beaches, streams and parks. It runs two modes: all-metal and discrimination, which filters out nails and bottle caps, and the LCD shows target type and signal strength. The aluminum stem adjusts from 3.3 to 4.2 feet, so adults and kids can share it. It is a basic entry unit: a 7.5 kHz signal reaching about 6.3 inches is shallow next to pricier detectors that hit deeper targets and identify them more precisely.
